Repair laptop batteries' mothods

October 24th, 2009

(A) cause damage to the battery

laptop computer battery life is longer, often dissatisfied with battery charge, and even show the battery has been damaged, concrete expression of the resistance is bigger, at charging voltage is increasing relatively quickly at both ends. So easy to charge control circuit has been judged already been filled, the capacity also falls. Since relatively large battery internal resistance, discharge voltage drop big, fast, so the system is easy to mistakenly believe that voltage is not enough electricity shortage. The discovery of relatively short battery life, should take appropriate measures.

(B) The battery refresh program to restore the battery discharge time

Big-brand notebooks have a battery refresh program, we can use it to repair the battery. For example: a IBM Thinkpad390/262650-based notebook computers, are fitted with nickel-metal hydride batteries (Ni-Mh) batteries, due to normal charge and discharge properly, leading to the battery discharge time is shorter, leaving less than 5 minutes, if the bring notebook computers to work, then it is very inconvenient, what methods can restore the battery discharge time?

In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the battery put it back in discharge time, specifically as follows.

(1) the use of AC adapters to the notebook computer, first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download software provided by IBM notebook computer batteries TP390/390e/390x refresh program.

(2) Restart the computer, press F8 key to enter boot menu and select safe DOS mode.

(3) to enter the directory where the file you just downloaded, the implementation of the battery refresh program isbr0lww, exe, reading a warning message, by asking you to insert a floppy disk, and then press the Enter key to the implementation of the self-extracting operation.

(4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Tips.

(5) Follow the prompts to unplug the AC power, the program will automatically pairs of Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.

(6) As the battery temperature is higher at this time should not immediately start, let the battery cool for a while, the plug in AC power.

(7) to guide the computer with the floppy disk, this Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes, press the Enter key.

(8) At this point, refresh program began to refresh the battery, the process quickly, when the return to DOS prompt A:> when that refresh has been completed.

(9) Turn off the computer, and recharge the battery until the green indicator light up.

(10) The above procedure repeated three times to get the best results.

Also, many battery pack lithium battery failure is the failure of a power-saving result of the core, this phenomenon can not be avoided. Because each section of the battery core properties can not be fully consistent with some of the quality of somewhat less long after the beginning of aging and the undermining of the whole (series after) the discharge curve. Interest and ability readers can try to open the battery pack, in the multimeter’s help, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product.

How Can An Online Computer Store Help You?

October 22nd, 2009

Buying a computer can sometimes be a tricky task, especially if you are not all that sure about computers. Some people choose to go to a computer store when they want to buy a new computer, but this can have its downsides as the moment you step into a computer store sales people will be trying to get you to make a purchase. This kind of behaviour can often upset people who just want to browse around a computer store to see what type of computer they would like to buy.

If you are put off by this happening to you when you visit a computer store, you should think about getting one of the online computer stores instead. Don’t be put off by the thought of not being able to see computers in front of you, using an online computer store can help you make your choice in many different ways, such as:

• An online computer store will have a massive choice of different computers available online and many of them will be at a massively reduced price – something that isn’t normally often an option when you go into a store to choose your new computer package from a regular computer store.

• An online computer store also has a great deal of information relating to all of the different computers on sale, if you see a computer you are interested in you just simply click into the product description to find out more about your computer. Regular stores tend not to have much in-depth information about their computers listed close instead they will just be a brief specification rundown.

• With an online computer store you can also get more information by e-mailing a member of the sales team who will get back to you as soon as possible – without being pushy. Many people find this approach much friendlier and customer focused as they are not railroaded into making a decision on the purchase of a new computer.

• Buying from an online computer store can sometimes help you to get extra software, hardware peripherals for your computer for the same price that you would expect to pay just for a basic computer package in a regular style. Doing this means that you get a whole lot more your money which no one would turn down.

• Delivery times from an online computer store are just as fast as buying from a regular store, if not faster. These stores have massive stocks of computers all waiting to be delivered to your home, if you want a computer fast, buy one from an online computer store and you will not be disappointed.

Anyone who is looking to buy a new computer really should think about buying from an online computer store. You get the best help and advice without feeling pushed into making a purchase and you could save a small fortune on the cost of your new computer and your new computer accessories.
