How to Repair a Dead Laptop Battery

Shut down the power on your laptop and close the screen.
Locate the battery case on the underside of your laptop. The case will be a narrow rectangle shape, and be about as long as the width of the laptop.
Notice a lock/unlock sliding switch underneath your laptop. Usually there are two of these switches, each with a battery symbol, near each end of the battery case.
Grasp the laptop battery with your fingertips as you slide one of the switches to the unlock position. Now unlock the second sliding switch. The battery case should now come loose, which will allow you to remove it from the laptop.
Put the battery case in a large freezer bag. Make sure the bag is sealed completely and place it in your freezer for 12 hours.
Remove the bag from the freezer after 12 hours have passed. Take your laptop battery out of the freezer bag and allow it to completely return to room temperature. If condensation appears on the battery case, wipe it away with a small towel.
Slide the battery case back into the empty compartment on the bottom of your laptop. Make sure to lock the battery in place by moving both lock/unlock switches to the locked position.
Plug your laptop into a wall outlet, but do not turn it on. Allow the battery to charge for several hours.
Turn your laptop on and check the battery monitoring icon to see if the unit is fully charged. Usually the icon is on the bottom right side of the computer screen. Wait until the icon shows a full charge before proceeding.
Remove the wall outlet power and continue using your laptop, or let it sit with the power on, until the battery runs completely down. Now plug power back into the laptop and fully recharge your battery. Repeat this cycle of charging and discharging four times. After the fourth cycle you should notice your battery holding a charge for a much longer time than before.
