No use of Keyboard or Trackpad

2.2 GHz A1226 machine: I have recently lost the use of both my keyboard & trackpad simultaneously.

Keyboard Backlight, power button, light sensors, in fact everything else works just fine.

Any ideas ?


Hi folks, thanks for the fast answers,

An external keyboard & mouse both work fine on usb & blue tooth & yes it was a liquid spill !

In fact a pint of beer thrown at my mixing console during a live concert !

Luckily the £80,000 mixing console survived, but my mac took the most damage.

I already had the screen replaced under insurance as it instantly had vertical weird lines down it after it's little drink, but then my insurance ran out before the keyboard & track pad died a couple of months later. It has been however a year since that & nothing else has gone wrong.

So it looks like I need a new keyboard & top case ?

Does anyone know if there is a way to test before splashing out on the new parts (t case & keys) to eliminate the logic board ??

Many thanks in advance,

Before I replaced anything I would try an external keyboard and mouse to attempt to eliminate the logic board. Ralph

Well, you could try replacing the upper case (which includes the trackpad)

As for the keyboard, you should replace that too.

I was just about to add this question.

Mine was a liquid spill also.

The external wireless keyboard and mouse works great for mine also.

I was just trying to see how much it cost for the real keyboard and mouse anyhow because that is the only thing making my computer look bad because some keys are broken off also.

Yes its best and less expensive to get the wireless ones.

Thanks for sharing your problems and solutions.
