    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. 
    To u c h p a d  C h e c k
    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.

    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 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.

    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.  
    						
    							81Aspire 1710
    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 70):
    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:
    TNon-Acer devices
    TPrinter, mouse, and other external devices
    TBattery pack
    THard disk drive
    TDIMM 
    TCD-ROM/Diskette drive Module
    TPC 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:
