Virtual hard disks ( VHDs ) on Windows 7

Posted on September 3rd, 2010 in battery review, battery specs, digital camera battery, knowledge, laptop battery | No Comments »

Virtual disks in the VHD format played so far only for Microsoft ’s virtualization software a role. For Windows 7, virtual hard disks to an important component for backups , XP -Mode , boot manager and disk management. The Home versions of Windows 7 after all a subset of control in dealing with VHD images.

934

The VHD format (Virtual Hard Disks Virtual Disks = ) is used for a long time as an image format for Microsoft ’s virtualization software, Virtual PC. This task will continue to meet under Windows 7 Thus uses some of the XP -Mode a 3 GB VHD with a Windows XP SP3. The rechargeable in Windows 7 Professional , Enterprise and Ultimate is a full virtualization , integrated virtualization software that can , other than the default VHD to create and use with XP.

For Windows 7, the VHD format is supported but by far the virtualization system .

VHD for system image:

Virtual disks in the VHD format created Creating Windows 7 also in the full backup of the system ( ‘ system image ‘). That was already running Windows Vista with ‘Complete PC Backup ‘of the case, but it was with Windows on board means possible , to commit these fuse completely. A shop (Mount ) of the VHD, as to extract some specific data, there is not possible. This requires the installation of the software Virtual PC and Dell latitude d820 battery . For Windows 7, the VHD support is built into the system.

Create virtual hard drives and load:

Disk Management in Windows 7 features in the menu ‘ Action ‘ , the new points’ virtual disk ‘Create and append ‘ virtual disk ‘. Attaching means downloading an existing VHD and selecting the virtual hard disk is done in seconds: The content of the VHD is loaded as a new drive appears in Explorer. Creating a new VHD Disk Management is only useful for pure data containers – a bootable or usable VHD as a virtual system is created only through the virtualization software and Dell gd761.

The loading and unloading of virtual disks in the VHD format can also provide an alternative fully informed of the Kommanozeilen Diskpart.exe tool . The program was expanded accordingly. For example, the command

select vdisk file = ‘\ \ server \ share \ backup.vhd ‘

attach vdisk

binds to a VHD on a network server in the system. An appropriate select / command followed by ‘ Detach ‘ is the virtual hard disk again. Using Diskpart to deal with VHD images is completely scriptbar .

Virtual boot disk:

VHD images, which were of virtualization in Windows 7 integrable and contain a complete operating system , are also bootable under Windows 7 (which is an important caveat : Do not be created with Virtual PC 2007 VHDs bootable !) .

It then suffices to register the corresponding VHD file to the boot manager. The deterrent , but here indispensable BCD Editor Bcdedit.exe the user makes this simple task in itself as difficult as possible :

bcdedit / copy {current } / d ‘Boot VHD ‘

bcdedit / set { … } osdevice vhd = [ C:] \ path \ Datei.vhd

bcdedit / set { … } device vhd = [ C:] \ path \ Datei.vhd

bcdedit / set { … } on detecthal

In the curly brackets { … } is exactly three times that 36- digit identifier ID register that returns the Copy command from the first command.

The example shows how the VHD virtual hard drive is integrated into the boot manager. If the VHD then loaded at startup in the middle should break off , the computer must also be prepared by the Sysprep.exe to hardware independence. Sysprep Windows 7 is included by default at% windir % \ System32 \ Sysprep – simply Sysprep.exe , ‘ select out- of- Box Experience ‘and also activate the option ‘ generalizing ‘.

VHD support in Windows versions:

The Home versions of Windows 7 virtual hard drives support only in part. The boats will VHDs Professional, Enterprise and Ultimate reserved . The same applies for the integrated virtualization (XP mode). The loading and unloading of VHD images using Disk Manager and Diskpart works! but also in the home versions.

5th System Info: An information tool for all

http_imgloadCA1VWC59

Information about your hardware, the Windows settings, installed service packs and hotfixes, network settings, the duration of the system and the saving power from Fujitsu lifebook t4210 battery so on – all that you can bring about various tools in experience. We recommend a tool which, while spartan, because you operate at the command line, but also provides unsurpassed amount of information. His name: System Info. If you call it within a command prompt, you not only get the information you need to gather up otherwise tedious. In addition, you get to information that otherwise remain inaccessible, as the original installation date, and the internal system name for the installation drive.

