Use the following procedure as a guide for computer problems.
NOTE: The diagnostic tests are intended to test this model (Aspire 1400 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.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 73
“Undetermined Problems” on page 81
POST detects an error and displayed messages 
on screen.“Error Message List” on page 74

displayed a FRU code.“System Diagnostic Diskette” on page 48
Other symptoms (i.e. LCD display problems or 
others).“Power-On Self-Test (POST) Error Message” on

Symptoms cannot be re-created (intermittent 
problems).Use the customer-reported symptoms and go to

							70Chapter 4
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 48 for details.
1.Boot from diagnostic program (see“System Diagnostic Diskette” on page 48
2.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/CD-ROM module.
2.Replace the external diskette drive/CD-ROM module.
3.Replace the main board.
External CD -ROM D rive Check
Do the following to isolate the problem to a controller, drive, or CD-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.Boot from the diagnostics diskette and start the diagnostics program (refer to “System Diagnostic 
Diskette” on page 48.
2.See if CD-ROM Test is passed when the program runs to CD-ROM Test.
3.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 external diskette drive/CD-ROM module.
2.Replace the external diskette drive/CD-ROM module.
3.Replace the main board. 
						

							Chapter 471
Keyboard or Auxiliary Input D evice 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 
48 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:
!Embedded numeric keypad
!External 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.
1.Boot from the diagnostics diskette and start the doagmpstotics program (please refer to “System 
Diagnostic Diskette” on page 48.
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.
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:
!“Check the Battery Pack” on page 72 
						

							72Chapter 4
Check the Battery Pack
To check the battery pack, do the following:
From Software:
1.Check out the Power Management in control Panel
2.In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total 
Battery Power Remaining are correct.
3.Repeat the steps 1 and 2, for both battery and adapter.
4.This helps you identify first the problem is on recharging or discharging.
From Hardware:
1.Power off the computer. 
2.Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the 
following figure
3.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. 
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 light up, replace the battery pack. If the charge indicator still does not light 
up, replace the DC/DC charger board. 
Touchpad Check
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:
1.After rebooting, run Tracking Pad PS2 Mode Driver. For example, run Syn touch driver.
2.Run utility with the PS/2 mouse function and check if the mouse is working.
3.If the the PS/2 mouse does not work, then check if the main board to switch board FPC is connected well.
4.If the main board to switch board FPC is connected well, then check if the FFC on touch pad PCB 
connects properly.
5.If the FFC on touch pad PCB connects properly, then check if LS851 JP1 Pin6=5V are pulese. If yes, then 
replace touch pad PCB. If no, then go to next step.
6.Replace switch board.
7.If the touch pad still does not work, then replace the FPC on Track Pad PCB.
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.

Power-O n 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 81.
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.
