Compaq Professional Workstation AP500 Maintenance and Service Guide
Troubleshooting Minor Problems
If minor hardware or software problems occur, refer to the following list for possible solutions
before running any of the diagnostic utilities.
■ Verify that the workstation is connected to a working grounded AC outlet.
■ Is the workstation turned on and the power light illuminated?
■ Check all cable connections. Be sure the connectors are seated properly.
■ Is the monitor turned on and the power light illuminated?
■ If the monitor is dim, turn up the brightness and contrast controls on the monitor.
■ After the system has started, press the Num Lock key repeatedly. If the Num Lock light
toggles on and off, the keyboard is OK.
■ Are all of the necessary device drivers installed?
■ Have all printer drivers been installed for each application?
■ Was a nonbootable diskette loaded in the diskette drive at powerup?
■ Was a bootable compact disc in the CD-ROM drive at powerup?
■ Check all switch and jumper settings.
■ Was Computer Setup run after installing options (memory, disk drives, expansion boards,
for example) and industry-standard architecture (ISA) boards?
