HardwareIf you cannot find a software problem, you should
then check the setup and configuration of your
hardware. First run through the items in the
preliminary checklist as described previously
then, if you still cannot correct the problem, try to
identify the source - the next section provides
checklists for individual components and
peripherals.
Before using a peripheral device or application software that is not an
authorized Toshiba part or product, make sure the device or software can
be used with your computer. Use of incompatible devices may cause injury
or may damage your computer.
If something goes wrong
Your program stops responding
If you are working with a program that suddenly freezes all operations,
chances are the program has stopped responding. You can exit the failed
program without shutting down the operating system or closing other
programs.
To close a program that has stopped responding:
1. Press CTRL, ALT , and  DEL simultaneously (once), then click  Start 
Task Manager . The Windows®
 Task Manager window appears.
2. Click the  Applications tab. If a program has stopped responding, the
words "not responding" appear beside its name in the list.
3. Select the program you want to close, then click  End Task. Closing
the failed program should allow you to continue working. If it does not,
continue with the next step.
4. Close the remaining programs one by one by selecting the program name, then  End Task. Closing all programs should allow you to
continue working. If it does not, power off your computer and then
restart it.
The computer will not start
Make sure you attached the AC adaptor and power cord/cable properly or
installed a charged battery.
If you are using the AC adaptor, check that the wall outlet is working by
plugging in another device, such as a lamp.
Verify that the computer is on by looking at the ON/OFF indicator.
If the indicator is glowing, the computer is on. Also, try turning the computer
off and then on.
If you are using an AC adaptor, verify that the computer is receiving power
from the external power source by looking at the AC power light. If the

Hardware and system checklist This section discusses problems caused by your computer’s hardware or
attached peripherals. Basic problems may occur in the following areas:
Power
Keyboard
Internal display panel
Hard disk drive
Memory media card
Touch Pad
USB device
Sound system
External monitor
LAN
Wireless LAN
Bluetooth
Power
When the computer is not plugged into an AC power outlet, the battery
pack is the primary power source. However, your computer also has a
number of other power resources, including an intelligent power supply and
a Real Time Clock (RTC) battery, all of which are interrelated with any one
having the ability to produce apparent power problems.
Overheating power down
If the processor's temperature reaches an unacceptably high level with
either setting, the computer will automatically shuts down to prevent any
damage - in this instance all unsaved data in memory will be lost.
AC power
If you have trouble turning on the computer with the AC adaptor connected
you should check the status of the  DC IN/Battery indicator. Please refer to
Chapter 5,  Power and Power-Up Modes  for further information.
ProblemProcedure
AC adaptor doesn’t
power the computerCheck the connections to make sure that the
power cord/adaptor is firmly connected to the
computer and a working power outlet.
Check the condition of the cord and terminals. If
the cord is frayed or damaged it should be
replaced, while if the terminals are soiled, they
should be cleaned with a clean cotton cloth.
If the AC adaptor still does not power the
computer, you should contact your reseller, dealer
or service provider.

Battery
If you suspect a problem with the battery, you should check the status of
the DC IN/Battery  indicator.
ProblemProcedure
Battery doesn’t
power the computerThe battery may be discharged - connect the AC
adaptor to recharge the battery.
Battery doesn’t
charge when the AC
adaptor is attachedIf the battery is completely discharged, it will not
begin charging immediately, in these instances you
should wait a few minutes before trying again. If
the battery still does not charge, you should check
that the power outlet the AC adaptor is connected
to is supplying power - this can be tested by
plugging another appliance into it.
Check whether the battery is hot or cold to the
touch - if so, it will not charge properly and should
be allowed to reach room temperature before you
try again.
Unplug the AC adaptor and remove the battery to
make sure its connecting terminals are clean - if
necessary wipe them with a soft dry cloth lightly
dipped in alcohol.
Connect the AC adaptor and replace the battery,
taking care to ensure that it is securely seated in
the computer.
Check the DC IN/Battery  indicator - if it does not
glow, allow the computer to charge the battery for
at least twenty minutes. If the  DC IN/Battery
indicator starts to glow after this period, allow the
battery to continue to charge for at least another
twenty minutes before turning on the computer.
However, if the indicator still does not glow, the
battery may be at the end of its operating life and
should be replaced. However, if you do not believe
the battery is at the end of its operating life, you
should speak to your reseller, dealer or service
provider.
Battery doesn’t
power the computer
as long as expectedIf you frequently recharge a partially charged
battery, the battery might not charge to its full
potential - in these instances you should fully
discharge the battery and then attempt to charge it
again.
Check the  Power saver  option under  Select a 
power plan  in the Power Options .
