Chapter4 Troubleshooting
Use the following procedure as a guide for computer problems.

Note: The diagnostic tests are intended to test only Acer products. NonAcer 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. Note: To run the diagnostics, refer to "Running the Diagnostics"..
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 beeps, but no error codes are displayed. POST detected an error and displayed numeric error codes. The diagnostic test detected an error and displayed a Spare Part code. Other symptoms (such as LCD display problems). Symptoms cannot be re-created (intermittent problems). Go To "Power Systems CheckCheck". "Symptom-to-Spare Part Index", and then use the No Beep Symptoms table. "Symptom-to-Spare Part Index", and then use the Beep Symptoms table. "Symptom-to-Spare Part Index", and then use the Numeric Error Codes table. "Running the Diagnostics". "Symptom-to-Spare Part Index", and then use the Other Symptoms table. Use the customer-reported symptoms and go to "Symptom-to-Spare Part Index".

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.

Chapter 4

57

Do the following to select the test device. See "Running the Diagnostics" for details. 1. Boot from the diagnostics diskette and start the PQA program (please refer to "Running PQA Diagnostics Program"). 2. Go to the diagnostic Diskette Drive in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window. If an error occurs with the internal diskette drive, reconnector the connector on the Main board. If the error still remains: 1. 2. 3. 4. 5. Reconnector the diskette drive. Replace the diskette driver cable. Replace the diskette. Replace the IDE board Replace the Main board.

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 sub card. If the keyboard cable connection is correct, run the Keyboard Test. See "Running the Diagnostics" for details. If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a nondefective Spare Part: 1. Reconnector the keyboard cables. 2. Replace the keyboard. 3. Replace the Main board. The following auxiliary input devices are supported for this computer:
· Numeric keypad · External keyboard (with keyboard/mouse cable)

If any of these devices do not work, reconnector the cable connector and repeat the failing operation. If the problem does not recur, recheck the connector. If the problem is not corrected, replace the device and then the Main board.

Memory Check
DIMM cards are available for increasing memory capacity.
On Board (MB) 16 16 16 16 16 0 8 16 32 64 Slot 1 (MB) Total Memory (MB) 16 24 32 48 80

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 PQA program (please refer to "Running PQA Diagnostics Program". 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. Note: Make sure that the DIMM is fully installed into the connector. A loose connection can cause an error.

Chapter 4

59

Power System Check
To verify the symptom of the problem, power on the computer using each of the following power sources: 1. Remove the battery pack and diskette drive. 2. Connect the AC Adapter and check that power is supplied. 3. Disconnect the AC Adapter and install the charged battery pack; then check that power is supplied by the battery pack. If you suspect a power problem, see the appropriate power supply Check in the following list:
· "Checking the AC Adapter" · "Checking Operational Charging" · "Checking the Battery Pack"

Checking the AC Adapter:
· You are here because the computer fails only when the AC Adapter is

used:
· If the power problem occurs only when the port replicator is used,

replace the port replicator.
· If the power-on indicator does not turn on, check the power cord of the

AC Adapter for correct continuity and installation.
· If the operational charge does not work, go to "Checking Operational

Charging." 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure :

Pin 1 2

Voltage (Vdc) +16 Ground

If the voltage is not correct, replace the AC Adapter.

60

TravelMate 310 Service Guide

If the voltage is within the range, do the following:
· Replace the Main board. · If the problem is not corrected, go to "Undetermined Problems". · If the voltage is not correct, go to the next step. Note: An audible noise from the AC Adapter does not always indicate a defect.

Checking Operational Charging: To check operational charging, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the Main board. Then reinstall the battery pack. If the reinstalled battery pack is not charged, go to the next section.

Checking the Battery Pack:
Battery charging will not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life. Do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery first and last grid. If the voltage is still less than +7.5 Vdc after recharging, replace the battery.

TouchPad Check
If the TouchPad does not work, check the configuration in the TouchPad BIOS program. If the configuration of the TouchPad is disabled, select Enable to enable it. If this does not correct the TouchPad problem, continue with the following. After you use the TouchPad, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure

Chapter 4

61

is applied to the TouchPad pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. If a click button problem or the pointing stick problem occurs, do the following: 1. Boot from the diagnostics diskette and start the PQA program (please refer to "Running PQA Diagnostics Program". 2. Go to the diagnostic Pointing Dev. in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window. If either the pointing stick or the click button do not work, do the following actions one at a time to correct the problem. Do not replace a nondefective Spare Part: 1. Reconnector the TouchPad cables. 2. Replace the TouchPad FPC. 3. Replace the TouchPad.

62

TravelMate 310 Service Guide

Symptom-to-Spare Part Index
The symptom-to-Spare Part index lists the symptoms and errors and their possible causes. The most likely cause is listed first.

Note: Perform the Spare Part replacement or actions in the sequence shown in the "Spare Part/Action" columns. If a Spare Part replacement did not solve the problem, put the original part back in the computer. Do not replace a nondefective Spare Part.
This index can also help you determine the next possible Spare Part to be replaced when servicing a computer. Numeric error codes show the errors detected in POST or system operation. If no codes are available, use narrative symptoms. If the symptom is not listed, go to "Undetermined Problems" .

Numeric Error Codes
The following is a list of the message that the BIOS can display. Most of them 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. Following the list are explanations of the messages and remedies for reported problem.

Note: If the system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error

Serial or parallel port device problems.

Note: If you cannot find a symptom or an error in this list and the problem remains, see "Undetermined Problems".

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. Spare Part 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 Main board in loop mode at least 10 times. 2. If no error is detected, do not replace any Spare Part. 3. If any error is detected, replace the Spare Part shown by the Spare Part code. Rerun the test to verify that no more errors exist.

Undetermined Problems
You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or

the system is inoperative. Follow these procedures to isolate the failing Spare Part (do not isolate nondefective Spare Part).

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 Systems Check"): 1. Power off the computer. 2. Visually check them for damage. If any problems are found, replace the Spare Part. 3. Remove or disconnect all of the following devices:
a. Non-Acer devices b. Devices attached to the port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. DIMM g. Diskette drive h. PC 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 Spare Part. 7. If the problem remains, replace the following Spare Part one at a time. Do not replace a nondefective Spare Part:
a. Main board b. LCD assembly