Tip: With

System info | more

Show the output screen at a time and may continue using space bar. By

system info / for csv – Systeminfo.csv

Leave the result in a CSV file, which you can then open them in your spreadsheet.

6th Fc: compare files quickly

To compare two files, use within a command prompt, type Fc, followed by the file name. For text files, list the issue on any differences line by line. If the two files differ only by a few additional lines inserted, Fc recognizes the similarities: It shows the extra lines, but not all of the following evaluates as different. Instead, it noted a re-match and from then compares the files again with each other. If you do not text, but have to do with binary files, use the / b. This will give you the output in hexadecimal form.

Ip: for the contents of two folders that contain files with identical names, too, is suitable Fc.

k-dir1 \ *-dir2-\ *

Automatically compares two couples with the same file name in folder 1 – folder and 2 -. Do you want to restrict the comparison, instead of giving the asterisk, which records all files to a restrictive pattern, for example, *. txt or *. ini.

7th Robocopy: The synchronization tool

With a robot tool has nothing to do. The name Robocopy will only show that it is a robust tool is to copy. Since it is part of Windows Vista. XP users, it will also free by the Windows 2003 Resource Kit download and install.it also can save power of lifebook t4215 battery. Robocopy, you can not just as a leader, but also as a replication tool used copy. The difference is crucial: Pure cloning tools to delete the destination directory never anything. A replicator, however, has the task to keep directories in sync, this may well include files to remove the target directory that does not exist in the source directory. The / e alone about Robocopy copies the contents of directory including all subdirectories, source-to-finish:

Who needs the new – generation netbook ?

Posted on July 27th, 2010 in battery maintain, battery review, laptop battery | Comments Off

The Eee PC has brought the ball rolling , now comes the second generation of Netbook . The lot is better , but some things are even worse.

270

Who wants to go on the way to the Internet, write articles or view photos and movies , has a problem: cell phones and smartphones are handy , but have a small display and a mini – keyboard. Laptops are relatively large and heavy,and the it is important to save power of xps m1330 battery , In the niche between cell phone and laptop have the Netbooks made wide ( in this very niche , but Apple will now place the new iPad ).

These mini computers are not much bigger than a paperback book , only weigh about a kilogram and have a long Dell xps m1730 batterylife. The most fuel-efficient models run for ten hours before they need the outlet. Even the low price makes them attractive : most netbooks costs 250-400 € .

If you want to do simple computer work on the road , a netbook is ideal. A laptop can not replace the mini – computer , however. First, they are clearly not as well equipped : they lack such as a DVD drive. The netbook also offer less space on the hard disk – usually only 160 or 250 GB. Current notebooks have at least a 320 or 500 GB hard drive.

Another drawback : most netbooks have a small monitor with low resolution. Then less image content can be seen as on a notebook , especially in height. This forces the user, for example, when surfing the Internet to frequent scrolling. Even when computing speed netbooks are significantly behind notebooks: Netbooks are about as powerful as five years old notebooks. In everyday life, you realize , for example, the fact that programs run more slowly or working with multiple programs need more time. For computationally intensive applications such as sophisticated photo editing, video editing or 3D games are too slow netbooks .

The second – generation netbook – this is new

271

But Netbooks work very sparingly. The new generation is to make even better. For them with the Atom N450 processor and chipset NM10 , both developed by Intel under the name “Pine Trail . Older Netbooks work with Intel processor and chipset. However, there are graphics and memory controller unit or integrated in the chipset and not, as in Pine Trail in the processor. To make the new netbooks more economical , smaller and cheaper and less power from inspiron 1501 battery .

