Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test only our company’s products. Other brand’s products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to re-create the failure by running the diagnostic te 3. st or by repeating the same operation. 4.
System Check Procedures Power System Check To verify the symptom of the problem, power on the computer using each of the following power sources: 1. Remove the battery pack. 2. Connect the power adapter and check that power is supplied. 3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by the battery pack.
7 5 3 1 3. 6 4 2 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.
Phoenix BIOS Error Code Messages The following are the list of messages that Phoenix BIOs can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., and the amount of memory installed. Others may indicate a porblem with a device, such as the way it has been configured. The following lists the explanation of the messages and remedies for reported problems.

One or more I20 Block Storage Devices were excluded from the Setup Boot Menu. There was not enough room in the IPL table to display all installed I2O bloc storage devices.
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.
Error Message List Error Messages Memory size found by POST differed from CMOS FRU/Action in Sequence Run “Load Default Settings” in BIOS Setup Utility.
Index of Symptom-to-FRU Error Message Error Message List No beep Error Messages No beep, power-on indicator turns off and LCD is blank.

Action in Sequence modem board Main Board NOTE: If you cannot find a symptom or an error in this list and the problem remains, see “Undetermined Problems” on page 95.
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 main board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRU. 3.
