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. Obtain the failing symptoms in as much detail as possible.
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.
Memory check Memory errors might stop system operations, show error messages on the screen, or hang the system. Boot from the diagnostics diskette and start the doagmpstotics program (please refer to main board. Go to the diagnostic memory in the test items. Press F2 in the test items.
This helps you identify first the problem is on recharging or discharging. From Hardware: Power off the computer. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the following figure If the voltage is still less than 7.5 Vdc after recharging, replace the battery. To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer.
Power-on Self-Test Error Messages 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.