The second innovation is Windows 7 : most manufacturers have skipped the resource hog Windows Vista and now provide their netbooks with the stripped-down “starter ” version of the new operating system from Microsoft, which itself is working fine on the mathematically impaired mini – computers. The PC World has brought the first Pine Trail netbooks to the test : the Asus Eee PC 1005PE , the HP Mini -Note 210, the MSI Wind U135 and the Samsung N220 .

Connections : This is important for WLAN and UMTS

Posted on July 19th, 2010 in battery review, battery specs, laptop battery, notebook review | Comments Off

Advantages: Who SSD automatically equate with performance , can adopt this idea – at least for the low-cost Flash solutions, as used in netbooks used. In terms of performance they put on traditional hard drives by little . The advantages lie elsewhere: They are lighter , more robust , make less noise and less heat develop .

The memory in such Netbooks example, can then be sent by SD -Card. Some manufacturers also an online store is part of the offer, where you can outsource its data. Sizes 20 to 30 GB is quite common here .

Connections: Make sure to have as many USB ports netbooks in general, less interfaces than conventional notebooks and presario r3000 battery . Almost all netbooks bring a VGA port for driving an external display and an Ethernet port.

7911

Back to the basic structure usually includes audio connectors (In / Out ) and a card reader. The crucial link with the outside world manufacture the USB ports : most netbooks have three, some models have to make do with two – this principle applies : the more the better. Far less an Express Card slot is found , but which would be helpful for some extensions.

Facilities: Try before you buy absolutely the touchpad , we recommend trying the keyboard and touchpad, because the differences are quite noticeable. The 10 -inch devices come with a key pitch of 17.5 mm – for standard keyboards is 19 millimeters – usually a much better feeling than to write the keyboards of the 8.9- inch models . The touchpad is just for the scrolling of paramount importance if no mouse is available. Here is to try it .

Connections : This is important for WLAN and UMTS

Most Netbooks spark even in the WLAN according to the standard 802.11g. Some aspire 1690 battery manufacturers now incorporate the powerful 802.11n.

With a netbook would one actually go online to always – a UMTS solution suggests itself as a natural. Many netbook manufacturers offer models that already have an integrated UMTS modem. With regard to the handling , it is certainly the easiest solution if the SIM card in the device itself disappears.

Phone as a modem: Who calls a Bluetooth UMTS Smartphone his own , should look for when Netbook on appropriate Bluetooth support. The right service plan can be provided , then may use the phone as a modem sense . The usual for Smartphone contracts amounts of data with the Acer aspire 3000 battery but quickly exceeded.

Rates: Some mobile operators offer sponsored Netbooks in connection with a UMTS contract. Whether that counts for you, depending on your usage . For one or the other suffice as a safe UMTS Stick with a daily flat rate.

The cheap laptops

Posted on July 2nd, 2010 in battery maintain, battery specs, battery tip, digital camera battery, laptop battery | Comments Off

3D performance costs more

The cheapest notebooks have one thing in common: they are not or only very limited suitable for 3D games. This is due to the mathematically graphic logic that is integrated in the chipset . If you use the notebook PC and latitude d600 battery, not only as a working , want to replace but also as a gaming machine, you need to invest more money. With a dedicated 3D graphics card , the prices now starting at around 650-700 € – that you get but even entry-level notebooks with cards like the Nvidia Geforce Go 7300 or 7400 or the ATI Mobility Radeon X1300 and X2300 .

664

Middle-class notebooks with graphics cards look like the Geforce Go 7600 is at around 820 € : the rich for most games – unless you call for current titles in highest picture quality at high resolutions.

What do the damage?

In our tests can be traced , in general, the processing and housing quality is no significant difference between cheap and expensive notebooks. Here the dividing line is rather between notebooks for home users and those for business customers , which usually sound processing , but are more expensive but at the same price or less facilities to offer

However, especially for cheap notebooks and its Acer laptop battery, the manufacturer is trying to pack a certain price point as much equipment as possible into the notebook. Since then it comes on every cent you can save on a component – which is less at the hardware can understand the technical data of the customer directly , such as processor clock speed or disk size. But manufacturers prefer to skimp on features, the quality (or lack of it ) proves only after long work such as display , housing or the battery.

