Battery Pack
Can my computer enter Hibernate mode while running on battery power? Your computer can enter Hibernate mode while running on battery power, but some software programs and peripheral
devices prevent the system from entering Hibernate mode. If you are using a progr am that prevents the system from entering
Hibernate mode, save your data frequently to avoid losing data. See Using Hi bernate Mode (page 34) for information on
how you can manually activate Hibernate mode.
The battery care function is enabled to extend the life of your battery pack on the VAIO Control Center. Check the settings
on the VAIO Control Center.
❑This problem could be due to the battery pack not be ing installed properly. To solve this problem, turn off your computer
and push and hold the battery off button for three seconds with a thin , straight object (such as a paper clip). If this does
not solve the problem, remove the battery pack and install it once again.
If an extended battery pack is attached to the computer, turn off the computer and remove the extended battery pack. If
this does not solve the problem, push and hold the battery off button for three seconds. If the problem persists, remove
both battery packs and install them once again. For informatio n on how to install and remove the battery pack, see
Installing/Removing the Battery Pack (page 22).
❑If the problem persists, it means the installed battery pack is not com patible. 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).
