1Close all open programs.

2Click Start, the arrow next to the Lock button, and Restart.

3If your computer does not restart, press the Ctrl+Alt+Delete keys and click the arrow next to the Shut down button and Restart.

4If this procedure does not work, press and hold the power button until the computer turns off.

Turning off your computer with the power button may cause loss of unsaved data.

What should I do if the battery indicator is flashing and my computer does not start?

This issue could be due to the battery pack not being installed properly. To resolve this issue, turn off your computer and remove the battery pack. Then install the battery pack to the computer again. For details, see Installing the Battery Pack (page 23).

If the issue persists after performing the above, it means the installed battery pack is not compatible. Remove the battery pack and contact an authorized Sony Service Center. To find the nearest center or agent, see Sony Support Information (page 217).
