❑ This problem could be due to the battery pack not being installed properly. To solve this problem, turn off your computer
and remove the battery pack. Then reinstall the battery pack to the computer. For details, see Installing/Removing the
Battery Pack (page 22).
❑ If the problem persists, it means the installed battery pack is not compatible. Remove the battery pack and contact an
authorized Sony service/support center. To find the nearest center or agent, see Finding More about Your VAIO
Computer (page 5).
