Recent problem going to sleep
My laptop has a light on the back of the lid showing when it's on. Normally when I close the lid it goes to sleep & the light goes off. The past week I've noticed that the light is staying on-and when I open the lid it appears the computer has not gone to sleep as it should. Usually when I re-close the lid it does go to sleep. I might think this is just a task taking extra time to shut down but I've waited up to an hour & the computer still won't sleep until I open & close the lid (and not always then, particularly if I do it right away).
I don't see exceptional CPU usage but something's going on & I'd like to know what. I'm trying to eliminate unneeded processes that run in background, even when they don't appear to be active (i.e. using the CPU). The one I'm stuck on now is wmpnetwk. Supposedly this is used for media sharing-except that I have media sharing turned off & it still runs. Is there anything else that requires this? Is it safe if I just disable it via services?
I'm also trying to check taskhost. I've noticed that it hangs up, at least for a while, when I shut down. I've downloaded Process Explorer but can't seem to find out what's using taskhost. (As with wmpnetwk taskhost doesn't appear to be using CPU.) Nor is it always running when I check. (I need to be more systematic about checking when I notice the problem but often I'm in a hurry-I shut the lid as I'm heading out the door.)
Any other suggestions? Thanks.
