Wenn my Macbook Pro goes to hibernation because of low battery and I try to wake it up there comes the progress-bar goes up untill the last stripe - then the boot process stops. iDevices light up and down at this point. Usually this is where the login screen would come. I hit the power button and force a new boot.
I'm experiencing this issue since I had upgraded to 10.8. from 10.6.
Here are the steps I've already tried - I'm just asking if I missed something in the list, that I also could try. I already spent so many hours whith this, I'm already accepting this planned obsolescence of my macbook pro. :-( A total nightmare - I should have never been made to upgrade (Xcode doesn't install in the new version.)
- Fixed Disk permissions. (A lot of times - with OS X started and in Single User Mode.)
- Repaired my volume. (The hard-off described above usually causes errors in the file system)
- Parameter Reset
- SMC Reset (can't confirm, that this actually happened, because there are no confirmations about this.)
- Change the hibernation modes in Terminal
- Remove startup items in System Preferences>Users
- Remove the sleepimage in /var/vm
- Create a new Admin-User
- Change my screensaver
- Delete my Power Managment Plist
- Delete the Systemuiserver Plist
- Clearing the caches with Onyx
I now change my hibernatemode to 0 and forget about owning a laptop and just leave it on my desk.
I would really appreciate any suggestions in pinpointing that down. And yes, I know there are already threads covering that problem resulting in the action-list above. I feeling kept busy with R&D that hasn't been made by apple.
So the last thing I will try someday is a fresh installation. But this will also take up so much time, that I just accept my buggy machine...
