1 Disconnect and reconnect the mouse securely to the USB 

keyboard.

contaminants. Clean mouse if necessary. 

  The mouse 

contains a ball and several rollers that must remain clean. If 

either the ball or rollers are dirty, the mouse might not 

track properly. Refer to Tech Info Library article 6491: 

“How To Clean A Mouse.”

the USB ports on the I/O panel instead. If the mouse works, 

replace keyboard. 

4 If the cursor doesn’t move, replace the USB mouse.

5 If the mouse is connected to one of the USB ports on the I/O 

panel, switch to the other USB port. 

6 If the cursor moves, replace logic board.
