How do I chaarge the battery on my lap top

1. connect the ac adapter from a known good power source.
2. plugin the battery to the laptop.
3. check bios if batt is recognize or performing normally (to do this turn on laptop keep tapping f2 to boot to the bios options)
4. just leave the laptop with the ac adapter connected and it will charge laptop automatically, just leave it for about 4 hours.

The battery is charged through the laptop so all you need is to have it plugged in to the wall. If you are not getting a charge still then that means you battery is defective. Is your pc older than 2 or 3 years old? If yes then you need a new battery my friend
