suggestions before you call Sony Customer Support. 

❑

Check that the computer is plugged into a power source and that it is turned 
on. Check that the power light is lit on the front panel of the computer.

❑

Confirm that a diskette is not in the diskette drive (unless you are using a 
bootable diskette).

❑

Confirm that the power cord and all cables are connected firmly, as described 
on the color poster.

❑

If you plugged the computer into a power strip or Universal Power 
Supply (UPS), make sure the power strip or UPS is turned on and working.

❑

Check that the display is plugged into a power source and turned on. Check 
that the brightness and contrast controls are adjusted correctly. See the 
manual that came with your display for details.
