Charging the battery
Using your computer
Charging the battery
Connect the power adapter to your computer or tablet to charge the battery.
The battery gets charged when the computer or tablet is in use or turned
off. The internal circuitry of the battery prevents it from overcharging.
If the battery becomes too hot due to being in a hot
environment, it may not charge when you connect the power adapter.
Allow the battery to cool down for it to resume charging.
