Chapter 464 Check the Battery Pack To check the battery pack, do the following: From Software: 1.Check out the Power Options 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. 4.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. 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.After rebooting, run Touch pad/PS2 Mode Driver. 2.Run utility with the PS/2 mouse function and check if the mouse is working. 3.If 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 touch pad FPC connects to the main board properly. 5.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. 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. Display Check 1.Connect an external display to the computer’s external monitor port, the boot the computer. The computer can automatically detect the external display. Press Fn+ p to switch to the external display. 2.If the external display works fine, the internal LCD may be damaged. Then perform the following steps: Make sure the DDRRAM module is seated properly. Then run the diplay test again. If the problem still exists, go to next step. Replace the inverter board, then run the display test program again. If the problem still occurs, go on next step. Replace the LCD module with a new one then run the display test again. If the probelm still happens, continue next step.
65Chapter 4 Replace LCD/FL cable with a new one then execute the display diagnostic again. If the problem still occurs, continue next step. Replace the CPU with another of the same specifications. If the problems still occurs, go to next step. The main board may be damaged. Replace main board. 3.If the external monitor has the same problem as the internal monitor, the main board may be damaged. Please insert the diagnostic disk and run the display test program and go through the sub-steps under step 2. Sound Check To determine if the computer’s built-in speakers are functioning properly, perform the following steps. Before you start the steps below, adjust the speaker volume to an appropriate level. 1.Try different audio sources. For example, employ audio CD and ditital music file to determine whether the fault is in the speaker system or not. If not all sources have sound problem, the problem is in the source devices. If all have the same problem, continue next step. 2.Connect a set of earphone or external speakers. If these devices work fine, go to next step. If not, then the main board may be defective or damaged. Replace the main board. 3.Follow the disassembling steps in Chapter 3. Esure the speaker cable is firmly connected to the main board. If the speaker is still a malfunction, go on next step. 4.If the speakers do not sound properly, the speakers may be defective or damaged. Replace the speakers. If the problem still occurs, then replace the main board.
Chapter 466 Insyde MobilePro BIOS POST Beep Code and POST Messages 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 80. 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.
