Solution
If the pointer doesn't move on the screen when you move the mouse, clean the
mouse. For an optical mouse, wipe the light sensor lens on the bottom of the mouse
with a lint-free cloth. For a roller ball mouse:
1 Remove the mouse ball by unscrewing the bottom of the mouse.
2 Clean the mouse ball with a damp cloth (not paper).
3 Use your finger to move the rollers in the mouse ball housing and remove lint
and dust.
4 Replace the mouse ball and screw on the cover.
The computer might have stopped. Reset the computer by pressing and holding
the computer On button until the computer turns off (approximately 5 seconds).
Then turn the computer back on.
Check that the TV is connected to the PC; see "Connecting the TV" on page 13.
Check that the TV out image is enabled; see "Enabling TV Out Image" on page 24.
Change the USB power support under Global Preferences on the Buttons tab of the
Control Panel Keyboard settings.
You cannot remove a CD or DVD after you have turned off the computer. Turn on the
computer and press the Eject button to extend the tray.
