Q: MacBook won't start up
My MacBook (2010) no longer starts up. When I press the power button, it boots up but hangs at this screen before shutting itself down.
The day before, I had put it into standby and it had run out of battery while in standby. I've done this many times before and normally it resumes fine.
I can get into the recovery partition okay, but am wondering if anyone knows how to fix this as I really do not want to do a clean install :/
Any help would be greatly appreciated.
MacBook, OS X Yosemite (10.10.3)

Did you try the Disk Utility as found in OS X Utilities, via Recovery? With that you could
try & repair the hard drive; it may (or not) give you a warning if the drive is going bad...
Usually running out of power, repeatedly, is bad for the battery and then you have shortened
its life by so doing. You may have to consider having a diagnostic test performed to see if
there is a problem with the hard drive, the charging circuit, battery, and Magsafe adapter.
And the cycle count in system hardware profile for battery, may appear low, but after the
full-discharge events, it would never be able to have as long a prospective life as intended.
An Apple Store with Genius bar may be able to help test these &/or offer suggestions. And
if it requires service, that may be due to damaged files or bad sectors on the hard drive.
By frequent power interruptions, the software on the hard drive may have been corrupted
to the point of there being other issues including start-up failure; or circuit board damage.

Hopefully the matter isn't too involved to get it working again.
Good luck & happy computing!
