I hve had this recurring problem with my pc. I have it set to go into hibernation when the key is turned. It enters and resumes from hibernation flawlessly, most of the time.
However, if I leave the car off for a long stretch (over night, or a full day at work) when i turn the key, it resumes from hibernation, and them promptly restarts the machine. This only occurs if it is left for a significant amount of time. If i left it for only a few hours, it resumes with no complications.
I did see any thread that described this sittuation. Any insight as to why this might happen?
