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 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.) 001 - START 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.
