I'm not sure why, but recently my computer started not coming out of sleep properly. Now, when it comes out of sleep, I get the background graphic, and the pointer moves, but none of the windows icons or the taskbar comes up. There is some periodic HD activity, but when I pull up taskmanager, not much is going on in terms of processor activity. 99% or so system idle function.
Really, really frustrating.
FWIW, I've searched here and have seen that others have a wake up issue with the screen not starting...
Could you provide more details regarding your system? Operating system used, service packs installed (if any), whether this is a clean install or factory default installation of the OS... There's just not enough information to go on to offer a potential resolution to the issue.
