I left my HP elitebook 6930p idle for 5 hours, after which I noticed that I cannot open any applications. When I try to open an application via clicking an icon, my laptop won't respond (even notepad won't open). Note that the hard drive indicator drive is surprisingly inactive during that time. I can open windows explorer though, but it takes some time to load a page. The screen does not freeze (I can sitll move my cursor), but when I attempt to shut down it gets stuck on the wallpaper before fading [supposedly] to the loading screen. Please help!D:
