What does one slow blink when pressing the power button mean?
I have a MBP 1278 that was, until recently, working fine.
One day I left it unattended for a bit, and when I returned it was on, but beeping, and the fan seem to be going at full speed. It was very hot, IIRC. I shut it down, and it has never turned on again.
The battery is fully charged. The only sign of life I get from it is, when I open the lid and press the power button, the sleep indicator light turns on, slowly, and then turns off slowly.
I tried the key combination to reset the SMC, I’ve unplugged the battery and pressed the power button for a few seconds, etc. Nothing has made a difference. I can’t even find an authoritative source of what light-blinking-once-slowly means.
Any suggestions?
