I think I have a problem with EFI
Hi everyone,
I have a MacBook Pro 13" (2010) with OS X Yosemite 10.10.3. OS works fine, but since few weeks I have the following problems:
- when the battery is low and my mac falls in stop mode automatically (and it copies all RAM contents into hard drive), I plug the AC in and turn mac on but instead of a gray screen and full session restoration (when mac should copy all contents back to the RAM), mac reboot and starts a new session;
- I tried a SMC reset but it doesn't work (I can't see any changing of the AC status LED, and audio volume also doesn't change);
- I tried a PRAM reset but it doesn't work (I hear just one bong sound, instead of two);
- I tried a brand new OS X installation but also Internet Recovery doesn't work.
Can you help me with this?
Thanks!
MacBook Pro, OS X Yosemite (10.10.3), 13", mid 2010, 2,4 GHz Core 2 Duo, 4 GB
