Troubleshooting
Å
WARNING: Only authorized technicians trained by HP should repair
this equipment. All troubleshooting and repair procedures are detailed
to allow only subassembly-/module-level repair. Because of the
complexity of the individual boards and subassemblies, do not attempt
to make repairs at the component level or modifications to any printed
wiring board. Improper repairs can create a safety hazard. Any
indication of component replacement or printed wiring board
modification may void any warranty or exchange allowances.
2.1 Computer Setup
Computer Setup is a preinstalled, ROM-based utility that can be
used even when the operating system is not working or will not
load. If the operating system is working, the computer restarts the
operating system after you exit Computer Setup.
✎
Pointing devices are not supported in Computer Setup; you
must use the keyboard to navigate and make selections.
The menu tables later in this chapter provide an overview of
Computer Setup options.
