Charging a battery

You will need to charge the battery if battery power drops below 10 percent or
you have not used the battery for a long time. The lithium-ion battery supplied
with your computer may be recharged at any time, whether you wait until the
battery is completely or partially discharged. Charging a partially discharged
battery does not affect battery life. If you charge the battery and find that battery
power is still low, the battery may be reaching the end of its life, and you may
need to replace it.
✍
The battery supplied with your computer is not charged at the time of purchase.
