Macbook won't start without power cord connected

[ClutchThese]

I'm currious to see if anyone here has ran into a problem with their macbook pro's turning on after you close the lid.

Every now and then the computer doesn't respond to anything. I open the lid, i close the lid... i reopen the lid, i press the power button... i hold the power button.

Nothing i do seems to get it to come out of hibernation. The ONLY way to wake it is to connect the power cord. (and yes, i know it has enough battery, i even hit the button on the side as it lights up all the green LED's).

So as you can imagine, being on a plane and wanting to do some work on your computer... only to be able to do nothing! The computer doesn't respond to anything to wake it. You HAVE to plug a power cord in, even if it's only for one second.

Good deal. I'll give it a go and see how it holds up.


I've realized it's called "Safe Sleep" It doesn't respond to anything until it senses an outside power source. Lame. 🙂

Isn't that what it does when you use your computer on battery till there's basically no power left so it goes into a low power state to save itself? /is confused.
