Re: Dimension 2400 Keyboard Failure
My mouse is USB but I tried plugging the keyboard PS2 into the green port and it didn't work, and I got message "Error 8602 Auxiliary Device Failure" along with the usual "Keybord Controller Failure" and "Diskette Drive O Seek Failure" and diagnostic light D turning amber. After removing it and rebooting all diagnostic lights are green again. Next I plugged an optical mouse into the green port so I could tell whether it was getting power, and the red light on the mouse lit up briefly but then went off.
In case it means anything, the numbers lock light on the keyboard will still light when I hit the numbers lock key and will now go off and on when I depress and release the key, but nothing else indicates any "life" in it.
