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.
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 printed VAIO
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.
