My almost 4 year old HP laptop for the past 4-6 weeks has been ramdomly hibernating - pretty regularly.
I can be working for 10 minutes after waking it in the morning and it will hibernate with just a quick warning. It will sometimes come back immediately on its own or require me to press my power button. It might then do the same (hibernate cycle) 2-10 times before it either stays on for hours or it shuts down completely - losing any unsaved data. Then I restart it and it can work for hours or start all over again.
I am running low on HD space, there is a Hibernate tab under the Power Settings Control Panel that indicates that I need over a gig for hibernate and I have under a gig available. Is that the problem? Some postings mention the possibility of a recent XP update causing the problem?
I did notice what seems like the fan running more often so perhaps a CPU or mobo issue, but at times the hibernating problem occurs when the fan is dormant.
I am planning on getting the new Macbook rumored for October 15th-ish and running XP and Vista on it via virtual machines.
But in the meantime any and all ideas and advice is appreciated, this is driving me c-R-a-Z-y!!!
