Try make a more descriptive title next time.

To charge the battery, use the laptop until it dies, then turn the laptop off, plug it in and leave it alone.

Once it's 95% or above, turn on the laptop, disconnect the charger, wait until it's 50%, then put the charger back in.

When 50% and plugged in, play a game and see if it charges back up to 95-100 again. If not, you have a problem.


Note, depending on your use of the laptop, it might take a while to charge.
