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
considerable amount of 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.
To charge a battery
You can charge the battery when the computer is on or off. However, the battery will charge faster when the computer is
off. Charging the battery takes several hours. See your VAIO
®
Computer Specifications on the
page for the
approximate time needed to charge your battery.
Charge the battery at temperatures between 50°F and 80°F (10°C to 30°C). Lower temperatures require more time
to charge.

Insert the battery into the battery bay. If you want to charge more than one battery, insert the second battery
into the computer. See

for more information.
