VAIO Computer Quick Start
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 "Welcome" 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.
1 Insert the battery into the battery bay.
2 Connect the AC adapter to the computer. The computer automatically
charges the battery as long as the computer is using AC power.
The battery indicator blinks while the battery charges. The battery indicator stops
blinking when the battery is fully charged.
