To charge the battery pack
1
Connect the AC adapter to the computer. 
2
Insert the battery pack.
The computer automatically charges the battery (the battery indicator 
light flashes in a double-blink pattern as the battery charges). When the 
battery is 85 percent full, the battery indicator light turns off. This 
process takes approximately two hours. To charge the battery 
completely, continue charging for an additional hour. See “Displaying 
Detailed Battery Information” in the online manual Customizing Your 
VAIO® Notebook
