How can I restore the firmware on the MacBook Pro 5,1
I recently installed the latest firmware from Apple Software update. After the updates, the only way to power the computer on is to hold the power button while plugging in the AC adapter. It boots and runs fine but the fans run at high speed and it won't sleep by closing the display, keyboard backlighting no longer works nor does the sleep indicator light or even ambient light detection.
Apple doesn't seem to have a firmware restoration cd for this version (MacBookpro5,1). Do you have one or know where I might obtain an image to restore the firmware to factory condition?
