Keyboard & Trackpad Dead

[thormarketing]

My computer got a bonk on its head and the keyboard/mouse are not responding.

External devices work (USB keyboard & mouse) and it seems to operate fine, but the built-in keyboard mouse are non responsive.

I tried resetting the PRAM but no response (seems keyboard is *really* dead). I tried restarting, still didn't work. I turned it off, now it wont turn back on (power button *really* dead).

I'm assuming its a hardware problem and not software? Anything else to try?

Maybe the touchpad/keyboard ribbon cable got disconnected. Try pushing it back in.

Check iFixit for details.

Thank you! Good advice.

I also learnt that liquid damage (even small amounts from cleaners and damp cloths) can get into the trackpad and its connecter that is located very close to the seam of the trackpad... But it reseating the cable doesn't work, you could always try to use a deoxidizing contact cleaner on the connecter, and replace the cable (you can find them for the price of a starbucks drink on eBay) and it should work again
