Chapter 471 Intermittent Problems Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1.Run the diagnostic test for the system board in loop mode at least 10 times. 2.If no error is detected, do not replace any FRU. 3.If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
72Chapter 4 Undetermined Problems The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU). NOTE: Verify that all attached devices are supported by the computer. NOTE: Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Check” on page 57): 1.Power-off the computer. 2.Visually check them for damage. If any problems are found, replace the FRU. 3.Remove or disconnect all of the following devices: TNon-Acer devices TPrinter, mouse, and other external devices TBattery pack THard disk drive TDIMM TPC Cards 4.Power-on the computer. 5.Determine if the problem has changed. 6.If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. 7.If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU: TSystem board TLCD assembly
Chapter 473 How to Build NAPP Master Hard Disc Drive CD to Disk Recovery 1.Prepare NAPP CD, Recovery CD and System CD. 2.Put NAPP CD into the optical drive. Then boot up the system. 3.The system will ask you if you want to build NAPP Master HDD. Please press any key to continue. 4.NAPP CD will start to preload the system, please click [Y]. 5.Select CD to Disk Revocery.
74Chapter 4 6.Put the Recovery CD to the optical drive. This step is to create image files to the system, you do not have to put the Recovery CD to the optical drive in order. Place one Recovery CD to the drive at one time till you finish all Recovery CDs. After you place the Recovery CD to the optical drive, you will see the display below.
