In this section, you will learn how to solve common hardware and software problems.



Your notebook has been fully tested and complies with the system specifications before shipping. However, incorrect operations and/or mishandling during shipment may cause problems.

This section provides a reference for identifying and correcting common hardware and software problems that you may encounter.

When you encounter a problem, you should first try to go through the recommendations in this section. Instead of returning the notebook and waiting for repair, you may easily solve the problems by considering the following problems and possible solutions. If the error continues, contact your reseller for service information.

Before taking further actions, consider the following suggestions:

Check to see if the problem persists when all the external devices are removed.

Check to see that the green light indicator on the AC adapter is lit.

Check to see the power cord is properly plugged to the wall outlet and to the notebook.

Check to see the power indicator of the notebook is on.

Check the brightness control on the keyboard if the LCD display appears dim.

Check to see if your keyboard is operational by pressing and holding any key. An audible beep indicates the keyboard is functioning correctly.

Check for any incorrect or loose cable connections.

Make sure the latches on the connectors latch securely on to the receptor end.



Be sure you have not performed an incorrect setting on the hardware devices in the BIOS Setup utility. A faulty setting may cause the system to misbehave. If you are not sure of the changes you made, try to restore all the settings to factory defaults.

Be sure all the device drivers are installed properly. For example, without the audio driver properly installed, the speakers and microphone will not work.

If external devices such as USB camera, scanner, SCSI card do not function correctly when connected to the system, it is usually the device’s own problem. Consult the device’s manufacturer first.

Some software programs, which have not gone through rigorous coding and testing, may cause problems during your routine use. Consult the software vendor for problem solving.

Not all peripheral are plug-and-play capable. You need to restart the system with these devices powered up and connected first.

Be sure to go to BIOS SETUP and load DEFAULT

SETTING after any BI OS updated.

Excessive line noise might cause the connection to be dropped. To check this, put the regular phone handset on the line and placing a phone call. If you do hear abnormal noise, try to make the modem connection with a different line or contact your local telephony company for service.

Make sure the RJ-11 cable (the one that goes from the modem to the telephone line) is firmly connected to the modem's RJ-11 jack and the telephone line socket.

Check the serial port settings. Make sure the hardware and software are referring to the same COM port.

Try a different receiver number and see if the problem persists.

Be sure the line has a dial tone.



Network Adapter Problems

The Ethernet adapter does not work –

Go to [Start > Settings > Control Panel > System >

Hardware > Device Manager]. Double-click on Network

Adapters and check if SiS 900 PCI Fast Ethernet

Adapter appears as one of the adapters. If it does not exist, Windows has not detected the SiS Ethernet adapter or the device driver has not been installed properly. If there is a yellow mark or red cross on the

SiS network adapter, there may be a device or resource conflict. Replace / update the device driver from the factory CD-ROM disk or consult Windows manual on how to solve this problem.

Make sure the physical connections on both ends of the cable are good.

The hub or concentrator may not be working properly.

Check to see if other workstations connected to the same hub or concentrator are working.

100Mbps transmission mode –

Make sure the hub you are using supports 100Mbps operation.

Make sure that your RJ-45 cable meets the 100Base-TX requirements.

Make sure the Ethernet cable is connected to the hub‘s socket that supports 100Base-TX mode. The hub may have both 100Base-TX and 100Base-T sockets.



Performance Problems

The notebook becomes hot -

In a 35°C environment, the notebook’s bottom case is expected to reach 50 degrees.

Make sure the air vents are not blocked.

If the fan does not seem to be working at high temperature (50 degrees Celsius and up), contact the service center.

Certain programs that are processor-intensive may increase the notebook temperature to a degree where the notebook automatically slows down its CPU clock to protect itself from thermal damage.

The program appears stopped or runs very slowly -

Press CTRL+ALT+DEL to see if an application is still responding.

Restart the notebook.

This may be normal for Windows when it is processing other CPU-intensive programs in the background.

You may be running too many applications. Try to close some applications or increase system memory for higher performance.

The processor may have been overheated due to the system’s inability to regulate its internal heat. Make sure the notebook’s ventilation grills are not blocked.



Power, Start, and Battery Problems

The notebook powers down as soon as it is powered on -

Battery power may be extremely low. The circuitry prevents a complete power drain, which is not intended for Lithium Ion batteries. Use the adapter to charge it for several hours before trying again.

The notebook beeps intermittently -

When battery charge is low, an audible beep warns you.

Press Fn+F3 to turn off the warning beep, if desired.

The battery life gets shorter and shorter -

The battery has a finite life of about 500 charge cycles. If your battery is over one or two years old, it may be time to have it replaced.

Try a higher power saving setting in the BIOS or in the

Windows Power Management.

The battery does not charge -

Make sure the AC adapter is plugged into a valid power source.

The battery charge indicator LED on the notebook should be lit when you plug in the AC adapter.

Make sure the battery module is fully inserted in its bay; make sure the battery latch is in locked position.

If the battery is operating at a very high temperature, it may not charge.



Printing Problems

The printer does not print -

Make sure the cable connection is secured and the printer is powered up.

Run the printer self test to see if it reports any problem.

Check if the printer displays any error messages. A paper jam may have occurred.

Make sure you have already installed the printer driver.

Most printer (using parallel or serial port) problems are software-related. Consult Windows on-line help or contact the printer vendor for assistance.

Try rebooting the system with the printer powered up and connected first.

The printer does not print what’s on the screen -

The information displayed on the screen may not exactly be the same as what is printed.

If the printer print extra and strange symbols, it is the result of the cache (garbage) in the printer memory buffer. Cancel all the printer tasks and toggle off the printer power switch to clear up the memory buffer. Then, turn the printer back online and print again.

Make sure you install the correct printer driver.

The printer does not respond to infrared communication


See Infrared Problems listed elsewhere in this section.
