If a newly replaced FRU does not correct the problem: If you have
reached this point of the check procedures and were instructed to replace a
FRU but doing so did not correct the problem, reinstall the original FRU and
go through "Start" again.
If you want to print a copy of a BIOS Setup Utility screen to an attached
printer, press Print Screen key, while the following screen is displayed.
PLEASE READ THE FOLLOWING:
Human Error is a cause for concern when applied to
check procedures. It exists in every first time set of
analysis procedures. It is therefore essential for
effective and time-efficient servicing that each stage of
every procedure be verified. (For example: When a
symptom is found, or when a symptom appears to have
been cured; the preceding steps should be repeated for
accuracy of analysis.)

To begin, note the following:
Disable the setting of “Quick Power-On Self Test” from BIOS Setup.
Disconnect all external cables and devices including speakers and
microphone from the system unit, except for the keyboard, mouse, and
monitor.
Power off the system unit before moving it or when replacing FRUs.
Remove all adapter cards, except for the factory-installed modem adapter
card and any other IBM Aptiva factory-installed adapter cards.
Disconnect any drives except:
3.5-in. diskette drive

IBM Aptiva factory-installed devices (such as a CD-ROM drive)
Make sure that all power cords and cables are connected properly.
Make sure that the monitor brightness and contrast controls are not turned
down.
Power on the system unit.
NOTE: Some monitors have a detachable system I/O signal cable between
the monitor and the system unit. In this case, check this signal cable
before replacing the unit. See “Monitor Port Signals” on page 5-15 for
