And, you could check the fuses with a multimeter but DON'T.  Not unless you have already desoldered them from the motherboard.

Why not? I've never had a problem testing them with a VMM/DMM.

For the original poster: the fuses on the A3000s are like resistors, but green and without stripes. I forget about the A4000... But first test with a working mouse, if you have one, that will point to the problem source: computer or mouse.

If the fuse is open, you are not measuring the fuse anymore, you're measuring some part of the motherboard.  This may give a false reading.

OK, thanks for explaining AMC258, but assuming you've set your meter to connectivity mode, if the fuse is blown, it'll immediately have > 0Ohm reading, and thus not beep, thus giving you the same results (in other words you'll get a beep only when the fuse is not blown, which is enough to help decide if it's blown or not). Right? OK, if the circuit is shorted elsewhere, it'll still beep, even though the fuse is blown. You'd have to be extermely unlucky though, you have to admit :-)

Also, then you are forcing whatever current from your multimeter through some part of the motherboard, which in most cases you can get away with, but it's bad practice.

OK, agreed, but I'm lazy when it comes to fuses :-)
