Battery Talk

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of laptop battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of latitude D830 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the inspiron 1520 battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the VGP-BPS5 battery’s “charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the Satellite A100 battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.

5th System Info: An information tool for all

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:

Want to bet that you only use a part of Windows? Microsoft has hidden under the surface much more than you see in the start menu and desktop .

As a ” desktop “means the Microsoft Windows interface. What lying around openly on this desk , or directly accessible from the Start menu , the user usually know well and use it almost daily. But there are also a lot of useful tools in hidden drawers and secret compartments of the system and Sony VGP-BPS5A – you only have to open . The best is often hidden : we look at all the angles and bring real treasures to light. Not only users of Vista but Windows XP will be amazed by how much they can help with the secret tools to work. Many of the programs presented here can be operated only from the command line . Some also have a graphical interface , and they are really mature enough that they deserve a place in the Start menu.

1st Iexpress : CAB archives simply make himself

Start Iexpress (by simply typing ” Iexpress ” in the Start menu ) is part of the “Internet Explorer Administration Kit ” and is part of Internet Explorer. With the tool, you can transfer files to – summarized optional self-extracting install, or even themselves – CAB archives. The file selection you remember to request files in SED (Self Extracting Directive) in order to possibly use it later as a starting point.

How the tool: Select the first dialog “Create new Self Extraction Directive ” to create a new archive. In the next dialog, set the archive. For a self -install exe file, use the option “Extract files and run an installation command “. An EXE file, which can only extract itself, but not installed , you get to “Extract files only “. The third option , “Create compressed files only “, you produce a simple cab file. In the following dialogs you create when you create an EXE file, a package title, an individual installation and final certification, and optionally a text file with the license terms set . For a self-installing archive you must also specify an EXE or INF file that is started automatically after unpacking the archive. You can even specify a command to be executed thereafter.

2nd Eudcedit : Editor for custom signs

The Editor for custom character ” you create your own characters, you can use in all applications. Start it from Start , Run, eudcedit . You must be logged in XP as administrator on Vista to confirm the UAC prompt.

In the ” Select Code “, click on the box in the upper left corner and then click ” OK “. In the editor window, then draw with the mouse or your characters icon. With ” window, reference to ” you can open any existing characters , such as to copy it to completely or partially and then further process .

The editor , however, create completely new fonts , ie : TTF files, but only the files and EUDC.EUF EUDC.TTE in the Windows Fonts folder. The additional characters contained therein are in principle in all Windows applications and available for printing . However, it is not possible to put them on the font selection of a program. You have to click Start, Programs, Accessories , System Tools, Character Map go “- or “Start, Run, call charmap “- and choose after ” font “, select” All Fonts ( Custom characters) .

Use on other PCs: This requires you to install the files and EUDC.EUF EUDC.TTE there. Do not copy the files from Windows Explorer: If you try, you will receive an error message. Copy both files via command to a disk or network and on the target PC in the% windir % \ fonts “. Then start on the target PC Eudcedit , and close the program.

I have antivirus software, so I’m sure

Antivirus software is essential, but they alone will not protect against everything. Some antivirus products also block spam or phishing attempts still have spyware or other malware. Even if it has an antivirus software that protects against more than just viruses, you must also keep them up to date. New malware is discovered every day, so that antivirus software is only as good as they were at the last update. Moreover, it always takes a while to newly emerged threats have successfully saved in a database and the countermeasures have been updated to the anti-malware products. So they are not from the day zero protection against new attacks.

Security is only a problem when I use Windows

Microsoft had in recent years certainly get the biggest piece of cake attacker. This does not mean that other systems or applications are immune from attack. While Microsoft products are the most frequent target of attacks, but Linux and Mac OS X also have vulnerabilities that can be exploited. As alternative operating systems and web browsers have increasing numbers of users, they will slow more attractive targets. Currently, the attacks are aimed primarily at third-party software such as Adobe Reader to steal data from these systems.

My router has a built-in firewall, so my PC is protected

A firewall provides excellent protection against accidental, unauthorized access to your network and protect your computer and thinkpad t43 battery from a variety of hazards. However, hackers have figured out long ago that the fastest way is through the firewall ports that can pass the data ignored. In the default settings for most firewalls will be of normal traffic, waved through as Web data and e-mails, while only very few users the trouble of the firewall settings more accurate to take a close look at. Furthermore, many attacks these days run from web-based, for example via a phishing page, before you can not protect a firewall.