On most laptops , you have two years warranty – no matter how expensive was the device. During this time you must therefore make a repair or availability of spare parts not really worried. The problem arises only later : The repair prices are based does not by the purchase price , but the cost of parts and labor. In a business notebook for 1500 euros worth after purchasing the product sometimes a costly repair, while a display is already changing the 600 -Euro -Notebook to economic total loss can be . But make sure the manufacturer has at all appropriate spare parts in stock – which the producers promise , although , in practice it is not always the case.

Conclusion

For many users, the computational speed is sufficient and well equipped bargain laptop . However, you must not forget that you are set to this benefit as long as you use the notebook , because the upgrade is more difficult than for the PC.

Most likely the low-cost laptops are good as a mobile addition to a secondary computer and inspiron e1705 battery ( games and multimedia – friendly) desktop system. Who is looking for a notebook for everyday work or mobile use , you must (still ) take more money in the hand.

How good are cheap laptops ?

Posted on June 29th, 2010 in battery maintain, battery review, battery tip, knowledge, laptop battery | Comments Off

Despite falling prices – even 500 € or 600 € are still a lot of money if you buy the wrong laptop. Therefore you should consider buying a cheap mobile computer well and apple a1185. Our buying guides brings clarity.

Everyone loves laptops. In Christmas 2006 , the Germans bought more laptops than PCs . And for the full year 2007 expected the industry association Bitkom that go in this country for the first time more laptops than PCs over the counter – Germany goes mobile.

The enormous growth in the notebook business a reason : Notebooks are getting cheaper for the same price or offer more features. For example, the first notebooks with Intel’s Core Duo was the cost to the market launch in early 2006 around € 1400 – with 80 GB hard drive, and an entry-level graphics card à la ATI Radeon Mobility X1400 . The current – generation Centrino Core 2 Duo launched for around € 1200 – including 200- GB hard drive, and Direct X 10 graphics card.

This price goes through all notebook segments: Currently you get a new notebook from about 400 € , there ’s dual core technology from around 530 € . And instead Gericom , Aldi , Lidl & Co., which began the price war in notebook PCs, providing worldwide now known notebook manufacturers like Acer laptop, HP laptop, Samsung laptop,and Toshiba laptop , the price battle in the discount rack.

Adequate performance is required

The main question before the laptop purchase is: What kind of performance you need at the moment and over the lifetime of the notebook ? The future security is important in a mobile host a larger role than with a PC. Unlike a desktop computer is the establishment and upgrading of hardware in notebooks that is difficult or impossible. While most have memory and disk exchange relatively simple – but you pay for example for
RAM that can fit in older notebook , usually about twice as much as for the corresponding PC RAM.

Who will , however, has bought a notebook with integrated graphics chipset and suddenly a powerful graphics card fit for 3D games , is also a chance like someone from a
Mononuclear – mobile wants to upgrade to a dual core CPU. That is why the recommendation : Quiet start shopping away from the more generous – unless you want to anyway , every two or three years
make new notebook or put the laptop next to the PC only as a secondary computer for mobile a well-defined area of responsibility.

The cheapest notebook ’s currently from 450-500 € (including Dell latitude d820 battery): For this you get an Intel Celeron M or AMD Mobile Sempron, the simplest variant of Vista Home Basic , 512 MB RAM and 80 GB hard drive . The processors are stripped down versions of the Core ( 2 ) Duo or Turion 64 X2, which have only a computational core, less L2 cache and a slower system clock.

Free Microsoft Guides to improve performance of windows vista

Posted on May 5th, 2010 in battery review, battery specs, knowledge, laptop battery | Comments Off

Microsoft has published a handbook with tuning tips for Windows Vista. The Windows Vista Performance and Tuning Guide is for anyone willing to download free. It provides end users and corporate clients advice on how to make Vista legs.

 55

The English-speaking guide for a faster Vista is called “Overview Series: Windows Vista Performance and Tuning” and is available as a PDF and as an XPS file. The download is large at 1.1 MB.

