Using your notebook
Charging the battery pack
To charge the battery pack, proceed as follows:
1 Connect the AC adapter to the computer.
2 Insert the battery pack.
The computer automatically charges the battery (1) (the battery indicator (2) light flashes in a double
blink pattern as the battery charges). When the battery is 85% full, the battery indicator light turns off.
This process takes approximately one hour for the PCG-FX203/PCG-FX203K when the system is off. If the
system is on, it takes one and a half hour. To charge the battery completely, continue charging for an
additional hour.
There are two battery indicator lights on the computer:
1
2
When the battery is running out of power, both the battery and power indicators blink.
Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the
computer.
