see my prior thread, "hibernate .... (a pain)"
had two machines, stopped hibernating, windows 7 machines.
extensive suggestions in prior thread, from this forum, for mechanisms to try to fix it. Unfortuantely, no solutions.
BUT, this week i retried hibernate, and it WORKED !!!
I had not done anyting different.
BUT, on retrospect, I HAD done something different.
I had first shut hibernate off
powercfg -h off
I hten restarted, then did a DEFRAGMENTATION.
even though windows does defrag'ing, this process when started manually took about 1 hour, had about 6 or 7 passes.
I then shut it down.
later restarted, worked with system, etc.
LATER in week, I retried hibernation on a whim, and it WORKED !! That was when I then posted to other thread that it had resolved on its own, not remembering that I had done the above steps.
SO, today, I decided to try this on my 2nd machine. (notebook HP machine). I first did a drive CLEANING (temp files, etc)
then did powercfg -h off
then did defragmentation.
powercfg -h onn
then tried hibernate.
it WORKED !!!
now, I don't know if my machines were a fluke, or if this actually can help to solve other's issues, but I'd like to knowk, by replies to this thread, if it helps others with hibernate issues, since microsoft can't give us any easy way to determine why hibernate suddenly stops working.
and, to all on this forum, thanks for your assistance also in the prior thread.