The Microsoft Advisor has tips on various ways of increasing performance summary:

  • Changes to the configuration, the response times and improve the starting behavior of the operating system
  • The correct use of the hardware
  • Increase the reliability and security of the system
  • Proper system monitoring to detect potential problems in advance

Most of the tips and tricks are ideal for end users of Windows Vista. But Microsoft keeps ready for enterprise customers, some tips to achieve a performance gain in a professional environment.

But before you do now a leap into the air and dreaming of a significant performance boost, you should first read the tips alone. Because Microsoft has not reinvented the wheel, but mostly already known and scattered across various Internet forums, and also from the PC World forth sufficiently known simply analyzed only clear advice. Some sounds almost trivial, such as the tip, turn off visual effects. Even something as valuable appears to point to the desktop search in Vista, the indexing system can be quite slow when the search is configured incorrectly.

Interesting for notebook users: Microsoft declares once more the different configuration options to achieve a balanced mix between performance and the longest possible battery life,like Ibm thinkpad t60 series battery.

Under the heading Hardware Tuning covered topics such as Windows ReadyBoost, which can be extended by the use of a suitable USB flash drive or a memory card the computer cache. Similarly, Windows will be presented ReadyDrive technology.

Another section deals with the starting performance of Vista and closely connected to the save Schlaf-/Ruhemodus (”Energy”). An important aspect of a possible fast acting Windows is shutting down unneeded services and programs running in the background and evidence so that system resources, even though they are not needed at all. Here you can simply by switching off some performance gain without anything missing. The User Account Control, one of the major new Vista features for enhanced safety, is also mentioned. Microsoft is in this context to the circumstances in which it makes sense to turn off UAC. Other topics are defragmenting and cleaning up the PC and the ongoing monitoring of system performance and function.

Positive: Microsoft does not content simply with a few key words, but explains exactly, in which menu item you must change the setting in Vista, such as to achieve the desired result. All steps are also illustrated with screenshots.

All in all, Microsoft reveals no secrets with this guide. His strength is simply that a lot of useful hints and Vista system maintenance tools are presented in summary and explained.

What is the best battery to use for a digital cellular phone? (B)

Posted on April 16th, 2010 in battery specs, digital camera battery, laptop battery, notebook review | Comments Off

In Figure 3, we study the relationship between energy density (ability) and the internal resistance of Li-Ion, NiMH and NiCd Lenovo thinkpad r61i series battery . To simplify the comparison, all battery packs are 3.6 volts.

Regarding the question of longevity, we also included the “best cycle time. It should be noted that periodic discharge cycles are needed for the cycle as provided for NiMH and NiCd Ibm thinkpad t42 battery. Successive rounds contributes very little to extend the performance of the Li-ion.

Even if overall energy needs of the digital phone is less than an equivalent analog phone, digital phone battery must be capable of delivering high current pulses that are often several times its own charge rate . Now for the rate of battery charge as expressed in loading rate C.

A 1 C discharge a battery charge rate is 500 mAh, is 500 mA. Comparatively, a 2 C discharge the same battery is 1000 mA. A GSN phone powered by a battery which draws 500 mA 1.5 A pulse, for example, charge the battery with a huge dump 3 C.

A landfill charge rate is 3 C is adequate for a battery having a very low reading of mO. However, old Li-ion and NiMH Ibm thinkpad r50 series battery are a problem, because reading mO these batteries increases with age and number of cycles.

* The internal wiring, contacts and protection circuits are taken into account. Readings vary depending on the loading elements, the charge status and the number of elements connected in series.

** The discharge is highest during the first 24 hours and decreases thereafter. Self-discharge increases with the age of the battery and high temperatures.

*** The length of life cycles is based on depth of discharge. A shallow discharge produced over a deep discharge cycles.

**** The life in cycles is based on the use and maintenance procedures. If we neglect to apply periodic full discharge cycles, the cycle can be reduced by a factor of three.

