My left shift, control and option keys stopped working
Hey, really hoping one of you could help me with my problem..
I have a 15" Mid 2009 MacBook Pro. The laptop suffered from a spillage and the result was the left shift key was always on. So I ordered a new keyboard/backlight and fitted it to the top case. Last night after putting it all back together it booted on and I swear the left shift key worked as did everything else.
This morning when I turned it on I noticed that the left shift, left control and left option keys are all unresponsive (checked with the onscreen keyboard).
I have tried the following:
- re-installing Lion from scratch.
- resetting the PRAM with right option, control, P + R. (rebooted 3 times to make sure)
- resetting the SMC - as I cannot do this with the keys, I removed the battery and held down the power button for 5 seconds. The clock reset so I assume this worked?
- re-seating the keyboard ribbon cable.
Does anyone have any ideas or solutions?
Does anyone know if one of the connectors on the ribbon cable signify these three buttons? (i.e. are the buttons grouped together on one pin which I could attempt to clean etc)
Any help, info or suggestions would be VERY much appreciated!!
