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. 2. 3. Obtain the failing symptoms in as much detail as possible. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. Use the following table with the verified symptom to determine which page to go to.
Symptoms (Verified) Power failure (The power indicator does not go on or stay on). POST does not complete. No beep or error codes are indicated. POST detects an error and displayed messages on screen. Other symptoms (i.e. LCD display problems or others). Symptoms cannot be re-created (intermittent problems).
Go To Power System Check on page 69 Power-On Self-Test (POST) Error Message on page 72 Undetermined Problems on page 84 Error Message List on page 73 Power-On Self-Test (POST) Error Message on page 72 Use the customer-reported symptoms and go to Power-On Self-Test (POST) Error Message on page 72 Intermittent Problems on page 83 Undetermined Problems on page 84

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. 2. 3. Boot from the diagnostics diskette and start the diagnostics program. See if FDD Test is passed as the program runs to FDD Test. Follow the instructions in the message window.
If an error occurs with the internal diskette drive, reconnect the diskette connector on the system board. If the error still remains: 1. 2. 3. Reconnect the external diskette drive/DVD-ROM module. Replace the external diskette drive/CD-ROM module. Replace the main board.

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. If the symptom is not listed, see Undetermined Problems on page 84. The following lists the error messages that the BIOS displays on the screen and the error symptoms classified by function. NOTE: Most of the error messages occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. NOTE: If the system fails after you make changes in the BIOS Setup Utility menus, reset the computer, enter Setup and install Setup defaults or correct the error.

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. 2. 3. Run the advanced diagnostic test for the system board in loop mode at least 10 times. If no error is detected, do not replace any FRU. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.

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 69.): 1. 2. 3. Power-off the computer. Visually check them for damage. If any problems are found, replace the FRU. Remove or disconnect all of the following devices: Non-Acer devices Printer, mouse, and other external devices Battery pack Hard disk drive DIMM CD-ROM/Diskette drive Module PC Cards 4. 5. 6. 7. Power-on the computer. Determine if the problem has changed. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU: System board LCD assembly
