CHAPTER
Troubleshooting
Hardware, software, or a combination of both can cause computer
problems. When you encounter any problem, it might be a typical
problem that can easily be solved.
This chapter tells you what actions to take when solving common
computer problems. It is divided into three sections:
Preliminary checklist
Solving common problems
Resetting the computer
Preliminary Checklist
Here are helpful hints to follow before you take further actions when you
encounter any problem:
Try to isolate which part of the computer is causing the problem.
Make sure that you turn on all peripheral devices before turning on
the computer.
If an external device has a problem, make sure that the cable
connections are correct and secure.
Make sure that the configuration information is properly set in the
SCU program.
Make sure that all the device drivers are correctly installed.
Make notes of your observations. Are there any messages on the
screen? Do any indicators light? Do you hear any beeps? Detailed
descriptions are useful to the service personnel when you need to
consult one for assistance.
If any problem persists after you follow the instructions in this chapter,
contact an authorized dealer for help.

Battery Problems
The battery does not charge (Battery Charge indicator does not
appear).
Make sure that the AC adapter is properly connected.
Make sure that the battery is not too hot – gets above 40oC (104oF) or
too cold – below 0oC (32oF). Allow time for the battery pack to
return to room temperature.
Make sure that the battery pack is installed correctly.
Make sure that the battery terminals are clean.
The operating time of a fully charged battery becomes shorter.
If you often partially recharge and discharge, the battery might not
be charged to its full potential. Initialize the battery to solve the
problem. (See “Initializing the Battery Pack” in Chapter 3 for
instructions.)
Make sure that power to the Tablet PC is off. If you use the Tablet
PC during recharging for more than 4 hours, the recharging will stop
no matter whether the battery has been fully charged or not. If this
happens, you can disconnect and then reconnect the AC adapter to
start the recharging again.
The battery operating time indicated by the battery meter does not
match the actual operating time.
The actual operating time can be different from the estimated time,
depending on how you are using the computer. If the actual
operating time is much less than the estimated time, initialize the
battery. (See “Initializing the Battery Pack” in Chapter 3 for
instructions.)
CD/DVD Drive Problems
The CD/DVD drive cannot read a CD.

drive’s manual eject hole and push firmly to release the tray.
Pull the tray out until fully extended, and then remove the CD.
Display Problems
Nothing appears on the screen.
If the power-on indicator is not on, check the electrical outlet, the
plugs and power cords.

discharged.
When you turn on the computer, it stops after POST.
Restart your computer.
The message “Operating system not found” appears on the screen
after you turn on the computer.
Make sure that there is no floppy disk in the floppy disk drive. If
there is, remove it and restart the system.

disk with a bootable one and press any key to continue booting.
If you are booting from the hard disk, make sure that there is no
floppy disk in the floppy disk drive. If there is, remove it and restart
the system.
If this message appears when you are booting from the hard disk,
insert a bootable disk in the floppy disk drive and check the
condition of the hard disk.
Other Problems

8-14
Correct the date and time via the operating system or SCU program.
After you have performed everything as described above and still
have the incorrect date and time every time you turn on the
computer, the RTC (Real-Time Clock) battery is at the end of its life.
Call an authorized dealer to replace the RTC battery.
Troubleshooting
Resetting the Computer
You may have to reset (reboot) your computer on some occasions when
an error occurs and the program you are using hangs up.
If the system operation seems to hang up, first wait. It is possible that the
system is processing data. Periodically check the hard disk drive in-use
indicator, if it flashes irregularly, the program may be accessing data and
preventing you from using the keyboard. If you are sure the operation has
stopped and you cannot use the “restart” function of the operating system,
reset the computer.
Reset the computer by any one of these method:
Press Ctrl+Alt+Del if you have an external keyboard connected.
If the above action does not work, turn off the system. Wait for at
least five seconds and turn it on again.
It the above does not work, insert a small rod, such as a straightened
paper clip, into the reset switch on the right side of the Tablet PC and
press firmly.
Reset Switch
CAUTION: Resetting will cause any unsaved data to be lost.
