This section describes how to solve common problems you may 
encounter when using your computer. Many problems have simple 
solutions, so try these suggestions before you call Sony Online Support. 
My computer won’t start
Check that the computer is plugged into a power source and that it is 
turned on. Check that the power indicator on the front panel of the 
computer indicates that the power is on.
Check that the battery is inserted properly and that it is charged.
Make sure there is no diskette in the floppy disk drive.
Confirm that the AC adapter and all cables are connected firmly, as 
described in “Connecting Peripheral Devices” on page 33.
If you plugged the computer into a power strip or UPS, make sure the 
power strip or UPS is turned on and working.
If you are using an external display, check that it is plugged into a 
power source and turned on. Check that the brightness control is 
adjusted correctly. See the manual that came with your display for

for at least one hour and then turn on the computer.

remove the diskette, and then turn on the computer again. Confirm 
that Windows starts properly. If Windows still does not start, follow

When you reconnect devices, be sure to turn off the computer as described in “Shutting

result in data loss.
