I know this problem has been going on for a long time and still isn't resolved but I'm beginning to think that it is not a SP4 problem. Some thoughts...I have always had a problem with Sleep, on two desktops and a laptop. They never came out of Sleep properly
and I frequently had to do a hard shutdown (holding the power button down until the fans stopped, etc. When I started using Hibernate instead of Sleep, my problems stopped.
Of course, I never really saw the purpose of using Sleep on a desktop because my usage habits are such that the system is on when I'm around and Hibernate is fine when I'm away from the system for more than an hour or so.
Even with a laptop, I've always preferred Hibernate rather than the hassle of getting Sleep to work properly. On a side note - way back in 2003 with my first laptop - I had occasional problems with it getting very hot while in Sleep mode so I used Hibernate
instead.
All of this leads me to surmise that we are using tablets differently than we do our desktops and laptops and find that Sleep might save a little time. But, I've found that it only takes my SP4 about 17 seconds to come out of hibernation and back to exactly
were I was when I entered Hibernation and I'm no longer deviled by a problem with Sleep that has never worked properly for me before.
So, I would suggest that Microsoft try to fix the Sleep problem in general and that SP4 users relax during the approx.17 seconds it takes to come out of Hibernation and enjoy a really fine machine.
