Use the following procedure as a guide for computer problems.
NOTE: The diagnostic tests are intended to test this model (TravelMate 530 series). Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses.
power cords are properly connected and secured;
there are no obvious shorts or opens;
there are no obviously burned or heated components;
all components appear normal.
4. After you perform visual inspection you can also verify the following:
ask the user if a password is registered and, if it is, ask him or her to enter the password.
verify with the customer that Wndows XP is installed on the hard disk. Operating systems that were not preinstalled by Acer can cause malfunction.
make sure all optional equipment is removed from the computer.
make sure the floppy disk is empty.
5. Use the following table with the verified symptom to determine which page to go to.
Power failure. (The power indicator does not go on or stay on.)
"Power System Check" on page 71.
POST does not complete. No beep or error codes are indicated.
"Power-On Self-Test (POST) Error Message" on page 75
"Undetermined Problems" on page 82
POST detects an error and displayed messages on screen.
"Error Message List" on page 76
The diagnostic test detected an error and displayed a FRU code.
"System Diagnostic Diskette" on page 46
Other symptoms (i.e. LCD display problems or others).
"Power-On Self-Test (POST) Error Message" on page 75
Symptoms cannot be re-created (intermittent problems).
Use the customer-reported symptoms and go to "Power-On Self-Test (POST) Error Message" on page 75
"Intermittent Problems" on page 81 "Undetermined Problems" on page 82
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.
External CD-ROM/DVD-ROM Drive Check
Do the following to isolate the problem to a controller, drive, or CD-ROM/DVD-ROM. Make sure that the CD-ROM does not have any label attached to it. The label can cause damage to the drive or can cause the drive to fail.
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 46 for more details.
If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a non-defective FRU:
If any of these devices do not work, reconnect the cable connector and repeat the failing operation.
Memory errors might stop system operations, show error messages on the screen, or hang the system. Currently, we do not provide memory test program. However, if you need to check memory but have no testing program or diagonositc utility at hand, please go to http://www.passmark.com to download the shareware "BurnIn Test V.3.0". You may test the memory with this program under Window XP environment.
NOTE: Make sure that the DIMM is fully installed into the connector. A loose connection can cause an error.
Power System Check
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
Check the Battery Pack
If the battery status indicator does not light up, remove the battery pack and let it return to room temperature. Re-install the battery pack.
If the charge indicator still does not emit, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.
If the touchpad doesn't work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU:
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 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.
Make sure the DDRRAM module is seated properly. Then run the diplay test again. If the problem still exists, go to next step.
Replace the inverter board, then run the display test program again. If the problem still occurs, go on next step.
Replace the LCD module with a new one then run the display test again. If the probelm still happens, continue next step.
Replace LCD/FL cable with a new one then execute the display diagnostic again. If the problem still occurs, continue next step.
Replace the CPU with another of the same specifications. If the problems still occurs, go to next step.
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.
To determine if the computer's built-in speakers are functioning properly, perform the following steps. Before you start the steps below, adjust the speaker volume to an appropriate level.
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 82.
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.
