Check that screen resolution and color quality are correctly set.
Check that the monitor type is correct. This information is
available under the menu Display Settings  Monitor.
Confirm that the display device driver is installed correctly. This
information is available under the menu Personalize  Display
Settings  Advanced Settings  Adapter. The Adapter Infor-
mation window should display the correct device driver name.
NOTE: The device driver name depends on the video chip that
has been installed on your computer. Click the Properties button
and check the "Device status" box to confirm that the device is
working properly. If not, click the Troubleshoot button.
Check that your application and operating system are correctly
installed.
Check that the surface of the screen is not scratched or dam-
aged. If there is no visible damage, these small idiosyncrasies
are a standard element of TFT screen technology and will not
affect the computer's performance.
Sound
Confirm that the Mute function is off.
Check that no external device, such as a headphone or speaker,
is plugged into the audio output (headphone) jack.
Check that speakers are selected as a playback device.
Battery
Remove and reinsert the battery. If the problem persists, you
may need to replace the battery.
