Chapter 462 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). 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.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.
63Chapter 4 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 75. 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.
