Preface
Before using this information and the product it supports, please read the following general information. 1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION decided for Acer's "global" product offering. To better fit local market requirements and enhance product competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g. add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered in this generic service guide. In such cases, please contact your regional offices or the responsible personnel/channel to provide you with further technical details. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information available on your regional web or channel. If, for whatever reason, a part number change is made, it will not be noted in the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFERENT part number code to those given in the FRU list of this printed Service Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and service of customer machines.

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 detects an error and displayed messages on screen. The diagnostic test detected an error and displayed a FRU code. Other symptoms (i.e. LCD display problems or others). Symptoms cannot be re-created (intermittent problems).

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 49 for details. 1. 2. 3. 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. Boot from diagnostic program (seeSystem Diagnostic Diskette on page 49) If an error occurs with the internal diskette drive, reconnect the diskette connector on the main board.
If the error still remains: 1. 2. 3. Reconnect the external diskette drive module. Replace the external diskette drive module. 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 CDROM 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. Make sure that the appropriate driver has been installed on the computer for the CD/DVD drive. Boot from the diagnostics diskette and start the diagnostics program (refer to System Diagnostic Diskette on page 49.) See if CD-ROM Test is passed when the program runs to CD-ROM/DVD-ROM Test. Follow the instructions in the message window.

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: 19V Pin 2: 0V, Ground
If the voltage is not correct, replace the power adapter. If the voltage is within the range, do the following: Replace the main board. If the problem is not corrected, see Undetermined Problems on page 84.
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. 4. If the DC-IN indicator does not light up, check the power cord of the power adapter for correct continuity and installation. If the operational charge does not work, see Check the Power Adapter on page 74.

Check the Battery Pack

To check the battery pack, do the following: From Software: 1. 2. 3. 4. Check out the Power Options in control Panel In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. Repeat the steps 1 and 2, for both battery and adapter. This helps you identify first the problem is on recharging or discharging.
From Hardware: 1. 2. 3. 4. Power off the computer. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). If the voltage is still less than 7.5 Vdc after recharging, replace the battery. If the voltage is within the normal range, run the diagnostic program.
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 emit, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.

Touchpad Check

If the touchpad doesnt work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU: 1. 2. 3. 4. 5. 6. 7. After rebooting, run Touch pad/PS2 Mode Driver. Run utility with the PS/2 mouse function and check if the mouse is working. If the PS/2 mouse does not work, then check if the main board to switch board FPC is connected well. If the main board to switch board FPC is connected well, then check if the touch pad FPC connects to the main board properly. If there is still an error after you have connected the touch pad FPC to the main board properly, then replace the touch pad or touch pad FPC. The touch pad or touch pad FPC may be damaged. Replace switch board. If the touch pad still does not work, then replace the FPC on Track Pad PCB.

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 84. 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.
