Q: Macbook pro shut down on its own and will not start again. Progress bar stops halfway.
Hello anybody that can help. My macbook pro seemed to shut down on its own when i placed my mobile phone on it but it will not start up again. I have tried everything but it stays on the the grey logo screen with the progress bar half way. My final attempt at resolving the problem was reinstalling os x. It hasnot changed a thing. I really dont wanna loose the info on it, cause I have not backed up in a long while. Can anyone help?

Which exact model is your MacBook Pro? Which version of OS X is it running?
The ability to only boot to a gray screen can be caused by a number of problems; however, none of them would be due to just placing your mobile phone near the laptop.
Some of the causes are:
- A hardware failure.
- The startup drive is not recognized.
- Essential OS X startup software is either missing or corrupt.
- A firmware update is required.
I suggest that you try starting up your MBP in Safe Mode. (Note: Before doing so, temporarily remove any peripherals connected to your MBP.) To do so, reboot or power-on the MBP, and then, hold down the Shift key immediately after you hear the startup chime. Keep holding it down until you come to the Apple logo screen. Eventually the Login window should appear. You will know that you are in Safe Mode as it will be displayed below the words "Mac OS X."
If you can boot up in safe mode, most likely, an issue with a third-party driver. Please post back your results.