Since I visit only large and trusted sites, I have to be afraid of anything

You naturally increase the likelihood of your system infected by surfing to dodgy sites. But even large and well known sites are infiltrated now and then. For example, the pages of Apple, CNN, eBay, were Microsoft, Yahoo and even the FBI cracked by attackers and were able to collect information about users and malware to be installed on other computers and their ThinkPad x40 battery.

There are many laptop battery in the electronic market, a large number of substandard products into the market, including many original batteries counterfeit, take many potential to consumers. For non-professional consumers, we suggest the customer select the notebook battery following to the next tips:

1. Check packaging

Battery packaging should be sealed anti-static bags, anti-static foam lining, which is to protect the basic configuration of the VGP-BPS5 notebook battery.

Battery packaging should have a bar code serial code. Bar code is provided by the factory management of commodity standards to identify the authority logo.

2.check the appearance

Batteries should not be scratched or the appearance of the old sense, or readily available second-hand goods renovation as OEM battery.

Battery case should be clear parameters, performance, application of model identification.

Joints up and down the VGP-BPS5A battery cover should have no marks have been opened.

3. Check the official commitment to the protection of that and after-sale

Formal professional laptop battery grade qualified products cylindrical battery, since the date of the factory, there are bonds for one year warranty. If you can not have this commitment, then the use of batteries and other materials may not be the quality of very qualified sub-grade batteries but batteries. At present the market with large number of obsolete Japan, South Korea and the poor laptop battery conversion, this product may seem cheap products are actually huge profits, as well as the normal use of notebook computers much damage, the explosion will be serious personal injury caused to consumers.

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 .

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.

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.

Firmware

Similarly important as drivers and firmware updates, especially for optical drives. In fact , the burners are quality of custom CDs and DVDs increased. The reason: With each update , information provided to new blanks. There are built into laptops often specially adapted drives , we recommend the search of the notebook manufacturer side. For optical drives may be worth a look at the side of their providers .

Although Windows fixes and new device drivers are leading to significant improvements, functionality and speed are determined by the hardware used. Already for very little money can significantly increase the device performance . We show you how and where to make adjustments . Because notebooks differ greatly in part , you should always consult the instrument manual draw .

Battery exchange

The only component that can strongly with the time spring is the Apple laptop Battery. With its lively use performance decreases after a few months. Particularly cheap devices are affected. This pays off buying a second battery or a new energy donor. The best way to obtain a battery directly from the manufacturer . Thus both compatibility and quality are ensured. Furthermore, to the original manufacturer of many different versions , which differ in performance and size. Large batteries can store up to twice as much electricity , but they are for something out of the notebook chassis .

As a cheap alternative to auction houses such as manufacturers are recommended Ricardo and eBay. However, caution is warranted because a defective battery can cause damage to the entire notebook.

Installation: need a screw driver is not for the battery exchange. Using slides marked on the bottom of the lock is released and removed the Dell gd761. The insertion works the same way, with the lock not be solved even in most cases .

Memory upgrade

Most performance at the lowest price does additional memory , you buy the best in online shops . The purchase of the notebook and apple a1175 manufacturer pays rare because of massive higher prices. A doubling of one brings two gigabytes especially in Windows Vista very much, but under XP – especially if you often work with multiple open programs.

What type of RAM you need, you can see in the above- mentioned software SIW under Hardware / Memory. The old SD -RAM bars are not cheap even in online . This may be worth a look at online auction houses. Important: In any normal laptop RAM memory are used, but the smaller SO- DIMM format. Check before you buy, whether the speech in the product name of SO- DIMM.

Installation: The memory is usually located on the underside of the notebook and is easy to install on or off. In many cases , only one screw has to be removed to get access to the bolts. In part , the memory also lies under the keyboard , which must be removed first . To remove the bolt , release the lock on the corners and pull the RAM module out slowly. Install the new bolt in.

The typical end-discharge voltage for nickel-based laptop batteries is 1V/cell. At this voltage threshold of approximately 99% of the energy is used up and the terminal voltage begins to fall off rapidly if the discharge continues. Discharge below the cutoff should be avoided, especially under heavy load.

