The power management setting is not responding.

1 Close all open applications.
2 Restart the notebook by pressing the Ctrl+Alt+Delete keys
simultaneously. When the Windows Task Manager dialog box appears,
click Shut Down and then Turn Off from the drop-down menu.
Troubleshooting the LCD Screen
My LCD screen is blank.
❑ Check that the notebook is plugged into a power source and is turned on.
❑ Check that the power indicator on the notebook is on.
❑ Check that the battery pack is inserted properly and is charged.
❑ The notebook may be in LCD (Video) Standby mode. Press any key to
activate the screen.

mouse connector. See “Connecting a PS/2 External Mouse or Keyboard” in
the online User Guide for more information.
❑ If you are using an optional Sony USB mouse PCGA-UMS1 series, check
that the mouse is plugged into the USB port.

CD to reinstall the mouse drivers.
