It would *probably* disappear from device manager but not positive.
Hard power cycle the computer. Remove charger and battery and wait 1 minute.
Plug in both and turn it on. Try to get into bios (usually either F2 or Ctrl+Alt+Esc on Acer)
I agree that loose ribbon cable is most likely bet.
Often keyboards are fairly easy to replace/reseat. Typically it involves removing the bezel from the area between the keyboard & screen and unscrewing a few screws to remove keyboard. Ribbon is usually underneath keyboard. You can find a service manual for your laptop online to find specific instructions.
Replacement keyboards are typically <$40 on ebay
