Option Key (ALT) always pressed even at startup with keyb unplugged!
I have a strange issue:
My Macbook Pro seems to have the OPTION key always pressed, even at startup, il boots with the partition selection screen every time, in Mac OS when I type something, strange symbol appairs instead of normal characters...
I have replaced the keyboard but same problem…
I tryed to disable OPT in the sticky keys options with no luck… so I tryed to unplug the keyboard flat cable inside the macbook and boot with an usb keyboard and it boots into partition selection screen like the OPT key is pressed.
Could be a motherboard problem?
Please help!
Ist dies eine gute Frage?
Probably get better advice from the more knowledgable Apple technical participants here but you may want to try cleaning the flat cable connectors with 90% or higher isopropyl alcohol to try and rule out any "bridging" effects, caused by contamination etc, between the connector's electrical contacts.
Edit: Realized rereading my comment above might be a big ambiguous; I was referring to the keyboard connector at the main circuit board side of things and not to the flat cable itself.
