Chapter 6
If Something Goes 
Wron g
Some problems you may encounter when using your 
computer are relatively easy to identify and solve. Others 
may require help from your network administrator or the 
manufacturer of the software program.
This chapter aims to help you solve many problems by 
yourself. It covers the problems you are most likely to 
encounter.
If all else fails, contact Toshiba. You will find information on 
Toshiba’s support services at the end of this chapter. 
Problems that are easy to fix
Your program or application stops responding.
The operating system allows for the use of both 
applications (“Apps” used with the Windows® “Modern 
UI”) and programs (used in the traditional Windows® 
desktop environment). For the purpose of simplifying the 
information we will use the terms interchangeably in this 
chapter.
NOTE

Problems when you turn on the computer
If you are working in a program that suddenly freezes, 
chances are the program has stopped responding. You can 
exit the program without shutting down the operating system 
or closing other programs.
To close a program that has stopped responding:
1Press 
Ctrl, Alt, and Del simultaneously (once), and then 
click or touch 
Ta s k  M a n a g e r.
The Task Manager window appears.
2Select the program or application you want to close, and 
then click or touch 
End Task in the lower right corner.
Closing the failed program should allow you to continue 
working. If it does not, continue with the next step.
3Close the remaining programs one by one by selecting 
the program name, then select 
End Task.
Closing all programs should allow you to continue 
working. If it does not, power off your computer, and 
then restart it.
Problems when you turn on the computer
These problems may occur when you turn on the power.
The computer will not start.
Make sure you attached the AC adaptor and power 
cord/cable properly.
Press and hold the power button for at least 10 seconds.
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 Power 
button. If the button is glowing, the computer is on. If the 
button is not lit, try turning the computer off and then on 
again.
If you are using an AC adaptor, verify that the computer is 
receiving power from the external power source by checking 
the AC power light located on the left side of the computer. If 
the indicator is glowing, the computer is connected to a live 
external power source. 
						

							124If Something Goes Wrong
Problems when you turn on the computer
The computer displays the WARNING RESUME 
FAILURE/Windows Error Recovery – Windows did not shut down 
successfully
 message.
To continue, select 
Start Windows normally. This can 
happen if the computer was put into Sleep mode and the 
battery has discharged. If you performed a shutdown before 
this message was displayed, a program or driver may have 
prevented Windows
® from shutting down.
Data stored in the computer’s memory has been lost. Data 
stored in the computer’s internal storage drive may not be 
affected.
Always save your data even when you are using Sleep 
mode. If your battery fully discharges, information that has 
not been saved will be lost. Your computer can be 
configured to warn you when the battery is running low see 
“What to do when the main battery runs low” on page 85. 
If you are running on battery power, it is recommended that 
you do not leave the computer in Sleep mode for long 
periods of time.
To charge the battery, leave the computer plugged into a live 
wall outlet for several hours. For more information see 
“Charging the main battery” on page 81. 
The AC power light is blinking.
If the AC power light is blinking, try the following steps:
1Connect the AC adaptor to a different power outlet, 
preferably in a different room. If the computer starts 
normally, there may be a problem with the AC outlet 
itself, or the voltage level available from it.
2Verify that the AC adaptor is the correct unit for your 
computer model. The computer may not be able to start 
from an AC adaptor that is rated for less current 
(amperage) than the computer requires, even if the rated 
voltage is correct, and the plug fits correctly in the DC-IN 
socket. The labels on the bottom of the computer and 
the AC adaptor show the specifications for voltage (“V”) 
and current (“A”) for each device. The voltage level must 
match exactly. The amperage rating of the AC adaptor 
must be equal to or greater than that required by the 
computer.

The Windows® operating system is not working
3If your computer has a removable battery, connect the 
AC adaptor to the computer. Leave the battery out of the 
computer. Try turning the computer on again. 
If the computer starts normally, the battery may need 
charging, may be depleted, or may be defective. Turn 
the computer off, insert the battery, turn the computer 
on, and then leave the computer running for several 
hours, which will deliver a slow, steady “trickle-charge” 
to the battery. Once the battery has been trickle-
charged, it may begin working correctly again. 
If the trickle-charging does not prove effective, you can 
connect to Support Online by going to Toshiba support at 
support.toshiba.com.
The battery light is blinking when the computer is 
on.
If the battery light is blinking when the computer is on, this 
indicates a power mismatch. Do the following:
1Check the OUTPUT specifications on the AC adaptor 
(for example, DC 19V – 3.95A)
2Check the INPUT specifications on the bottom of the 
computer. 
The output specifications of the AC adaptor must match 
the input specifications of the computer. 
3If the specifications do 
not match, locate and use the 
AC adaptor that shipped with your computer. If the 
specifications 
do match, contact Toshiba. See 
“Contacting Toshiba” on page 150. 
The Windows® operating system is not 
working
Once you are familiar with your computer and used to the 
way the operating system responds to your work routine, 
you can easily detect if the operating system is not working 
correctly. For example:
❖The operating system fails to start after the initial startup 
appears.
❖The operating system takes a long time to start.
❖The operating system responds differently from the 
normal routine.
❖The screen does not look right. 
						

							126If Something Goes Wrong

Internet problems
My Internet connection is very slow.
Many factors contribute to the speed with which you can 
surf the Internet. They include: network speed, network 
conditions, time of day (when everyone else is surfing, your 
access can be slow) and popularity of the sites you are trying 
to access. If accessing a particular site is very slow, try later.
My browser cannot find the URL address I typed in.
Make sure you separated the domain names of the address 
with the forward slash (/). Check the spelling of each name 
and the syntax of the address carefully. A single incorrect 
letter or missed character will make it impossible for your 
browser to locate the site.
My browser cannot find a site I bookmarked.
The World Wide Web is constantly changing. A site you 
bookmarked yesterday may not be available today or its 
server may be down for temporary repair. Try again later.

Power and the batteries
The computer battery may not be accessible by the user.
Your computer receives its power through the AC adaptor 
and power cord/cable or from the system batteries. Power 
problems are interrelated. For example, a faulty AC adaptor 
or power cord/cable will neither power the computer nor 
recharge the batteries.
Here are some typical problems and how to solve them:
The AC power light does not come on when you 
plug in the AC adaptor and power cord/cable.
Make sure the AC adaptor and power cord/cable are firmly 
plugged into both the wall outlet and the computer.
If the AC power light still does not come on, check that the 
wall outlet is working properly by plugging in a lamp or other 
appliance.NOTE
