error causes it to fail. Choose this option only if 
Windows
® is stuck in a loop where it fails, attempts to 
restart, and fails again repeatedly.
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.

type of device, the drivers installed, and the system 
resources assigned to the device. 
To check a device’s properties:
1Swipe in from the right edge of the screen. When the 
Windows
® charms appear, touch the Search ( ) charm. 
Then touch the Search field, and begin typing 
Device 
Manager
.
2Touch 
Device Manager.
The Device Manager screen appears.
3In the list of device(s), touch the device type.
4To view the device(s) installed, touch the device.
The operating system displays the device Properties 
dialog box, which provides an array of tabs. They may 
include:
❖The 
General tab, which provides basic information 
about the device.
❖The 
Resources tab, which lists resources assigned 
to the device. This tab does not appear if the device 
is not using resources.
❖The 
Driver tab, which displays the drivers being 
used by the device. This tab also provides options 
for updating the driver or rolling back the driver in

The tabs that appear in the dialog box vary from one 
device to another. 
For more information about Device Manager, refer to 
Windows
® online Help.
Power and the batteries
The device’s battery is not accessible by the user.
Your device receives its power through the USB Power cable 
to the USB/AC adaptor or from the system batteries (one 
main battery and a real-time clock (RTC) battery). Power 
problems are interrelated. For example, a faulty USB Power 
cable or USB/AC adaptor will neither power the device nor 
recharge the batteries.NOTE 
						

							95If Something Goes Wrong
Display problems
Here are some typical problems and how to solve them:
The USB Power cable to the USB/AC adaptor work 
correctly, but the battery will not charge.
The tablet’s battery does not charge while the device is 
consuming full power. Try turning off the device.
The battery may be too hot or too cold to charge properly. If 
you think this is the probable cause, let the battery reach 
room temperature and try again.
If the battery has completely discharged, it will not begin 
charging immediately. Leave the USB/AC adaptor and power 
cord/cable connected, wait 20 minutes and see if the battery 
is charging.
The battery appears not to power the device for as 
long as it usually does.
If you frequently repeat shallow charge and discharge, the 
battery meter may become inaccurate. Let the battery 
discharge completely, then try charging it again.
Check the power options via your Power Plans (see “Power 
Plans” on page 70). Have you added a device that takes its 
power from the battery? Is your software using the internal 
storage drive more? Is the display power set to turn off 
automatically? Was the battery fully charged to begin with? 
All these conditions affect how long the charge lasts.
After a period of time, the battery will lose its ability to 
perform at maximum capacity and will need to be replaced. 
This is normal for all batteries. Visit the Toshiba Web site at 
accessories.toshiba.com. Refer to this site often to stay 
current on the most recent software and hardware options 
for your device, and for other product information.
For more information on maintaining battery power, see 
“Changing the battery” on page 72.
Display problems

Disk or storage drive problems
The display mode is set to Simultaneous and the 
external display device does not work.
Make sure the external monitor is capable of displaying at 
resolutions of 1280 x 800 or higher. Devices that do not 
support this resolution will only work in Internal/External 
mode, and not simultaneous mode.
Small bright dots appear on your TFT display when 
you turn on your device.
Small bright dots may appear on your screen display when 
you turn on your device. Your display contains an extremely 
large number of thin-film transistors (TFT) and is 
manufactured using high-precision technology. Any small 
bright dots that may appear on your display are an intrinsic 
characteristic of the TFT manufacturing technology. Over a 
period of time, and depending on the usage of the device, 
the brightness of the screen will deteriorate. This is also an 
intrinsic characteristic of the screen technology. When the 
device is operated on battery power, the screen will dim and 
you may not be able to increase the brightness of the screen 
while on battery power.
Disk or storage drive problems
Problems with the storage drive or with external media 
usually show up as an inability to access the drive or as 
sector errors. Sometimes a drive problem may cause one or 
more files to appear to have garbage in them.
Error-checking
Run Error-checking, which analyzes the directories and files 
on the storage drive and repairs any damage it finds. 
To run Error-checking:
1Swipe in from the right edge of the screen. When the 
Windows
® charms appear, touch the Search ( ) charm. 
Then touch the Search field, and begin typing 
computer.
2Touch 
This PC in the list that appears.

Sound system problems
Your data files are damaged or corrupted.
Refer to your software documentation for file recovery 
procedures. Many software packages automatically create 
backup files.
You may also be able to recover lost data using utility 
software. Consult your network administrator.
Some programs run correctly but others do not.
This is probably a configuration problem. If a program does 
not run properly, refer to its documentation and check that 
the hardware configuration meets its needs.
Sound system problems
No sound is coming from the device’s speakers.
Adjust the volume control.
Check that the volume control on the device is turned up.
If you are using external headphones or speakers, check that 
they are securely connected to your device.
The device emits a loud, high-pitched noise.
This is feedback between the microphone and the speakers. 
It occurs in any sound system when input from a microphone 
is fed to the speakers and the speaker volume is too loud. 
Adjust the volume control.
Printer problems
This section lists some of the most common printer 
problems.
The printer will not print.
Check that the printer is connected to a working power 
outlet, turned on and ready (on line).
Check that the printer has plenty of paper. Some printers will 
not start printing when there are just two or three sheets of 
paper left in the tray.
Make sure the printer cable is firmly attached to the device 
and the printer.
Run the printer’s self-test to check for any problem with the 
printer itself.
Make sure you installed the proper printer drivers as shown 
in the instructions that came with the printer.

Wireless networking problems
You may have connected the printer while the device is on. 
Disable Sleep mode, turn off the device, and turn off the 
printer. Turn the printer back on, make sure it is online, and 
then turn the device back on.
Try printing another file. For example, you could create and 
attempt to print a short test file using Notepad. If a Notepad 
file prints correctly, the problem may be in your original file.
If you cannot resolve the problem, contact the printer’s 
manufacturer.
The printer will not print what you see on the 
screen.
Many programs display information on the screen differently 
from the way they print it. See if your program has a print 
preview mode. This mode lets you see your work exactly as 
it will print. Contact the software manufacturer for more 
information.
Wireless networking problems
This section provides general troubleshooting tips for 
networking problems, specifically wireless (Wi-Fi®) 
networking.
The terms and concepts used assume a basic 
understanding of networks, and may be for more 
advanced users. If you need assistance or if you are not 
familiar with the terminology, please see Windows
® Help 
and Support or contact your computer technician.
❖If your device is equipped with an internal Wi-Fi
® 
adapter, verify that Airplane mode is OFF, see “Setting 
up for communications” on page 80.
❖Verify that your device can detect access points or 
routers. If it can detect a Wi-Fi
® access point or router 
then it may be a configuration issue.
❖Verify that signal strength is good using the utility 
provided with the Wi-Fi
® adapter.
❖If another device is on the same network, verify that it 
has network access, and can connect to the Internet. If, 
for example, the other device cannot browse to a public 
Web site, the ISP’s (Internet Service Provider) service 
may be disrupted.
