Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test only Acer products. Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. 3.
System Check Procedures External Diskette Drive Check Do the following to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required. NOTE: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device. 1. Boot from the diagnostics diskette and start the diagnostics program. 2.
If any of these devices do not work, reconnect the cable connector and repeat the failing operation. Memory check Memory errors might stop system operations, show error messages on the screen, or hang the system. 1. Boot from the diagnostics diskette and start the doagmpstotics program (please refer to main board. 2. Go to the diagnostic memory in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window.
Check the Power Adapter Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power adapter cable. See the following figure Pin 1: +19 to +20.5V Pin 2: 0V, Ground 1. If the voltage is not correct, replace the power adapter. 2. If the voltage is within the range, do the following: T Replace the System board. T If the problem is not corrected, see “Undetermined Problems” on page 82. T If the voltage is not correct, go to the next step.
Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Management in control Panel 2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the steps 1 and 2, for both battery and adapter. 4. This helps you identify first the problem is on recharging or discharging. From Hardware: 1. Power off the computer. 2.
Power-On Self-Test (POST) Error Message The POST error message index lists the error message and their possible causes. The most likely cause is listed first. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer.

Refresh battery (continue use battery until power off, then charge battery). Battery pack System board System hangs intermittently. Reconnect hard disk/CD-ROM drives. Hard disk connection board System board Peripheral-Related Symptoms Symptom / Error Action in Sequence System configuration does not match the installed devices.
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 advanced 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.
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 67.): 82 1.
