If you suspect a power problem, see the appropriate power supply check in the following list:
T “Check the Power Adapter” on page 77
T “Check the Battery Pack” on page 78
Chapter 4 76
Page 86
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
Pin 1: +19 to +20.5V
Pin 2: 0V, Ground
1. If the voltage is not correct, replace the power adapter.
2. If the voltage is within the range, do the following:
T Replace the System board.
T If the problem is not corrected, see “Undetermined Problems” on page 91.
T If 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 power-on 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 Battery Pack” on page 78.
77 Aspire 1620
Page 87
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.
Touch pa d C h eck
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. Reconnect the touchpad cables.
2. Replace the touchpad.
3. Replace the system board.
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.
Chapter 4 78
Page 88
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 91.
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. Run the advanced diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRU.
3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
Chapter 4 90
Page 100
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 76):
1. Power-off the computer.
2. Visually check them for damage. If any problems are found, replace the FRU.
3. Remove or disconnect all of the following devices:
T Non-Acer devices
T Printer, mouse, and other external devices
T Battery pack
T Hard disk drive
T DIMM
T CD-ROM/Diskette drive Module
T 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 FRU.
7. If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU:
T System board
T LCD assembly
