Turning on my Macbook Pro
My 3 year old Macbook Pro is making 3 beeps as I try to wake it up. Any ideas?
OS X Mavericks (10.9.2)
This
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
or
3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.
