Problem
Solution
The screen is unreadable or
distorted.
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
Information 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.
Incorrect characters appear on
the screen.
Check that your application and operating system are cor-
rectly installed.
Missing, discolored, or bright
dots appear on the screen
every time you turn on your

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
No sound can be heard from
the speaker even when the
volume is turned up.
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.
