NOTE: The diagnostic tests are intended to test this model (TravelMate 420 series). Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the failed symptoms in as much detail as possible. 2.
TM420.book Page 78 Monday, September 23, 2002 10:27 AM System Check Procedures External Diskette Drive Check Do the following steps 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. See “System Diagnostic Diskette” on page 52 for details. 1.
TM420.book Page 79 Monday, September 23, 2002 10:27 AM Keyboard or Auxiliary Input Device Check Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the main board. If the keyboard cable connection is correct, run the Keyboard Test. See “System Diagnostic Diskette” on page 52 for more details.
TM420.book Page 80 Monday, September 23, 2002 10:27 AM 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: 19V 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 main board. T If the problem is not corrected, see “Undetermined Problems” on page 90.
TM420.book Page 81 Monday, September 23, 2002 10:27 AM Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Options 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.
TM420.book Page 82 Monday, September 23, 2002 10:27 AM still occurs, continue next step. Replace the CPU with another of the same specifications. If the problems still occurs, go to next step. The main board may be damaged. Replace main board. 3. If the external monitor has the same problem as the internal monitor, the main board may be damaged. Please insert the diagnostic disk and run the display test program and go through the sub-steps under step 2.

TM420.book Page 89 Monday, September 23, 2002 10:27 AM 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 several times to isolate the problem. 2.
TM420.book Page 90 Monday, September 23, 2002 10:27 AM 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.
