■ chapter 2 trouble shooting

Your computer has been fully tested and complies with the

system specifications before shipping. However, incorrect
operations and/or mishandling may cause problems.

This chapter 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 chapter. Instead of returning the
computer and waiting for repair, you may easily solve the problems
by considering the following scenarios 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 computer.

 Check to see the power indicator of the computer is on.
 Check to see if your keyboard is operational by pressing and

holding any key.
 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, printer 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.
 Legacy peripheral are not 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 BIOS re-flash.
 Be sure the Quick Key Lockout Switch on the bottom of the
computer is not engaged; otherwise the quick keys will not work.

Hard Disk Problems

The hard disk drive does not work or is not recognizable -

 If you had just performed a hard disk upgrade, make sure
the hard drive connector is not loose and the hard disk drive is
also correctly seated. Remove it and reinsert it firmly, and
restart your PC. (Refer to Chapter 4 for details.)
 The new HDD may need to be partitioned and
reformatted. O/S and drivers will need to be re-installed as well.
 Check the hard disk indicator LED. When you access a
file, the LED lamp should light up momentarily.

 The new HDD may be defective or is not compatible.
 If your computer has been subjected to static electricity

or physical shock, you may have damaged the disk drive.

The hard drive is making abnormal whining noises -

 You should back up your files as soon as possible.
 Make sure the source of noise is indeed from the hard

drive and not the fan or other devices.

The hard disk drive has reached its capacity -

 Run Disk Cleanup utility in Windows. [Start > All
Programs > Accessories > System Tools > Disk Cleanup] The
system will prompt you for what to do.
 Archive files or programs that you had no longer used by
moving them to an alternative storage medium (floppy disk,
optical record-able disk, etc.) or uninstall programs that no
longer use.

speed up the performance. Check the program’s Online Help

for instructions on decreasing the cache size or on removing
temporary Internet files.
 Empty the Recycle Bin to create more disk space. When
you delete files, Windows saves them to the Recycle Bin.

The hard disk takes longer to read a file -

 If you have been using the drive for a period, the files
may be fragmented. Go to [Start > Programs > Accessories >
System Tools > Disk Defragmenter] to perform a disk
defragmentation. This operation may take a while.
 Interrupt requests or problems with other hardware
devices may have occupied the CPU and therefore slows down
the system performance.

The files are corrupted -

 Run the Error-checking utility in Windows to check the
HDD. Double-click My Computer. Right-click C: and select
Properties. Click Check Now in Error-checking in Tools.
