Troubleshooting BEFORE YOU BEGIN Before you start a troubleshooting job, be sure that: • • All peripheral devices are disconnected from the notebook. (They should be tested separately.) You have reviewed the safety precautions in the beginning of Chapter 3: Disassembly.
SYSTEM TROUBLESHOOTING CHART Use the following troubleshooting flow chart to locate the problem areas systematically. ! " TROUBLESHOOTING FLOWCHART FIG.
Troubleshooting PRE-POST ASSISTANT This section describes possible problems before the Power-On-Self-Test (POST) and ways to solve them. ! TABLE 4 – 1 PRE-POST PROBLEMS " 4 $ % & 4–4 pre-POST Possible Problems Possible Causes AC power LED fails The AC/DC adapter has malfunctioned. AC power & charge LEDs fail 1. The power board has failed. 2. The battery pack has malfunctioned or its connection to the power board is bad. 3. There is a short circuit in the system board.
AC POWER LED FAILS Under normal conditions, plugging in the AC/DC adapter makes the AC Power LED light up. If it fails to light up, it is possible that the AC/DC adapter is malfunctioning. If you think this is the case, try the following: • Make sure the power cord to the adapter is securely plugged into a properly grounded socket. • Make sure the adapter is completely connected to the adapter port on the computer. • Check the adapter’s contacts.
Troubleshooting AC POWER & CHARGE LEDS FAIL There may be other problems responsible for a system status LED’s failure to appear: • The power board failed. • The battery pack malfunctioned or its connection with the power board is bad. • There is a short circuit in the system board. Try the following troubleshooting procedures. CHECKING THE POWER BOARD ! A blown fuse or an incorrect output voltage on the power board may cause the system status LEDs’ malfunction.

Troubleshooting CHECKING THE BATTERY PACK AND ITS CABLING A malfunctioning battery pack or a bad connection between the battery pack and the power board may be the cause of the LEDs’ failure. CHECKING THE BATTERY PACK Whether the battery pack functions well or not can be checked by measuring the voltage across battery contacts BAT and GND. Figure 4-3, on page 4-7, shows the battery pack connector’s location and its associated fuse. Figure 4-4 below is the battery circuit diagram.
CHECKING THE CABLING If the battery pack is functioning properly, check if the measured voltage across pins 1 to 5 of connector CN4 on the power board (Fig. 4-3) is the same as the voltage measured for the battery pack. If the measured voltages are not the same, check if the fuse on the power board has been damaged. CHECKING THE SYSTEM BOARD Automatic short-circuit protection may have been activated by a short circuit occurring in the system.
Troubleshooting LCD SCREEN FAILURE TO DISPLAY The LCD screen’s inability to display may be due to any of the following problems: • There is bad connection between the LCD screen and the system board • The inverter board has malfunctioned • The LCD screen has malfunctioned CHECKING THE LCD TO SYSTEM BOARD CONNECTION A bad connection between the LCD screen and the system board may be the cause of the LCD screen’s failure to display.
CHECKING THE INVERTER BOARD Table 4-3 suggests areas where problems may occur and provides corresponding corrective actions. The component sites of the inverter board are shown in Figure 4-6. M Warning Inverter boards have highvoltage areas. To prevent electrical shock, do not touch the board when the system is on. Area to Check Action Fuse 1.0A (F1) Check the fuse and replace it if necessary. Connector CN1 Check if the voltages of all the pins of this connector are correct.
Troubleshooting CHECKING THE LCD SCREEN If you found no problems with the inverter board and its connection to the system board and the LCD lamp, and the LCD still doesn’t work, it is possible that the LCD screen itself may have malfunctioned. Replace the LCD screen to see if the problem can be solved. If the problem persists, send the notebook to the nearest service center for repair.
POST — T ESTING THE SYSTEM Each time the system is powered on, it automatically performs a Power-On-Self-Test (POST). The POST tests major system hardware and checks the system configuration. Error beeps and messages If the system can’t pass the POST, an error beep or message may be issued or displayed. This will indicate the problem with the system. If any major component malfunctions, send the notebook to the nearest service center for replacement.
Troubleshooting POST ERROR BEEPS & SCREEN MESSAGES Errors, fatal or non-fatal, can occur during the POST. All fatal errors and some non-fatal errors are communicated through a series of audible beeps. Table 4-4 below lists the error beep messages. Fatal errors do not allow the system to continue the boot process.

Troubleshooting SOUND OUTPUT FAILURE The notebook’s internal audio unit consists of the audio circuitry, built-in speakers, and built-in microphone. If the user cannot receive sound from the notebook’s internal speakers, it may be due to any of the following problems: • The audio chip is not configured with the supplied audio driver. • The volume control key combinations (Fn + F3, Fn + F5 & Fn + F6) are not properly adjusted. • The speaker cables are loose or frayed.
CHECKING THE SPEAKER CABLE If the speaker cables are not properly plugged into their connector, or they are frayed, the speakers may not work. First locate connector JINTSPK1 on the mainboard, then check if the speaker cables are loose or frayed. Replace each cable if it is frayed or plug it in if it is loose. LOCATING SPEAKER CONNECTOR IN THE BOTTOM COVER 1. Dissassemble the bottom cover. (See Chapter 3: Disassembly.) 2. The figure below shows how the speakers are connected.
Troubleshooting SUSPEND FUNCTION FAILURE Pressing the suspend key combination will enable the system to enter Suspend mode after few seconds. The power status LED will not light if the system is in Save to Disk mode. If the system can’t enter Suspend mode it may be because the Power Savings in your BIOS setup are not set properly. If any of the current settings are wrong, change them.
Appendix A Parts Lists A This appendix breaks down the notebook’s construction into a series of “exploded” illustrations. The component part numbers are indicated in the drawings. Note: The illustrations indicate the manufacturer’s part numbers. Your organization may use a different system, so be sure to cross-check any relevant documentation.
