Chapter 5 Trouble Shooting
Display Problems
The display panel is blank when the system is turned on -
Make sure the computer is not in the Standby or Hibernate suspend modes. The display is turned off to
conserve energy in these modes.
The screen is difficult to read -
The display resolution should at least be set to at least 1280x800 for optimal viewing.
Go to [Start > Settings > Control Panel > Appearance and Themes] and double-click the Display icon.
Under the Settings page, set screen resolution to at least 1280x800 and choose at least 256 colors.
The screen flickers -
It is normal if the display flickers a few times when shutting down or powering up.
Keyboard and Mouse Problems
The built-in touch pad performs erratically -
Make sure there is no excess perspiration or humidity on your hand when using the touch pad. Keep the
surface of the touch pad clean and dry.
Do not rest your palm or wrist on the surface of the touch pad while typing or using the touch pad.
The built-in keyboard accepts no input -
If you are connecting an external keyboard to the system, the built-in keyboard may not work.
Try restarting the system.
The characters on the screen repeat while I type.
You may be holding the keys down too long while you’re typing.
Keep the keyboard clean. Dust and dirt under the keys could cause them to stick.
Configure the keyboard to wait longer before the auto repeat feature starts. To adjust this feature, Go to
[Start > Settings > Control Panel > Printers and Other Hardware], and double-click the Keyboard icon. A
dialogue box shows up with the adjustable settings for the keyboard.
