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.
1.Obtain the failed 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.
3.If any problem occurs, you can perform visual inspection before you fellow this chapter’s instructions. You 
can check the following:
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.
Symptoms (Verified)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

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 46 for details.
1.The FDD heads can become dirty over time, affecting their performance. Use an FDD cleaning kit to clean 
the heads. If the FDD still does not function properly after cleaning, go to next step.
2.Boot from diagnostic program (see“System Diagnostic Diskette” on page 46)
3.If an error occurs with the internal diskette drive, reconnect the diskette connector on the main board.
If the error still remains:
1.Reconnect the external diskette drive module.
2.Replace the external diskette drive module.
3.Replace the main board.
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.
Do the following to select the test device:
1.Insert an audio CD into the CD/DVD drive. If the CD/DVD drive can read the data from the audio CD. The 
drive does not have problem, then go to next step. If the CD/DVD LED on the front panel does not emit 
light as it read the data from the audio CD, then go to next step. However, if the CD/DVD drive can not 
read data from the audio CD, you may need to clean the CD/DVD drive with a CD/DVD drive cleaning 
disk.
2.Make sure that the appropriate driver has been installed on the computer for the CD/DVD drive.
3.Boot from the diagnostics diskette and start the diagnostics program (refer to “System Diagnostic 
Diskette” on page 46.)
4.See if CD-ROM Test is passed when the program runs to CD-ROM/DVD-ROM Test.
5.Follow the instructions in the message window.
If an error occurs, reconnect the connector on the main board. If the error still remains:
1.Reconnect the CD-ROM/DVD-ROM module.
2.Replace the CD-ROM/DVD-ROM module.
3.Replace the main board. 
						

							Chapter 471
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:
1.Reconnect the keyboard cables.
2.Replace the keyboard.
3.Replace the main board.
The following auxiliary input devices are supported by this computer:
TEmbedded Numeric Keypad
TExternal keyboard
If any of these devices do not work, reconnect the cable connector and repeat the failing operation.
Memory Check
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
To verify the symptom of the problem, power on the computer using each of the following power sources:
1.Remove the battery pack.
2.Connect the power adapter and check that power is supplied.
3.Disconnect the power 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:
T“Check the Power Adapter” on page 72
T“Check the Battery Pack” on page 73 
						

							72Chapter 4
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
1.If the voltage is not correct, replace the power adapter.
2.If the voltage is within the range, do the following:
TReplace the main board.
TIf the problem is not corrected, see “Undetermined Problems” on page 82.
TIf the voltage is not correct, go to the next step.
NOTE: An audible noise from the power adapter does not always indicate a defect.
3.If the DC-IN indicator does not light up, check the power cord of the power adapter for correct continuity 
and installation.
4.If the operational charge does not work, see “Check the Power Adapter” on page 72.
