Machine Disassembly and Replacement

This chapter contains step-by-step procedures on how to disassemble the notebook computer for maintenance and troubleshooting. To disassemble the computer, you need the following tools Wrist grounding strap and conductive mat for preventing electrostatic discharge Flat-bladed screwdriver or plastic stick NOTE The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components.

Check the Battery Pack

To check the battery pack, do the following 2. Remove the battery pack and measure the voltage between battery terminals 2(+) and 7(ground). See the following figure 3. If the voltage is still less than 8.0 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...

Indicators

The computer has six easy-to-read status indicators (LEDs) under the display screen. The Power and Standby indicators are visible even when you close the display cover so you can see the status of the computer while the cover is closed. Blinks when a battery-low condition occurs. Lights when the computer enters Standby mode. Lights when the floppy drive, hard disk or CD-ROM drive or DVD-ROM drive is active. Lights when the battery is being charged. Lights when Numeric Lock is activated.

Index of Error Message

The symptom-to-FRU index lists the symptoms and errors and their possible causes. The most likely cause is 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 69....

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,...