As the battery cells can not be perfectly controlled, creates a negative voltage potential, known as cell reversal, if the discharge is continuing unchecked. The more cells are connected in series, the greater the number is likely to be reversed cells.

Nickel-cadmium may be some reversals to tolerate the typically amount to approximately 0.2 V,. During this period of time is reversed the polarity of the positive electrode. Such a situation can persist only briefly, because the development of hydrogen at the positive electrode to a positive pressure and leads to a possible gas leak from the cell. If the Sony VGP-BPS2C cell for a prolonged period of Spannungsumpolung is exposed, both polarities are reversed and the cell is electrically short-circuited. Such an error can not be undone.

Some battery analyzers use a secondary discharge (regeneration) by performing a discharge of the battery up to a very low cut-off point. This device will monitor the discharge current in order to ensure that the maximum applicable current during the regeneration phase of a safety limit. If the reversal continues to develop, the discharge would be so small that no damage can occur. That cells are destroyed during the regeneration is only possible if these cells are either weak or old.

When Sony VGP-BPS2A cells are discharged with coefficients that are higher than 1C, the end-loaded or typically lowered to 0.9 V / cell. Thus, the voltage drop is compensated, which results from the internal resistance, consisting of wiring, circuit protection and contact transitions. A lower cut-off leads to better capacity values when the battery is discharged at lower temperatures.

Among all the nickel-cadmium VGP-BPS2 battery chemistries is the least affected by repeated full discharge cycles. Several thousand charge / discharge cycles are possible. Therefore, nickel-cadmium are working so well in tools and portable radios, where they are in constant use. Nickel-metal hydride is less durable in respect to repeated Tiefentladezyklen.

Lithium-ion is typically discharged to 3.0 V / cell. The versions of “spinel” and “Coke” can be discharged to 2.5 V / cell, and thus gain a few extra percentage points. As far as the device requires no special Battery, the devices are built for a cut-off point at 3.0 V / cell.

A discharge below 2.5 V / cell can switch the Sony VGP-BPS8 battery protection circuit that is active, it prevents future load with the normal charger. Such a battery can be saved with the help of the Boost program, which is present on the battery tray by Cadex 7000 Series analyzers.

Some lithium-ion VGP-BPS9 batteries contain a specially deep Spannungsabschaltepunkt, where the battery is put permanently out of service, if the cell voltage below 1.5 V / cell falls. A very strong discharge can lead to formation of a Kupfershunts, which can cause a partial or total short-circuit. The same can happen if the cell has a negative polarity and this situation persists for some time.

The manufacturers of lithium-ion batteries recommend a discharge depth at 80%. Repeated 100% discharge reduces the specific number of charge cycles. It is therefore recommended to charge lithium-ion batteries more often, rather as they were unloaded too deep. A periodic full discharge is needed because lithium-ion batteries are not subjected to the memory effect.

The recommended end-discharge voltage for lead-acid battery is 1.75 V / cell. The discharge does not follow the mostly flat curve of the chemistries of nickel or lithium base. Instead, have lead-acid batteries have a degree of voltage drop curve, with a steep drop toward the end of the discharge.

The VGP-BPS9/B life cycle of sealed lead-acid batteries is a direct dependence on the depth of discharge. The typical number of discharge / charge cycles at 25 ° C depending on the depth of discharge is:

· 150 – 200 cycles with a 100% depth of discharge (full discharge)

· 400 – 500 cycles with a 50% depth of discharge (partial discharge)

• 1,000 or more cycles with a depth of discharge of 30% (low discharge)

The lead-acid Dell laptop battery should not be discharged below 1.75 V / cell. Nor should it be stored in a discharged state. The cells of a non-charged lead-acid battery is sulfated, a circumstance that makes the battery useless if it only a few days are left in this state. You should be concerned that the open Klemmespannung always 2.10 V or more.

After used for a time, we can obviously feel that our computer getting more and more slow. The start time extend from 30 seconds to 1 minutes or more. When we use the computer to play game or wacthing video, the computer suddenly freeze. Then we should restart the laptop battery. Let me introduce some simple maintenance once or twice a month can make a difference in performance on all of his team.