 

Figure 3: Characteristics of Li-Ion, NiMH and NiCd in terms of energy density of internal resistance, self-discharge and long life cycles

The performance can be improved by using a larger Ibm thinkpad r50e battery , also called extended battery pack. This extended battery pack is a little bigger and a little heavier, but offers a typical loading rate of about 1000 mAh or approximately twice a slim battery.
In terms of a loading rate C, 3 C discharge is reduced to 1.5C when using a battery of 1000 mAh instead of 500 mAh. The disadvantage of a large NiMH or NiCd is an increase of memory if, because of its greater capacity, the battery has not often allowed to discharge completely.

Some of the new generation phones are equipped with a DC-DC converter core, which reduces the demand for battery power. With this chip, a 1.5 A pulse can usually be reduced by half by stretching the peak current of the battery over a longer period. However, the downside is a loss of current of 10 to 12%. The higher capacity of the Ibm thinkpad r50p battery are also tested, but the strong current eruption occurring when the device is switched on, remains a problem. The size of the cell phone can also be a problem when adding a higher capacity battery.

What is the best battery for a digital cellular phone? (A)

When a consumer buys a replacement Ibm thinkpad t400 battery , it often has the choice between batteries of different chemical composition. In general, the new phones are equipped with NiMH and Li-ion, while older models use NiMH and NiCd. The seller may suggest a customer with a battery that the highest and recommend not to buy the NiCd, because of the memory effect. The client then chooses the NiMH battery slim, because it offers relatively high capacity for its small size and its price is reasonable.

When a consumer buys a replacement battery, it often has the choice between batteries of different chemical composition. In general, the new phones are equipped with NiMH and Li-ion, while older models use NiMH and NiCd. The seller may suggest a customer with a ibm thinkpad t60 battery that the highest and recommend not to buy the NiCd, because of the memory effect. The client then chooses the NiMH battery slim, because it offers relatively high capacity for its small size and its price is reasonable.

Even though it seems a good choice at first, the following analysis reveals that other chemical compositions can be much more effective. From the viewpoint of capacity, NiMH offers good value for the price but disappointing in terms of its life. Even if his performance is excellent when the battery is new, it declines rapidly after about 300 cycles due to a reduced capacity and increased internal resistance. In comparison, the NiCd can be used for more than 1000 cycles and internal resistance remains low. However, it is noted that the NiCd offers approximately 30% less capacity compared to NiMH.

The NiMH and NiCd are regarded as batteries to be carefully maintained, requiring discharge cycles to prevent memory. While advertising was first announced that the NiMH has no memory, NiCd and NiMH batteries are similarly affected by memory, because the formation of crystalline material resulting in the loss of capacity is generated mainly by the plate Nickel, a metal used in these two systems. The memory may not be as visible on the NiMH because of its shorter cycle time compared to the NiCd.

All nickel based battery should be fully discharged once a month. If such maintenance is not paid within a period of four or more months, there is a loss of capacity of up to one third. A full recovery becomes more difficult if one fails to perform this maintenance.

It is not recommended to discharge the Ibm thinkpad t60p series battery each time it must be loaded, as this uses the battery unnecessarily and shortens its life. Moreover, it is advisable not to leave a battery in a charger for an extended period. When the battery is not used, it will be stored or charged before use.

The Li-Ion Is it a better choice? Yes, for several applications. The Li-ion Ibm thinkpad z61e battery requires little maintenance and offers a high level of energy. It is lightweight and requires no periodic discharge. No adjustment is applied at low speed when the battery reaches full charge and the Li-ion battery can be left in most magazines until use.

It should be noted however that the Li-ion gradually loses its charge storage capacity, which is part of the aging of the battery, even if it is not used. For this reason, the Li-ion battery should not be stored for long periods, but must rather be rotations such as perishable foods, for example. Consumers should be aware of the date of manufacture when buying a replacement battery Li-ion. Unfortunately, this information is often encoded in the serial number and is not available to the user.

Even if the battery is the most expensive on the market, the Li-ion battery is ideal for those who use their cell phone every day. This Ibm thinkpad z61p battery can undergo approximately 1000 charge cycles and discharge, if they occur during the expected life, a period of approximately two years. Due to the aging effect, the Li-ion is not an economical solution for occasional users.

What is causing the premature failure of automotive batteries?

