Hi guys! I'm new to this forum.. OK, I just recently installed Service Pack 1 update for my Windows 7 Ultimate 64 bit and the problem that constantly bugging me is the hibernate mode. When I put my computer(I'm using a laptop w/c is an Acer 4730z) to hibernate mode and when I get back into it to wake it up it, it turns on but my computer displays just a blank screen and Windows will not be loaded..this happens every time when I put off my computer using hibernate mode..I cannot use sleep mode either because my computer also had a problem with it.. I already tried the hotfix provided by Windows w/c is KB2541014 and installed it and nothings changed, the problem is still persistent.. Since I'm using my computer everyday, which shutdown is not a good option for me and I'm relying with hibernate mode heavily.....so this is really a problem for me and I cannot figure it out myself... So I hope you guys can help me... Thanks a lot!!!!
