No Power on whatsoever, battery or magsafe.
I was using my Macbook as normal today, when it just instantly shut off. (Not like the battery had died and it would normally go into its hibernation).
I then tried to turn it back on, but it did nothing (no lights, fans etc..)
After looking at the magsafe I noticed that there was no status light on it whatsoever.
I tried my friends magsafe and it did the exactly the same thing. (As my current magsafe has a split in the insulation)
I then tested the battery voltage to see that I was getting around 11volts, and when the power button was pressed it did not dip or change at all...
When the laptop shut off it was charging, so I believe that there is sufficient charge in the battery to power on the laptop without a power adapter.
I have attempted to reset the SMC, however, because the MacBook isn't even powering on I doubt that I have successfully reset it.
I am very technically literate so I could do the repairs myself. Its just knowing what the problem is....
Is this a good question?
