Hi, I have an MacBook Pro 13", Unibody Mid 2010, 2.4 GHz, dual core i5, Model# A1278. It seems to be normal when I started it up. But it kept turning off after I logged in. What’s problem can it be? So far, I tried to start up by holding Command key + R. Then it took me to the OS X Utility screen with 4 choices “Restore From Time Machine Backup”, “Reinstall OS X”, “Get Help Online”, and “Disk Utility”. What problem do I have? And is it possible I can backup my latest data to an external HD now? Thanks in advance for any help!
mmm … So you don’t have any display after you log in with your user account, but if you leave it at the login screen its OK for a good amount of time (good 1/2hr)? At this point I suspect you have a corruption on your drive, so the user account files are damaged. Do you have another user account on your system? Guest is available by default (unless you took it off). See if it works. It’s likely you’ll need to boot up under an external bootable drive (USB thumb drive or HD). Then run Disk Utility and run Repair Permissions a few times and then run Repair Disk. If that doesn’t do it you’ll need to try recovery from a TM backup which hopefully you have. Otherwise you’ll need to scratch the drive and re-install the OS and everything else - Ouch! As to backing now if you can get the external disk to boot up you might have a chance. If you enabled file encryption then the answer is no.
