3 Troubleshooting Your PC

If Your PC Has a Hardware Problem

If the Hard Disk Does Not Work

•Check that the disk power and data cables are correctly connected (refer to "Connecting IDE Devices", on page 27).

•Check that the hard disk drive has been “enabled” (refer to "Hardware Protection Submenu (Security group) in the HP Setup program—see "HP Setup Program", on page 66). There is also an option in the Setup program that lets you disable or enable boot on hard disk drive (refer to "Start-up Center Submenu (Security group)" in the HP Setup program—see "HP Setup Program", on page 66).

•Check that the hard disk drive has been detected (refer to "IDE Devices Submenu (Configuration group)" in the HP Setup program—see "HP Setup Program", on page 66).

•Check that the on-board Bus IDE is enabled if you are using the integrated IDE controller (refer to "IDE Devices Submenu (Configuration group)" in the HP Setup program—see "HP Setup Program", on page 66).

If the hard disk activity light does not flicker when the PC is accessing the hard disk drive:

•Check that the control panel connector is firmly attached to the system board.

•Check that the disk power and data cables are correctly connected.

If you are using a hard disk drive with a controller board (a SCSI hard disk, for example), the activity light does not flicker when the PC is accessing the hard disk drive
