Trackpad, Keyboard, Wifi All Not Working

Hi,

I've just restored a macbook pro (mid-2009) that has been gathering dust. After re-installing Lion the keyboard, trackpad and wifi stopped working. They were working right before the update.

Any thoughts on what I can do?

I have so far tried:

resetting PRAM

Reset SMC

Starting in Safe Mode

None of these has helped.

I then upgraded to Yosemite and that hasn't worked either.

Possibly a hardware issue - especially given the age - but the fact that this all happened during a re-install makes me doubt that.

Anyone else have any suggestions?

Thanks,

Matt
