Laptop Battery Repair

• First of all it is recommended to consult the internet to know what kind of battery could be repaired. But one needs to know a battery which is apt to leak should not be repaired, as it could be unsafe. But most batteries have the complex construction and therefore cannot be repaired at all. Some batteries can, but for that one should have specific tools. It is much cheaper and more wisely to buy a new one

Notebook Battery Removal

• Sometimes a damaged battery just needs a little calibration. Such work can be done in local laptop repair shops. But if a battery is really damaged, one should better throw it out to save money and nerves. Therefore one should be aware of the type of the battery when he is going to have repaired, or firstly to check the possibility of such repair in a store before buying
• But one must remember a laptop battery is one of the most important parts in a unit, and taking care of it is the quite rational thing

Extending Battery Power

• Whenever you are using your laptop near a power source, use the A/C adaptor. However, sometimes you will be forced to use your laptop with no access to a wall outlet, and the battery will run low. Here are three things you can do to extend the remaining power in the battery
• First, if your laptop processor features a power-save mode, switch over to power-save mode. This will slow the laptop by up to 50%, doubling battery life for that time period
• Second, turn off extraneous energy-sucking elements. The major power vampires in your laptop are the hard drive, the CD and DVD drives, any networking devices, and any excessively bright screen settings
• Third, you can double overall battery capacity by installing a second battery. Your laptop must have a universal bay in order to do this. All you have to do is remove the CD-ROM or floppy drive and put a battery in its place