Posted on April 12th, 2010 in battery review, digital camera battery, laptop battery | Comments Off

A German manufacturer of luxury cars revealed that 400 SLI battery (Starting-Lighting-Ignition = start / Lighting / Ignition) was returned under warranty, 200 of them were working well and had no problem,such as sony vgp-bps2c battery. The low load and stratification are the most common causes of apparent failures. The automaker revealed that the problem is more common on large luxury cars with optional accessories that use a lot of energy on low-end models.

In Japan, the failures of batteries are the biggest complaint among new car owners. The average car is driven only for 13 km (8 miles) per day, mainly in cities with traffic congestion. Accordingly, the batteries will never fully charged and sulfation occurs. The batteries in cars in Japan are small and do not provide enough energy to start the engine and perform some rudimentary functions. North America may be protected from these battery problems, partly because driving distances are longer.

A good battery performance is important,like the Apple PowerBook G4 battery.because the problems blured customer satisfaction during the warranty period. Any required maintenance is recorded and the number published in trade magazines during this time. These data are of great importance among the potential buyers worldwide.
The malfunction of the battery is rarely caused by a defect in factory driving habits are the most common culprits. Too much electrical energy may be withdrawn for the distance traveled. Accordingly, the battery does not get its full load of regular maintenance, a requirement which is so important to the longevity of a battery-lead acid. According to a European manufacturer of automotive batteries to market leadership, the factory defaults are less than 7% of the total.

It is difficult to achieve a rapid and reliable assessment of failures of batteries. The most used ibm thinkpad x60 series battery testers simply take readings of the CCA (Cold Cranking Amps = Current cold start) and voltage. The capacity, which is the most important measure of a battery is not available. While making read-only CSF is relatively simple measure of the capacity is extremely complex devices that offer this feature are expensive. For this reason, most devices for measuring capacity are still based on the application of a full discharge and recharge. This procedure is commonly used in lab environment. The concept of time does not permit this for the servicing sector.

The Spectro CA-12 Cadex Electronics is the first in a series of ibm thinkpad x60s battery testers upscale, which is capable of measuring capacity, CCA and state of charge (SOC = state of charge) in a single test not disruptive. The technology is based on electrochemical impedance spectroscopy (EIS) multi-model. The system injects 24 excitation frequencies ranging from 20 to 2 000 Hz. The signals are regulated at 10mV / battery to remain within the linear portion of the battery voltage (thermal battery voltage) of lead-acid couple. This allows stable readings for small and large batteries.

The test lasts 30 seconds, during which about 40 million transactions are processed. A patented algorithm analyzes the data and final results are displayed in capacity, CCA and state of charge. The Spectro CA-12 for batteries is shown in Figure 1.

01

Figure 1: Spectro ™ CA-12, the tester of automotive batteries.
This device is the first in a series of battery testers that displays capacity, CCA and state of charge. A patent using electrochemical impedance spectroscopy multi-model has been given to Cadex Electronics.

The developed battery testers are designed to work in a range of preconfigured test,for one thing ,the Lenovo thinkpad r61e battery testers . Contrary to a photocopier that duplicates any document on the glass shelf, a battery tester fast high-end needs to know the battery type, nominal capacity, CCA and tension. In addition, a matrix is required and it is in relation to her readings are compared. These matrices include the family of current SLI sealed batteries, deep cycle batteries, those with glass fiber mat absorbent (GMTs = Absorbent Glass Mat), those with a spiral wound design and those used for gel-type chairs Wheel and people carriers. Matrices can also be developed to test the batteries containing lithium and nickel. The Spectro CA-12 is capable of storing 5 groups of matrices selectable menu to perform the maintenance of most common battery banks.

When will be available early next year, the Spectro CA-12 will include most usual matrices. The new matrices can be added while scanning the Lenovo thinkpad t61p series battery of the same model and different levels of performance using the CA-12 down a particular program. Before scanning, the batteries must be prepared by a program of discharge / charge set. Using the software “PC companion”, the data collected are sent home Cadex where engineers assemble the code and return a functional matrix to the user for download to the tester.
