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.

NOTE: 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.
