i recently built my machine. it was working fine doing things in windows and out. i have an SSD now and liked how smoothly the computer would resume from the default sleep mode power settings that came with win7, so for the first time i've actually been using them on my desktop.
however, since installing sp1, sleep no longer seems to work. when i woke up this morning and when i came home from work, the computer was not in sleep mode. normally i expect to see the power button flashing, and in neither case it was. when i start the computer it asks me how i want to enter windows, just like it does normally if windows crashes. everything else on my computer is working as expected.
