If the speakers did not solve the problem, replace the logic board.
Mouse
My mouse doesn’t work at all.
Turn over the mouse and check the if the red LED on the underside of the mouse. Is the LED
lit?
Yes: The mouse has power. Try using the mouse on another surface. Non-reflective, opaque
surfaces without repetitive patterns work best. The surface should be clean, but not shiny.
Optical mice won’t work on glass, mirrored surfaces, glossy materials or mouse pads with
pictures.
No: There is no power to the mouse. Try plugging the mouse into one of the USB ports
on the machine. If the mouse won’t power on from any USB port, try it on a known good
machine. If the mouse fails to power on with known good machine, replace the mouse. If the
mouse will power on with a known good machine, replace the main logic board.
If the underside LED is lit and the surface is good, and the mouse still does not track, try
plugging the mouse into another USB port on the machine. Does the mouse track now?
Yes: Issue resolved. Try the other USB ports on the system to make sure you don’t have a bad
port.
No: Try using a known good mouse. If a known good mouse resolves the issue, replace the
mouse. If a known good mouse does not resolve the issue, replace the main logic board.
My mouse works intermittently (the cursor freezes randomly) or is slow to
respond.
Try using the mouse on another surface. Non-reflective, opaque surfaces without repetitive
patterns work best. The surface should be clean, but not shiny. Optical mice won’t work on
glass, mirrored surfaces, glossy materials or mouse pads with pictures. Does the mouse track
correctly on a proper surface?
Yes: Issue resolved.
No: Check the Mouse Tracking setting in the Mouse control panel.
Boot to another volume (like the System Install Disc). Does the mouse track properly now?
Yes: Reinstall System Software
No: Try a using a known good mouse. If a known good mouse resolves the issue, replace the
mouse. If the issue persists with a known good mouse, replace the main logic board.
