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.
The AC adapter and power cable work correctly, but the 
battery will not charge.
The battery doesn’t charge while the computer is consuming 
full power. Try turning off the computer.
The main battery may not be inserted correctly in the 
computer. Turn off the computer, remove and replace the 
battery.
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 AC adapter and power cable 
connected, wait 20 minutes and see if the battery is charging.
If the battery light is glowing after 20 minutes, let the 
computer continue charging the battery for at least another 20 
minutes before you turn on the computer.
If the battery light does not glow after 20 minutes, the battery 
may have reached the end of its useful life. Try replacing it.
The battery appears not to power the computer for as 
long as it usually does.
If you frequently recharge a partially charged battery, it may 
not charge fully. Let the battery discharge completely, then 
try charging it again.
Check the power options using the Toshiba Power 
Management Utility. Have you added a device, such as a PC 
Card or memory module, that takes its power from the 
battery? Is your software using the hard disk 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.

Keyboard problems
If, when you type, strange things happen or nothing happens, 
the problem may be related to the keyboard itself.
The keyboard produces unexpected characters.
A keypad overlay may be on. If the numeric keypad or cursor 
control light is on, press Fn and F10 simultaneously to turn 
off the cursor control light or press Fn and F11 
simultaneously to turn off the numeric keypad light.
If the problem occurs when both the keypad overlays are off, 
make sure the software you are using is not remapping the 
keyboard. Refer to the software’s documentation and check 
that the program does not assign different meanings to any of 
the keys.
You have connected an external keyboard and the 
operating system displays one or more keyboard error 
messages.
If you have a second keyboard, try it. If it works, the first 
keyboard may be defective or incompatible with your 
computer.

Disk drive problems 
Problems with the hard disk usually show up as an inability to 
access the disk or as sector errors. Sometimes a disk problem 
may cause one or more files to appear to have garbage in 
them. Typical disk problems are:
You are having trouble accessing a disk, or one or more 
files appear to be missing.
Make sure you are identifying the drive by its correct name 
(for example, C:).
Error-checking
Run Error-checking, which analyzes the directories, files and 
NT file system (NTFS) on the disk and repairs any damage it 
finds:

software, which is available from your dealer.
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.

The color of the materials used to make the disc can affect its 
reliability. Silver-colored CD-ROMs are the most reliable, 
followed by gold-colored CD-ROM. Green-colored CD-
ROMs are the least reliable.
WinDVD problems: General issues
WinDVDTM has been configured to provide optimum 
performance and quality based upon your system’s available 
resources. Changes made to the system or its configuration 
may impact the playback performance of the WinDVD 
player.
WinDVD controls are disabled.
Controls may be grayed out by commands on the DVD. For 
example, it is common for DVD movie titles to disable fast-
forward and rewind during the legal notices at the beginning 
of a movie.
Playback performance is poor.
The use of DMA dramatically increases the DVD playback 
performance of your system.
To make sure DMA is turned on and to check its settings:
1Click Start, then Control Panel.
2Click the Performance and Maintenance icon, then 
click the System icon.
3Click Hardware tab, then the Device Manager button.
4Double-click IDE ATA/ATAPI controllers to expand it, 
then double-click Secondary IDE Channel.
The Properties Box appears. 
5Select the Advanced Settings tab, then select DMA if 
available from the Transfer Modes drop-down list. In 
the correct device area, click OK.
6The system must be restarted for this setting to take 
effect.

The Root or Title menu does not open.
Most DVD titles have one or both of the “Root” and “Title” 
menus. If one menu button appears to do nothing, try the 
other menu button.
WinDVD performance decreases after making a system 
change.
DVD playback performance is dependent upon several 
system resources. Changes to these system resources caused, 
for example, by installing a new graphics or audio card may 
impact performance. Some software changes may also 
impact playback performance (for example, downloading 
new drivers from the Web). 
Before installing a new hardware or software component on 
your system, check for any potential conflicts between its 
resource requirements and your current system configuration. 
Also, if you change your operating system, check with your 
PC manufacturer or your graphics card vendor to ensure that 
you have the appropriate drivers for both your hardware (for 
example, the graphics card) and software (drivers must 
support the operating system and DVD with WinDVD).
Slow playback performance.
DVD playback is a resource intensive application. Other 
applications and/or changes to your system hardware, 
software or configuration can impact playback performance. 
If playback is slower than normal, try:
1Closing any other open applications to improve the 
performance of the DVD playback. 
2Ensuring DMA is turned on. (See “Playback performance 
is poor.” on page 197.)
3If you have installed new hardware (such as a new 
graphics card or audio card), ensure the component’s 
drivers support Microsoft
® DirectX® 5.2b or higher and 
WinDVD. Contact the manufacturer of the component.

4Verifying that your display driver resolution, color depth 
and refresh rate are optimal for DVD playback. (Some 
systems do not support video overlays if these parameters 
are not optimal.) Try lowering these settings to improve 
performance.
WinDVD problems: Content issues
Movies exhibit poor performance of “Directors 
Commentary” or other similar optional content 
versions.
Some movies may exhibit poor performance of these 
features. In particular, the video portion of the movie may 
become jerky or show pauses. The normal version of the 
movie will not show this problem.
WinDVD will not function properly with “debug” 
software installed.
The WinDVD application will not function properly if it 
detects that debug software is present on the system. Remove 
the debug software to restore functionality of WinDVD.
Minimum system requirements
WinDVD performs best when these recommended 
components are present in your system:
❖Sound card (with 48 KHz sampling rate support) 
❖DirectX® Foundation 6.0 or higher (Source: Microsoft) 
❖DirectShow® 6.0 (Source: Microsoft) 
❖DVD-ROM drive with DMA enabled (only available 
with Microsoft OSR 2.1 or above with PIXX 4.0 and 
USB support added) 
❖WinDVD software
