A few months ago I bought a used HP notebook which has been wonderful until now. But today something really unusual happened: I tried to lock the laptop as I usually do, only this time nothing happened. The screen just stayed there as if I hadn't commanded it to lock.
I tried putting it to sleep but to no avail. Then I tried hibernation and the screen did turn dark, but when woken up, the screen right away reappeared, unlocked.
Finally I decided to just shut it down and restart because that can take care of quite a few problems. Imagine my surprise when I realized that I can't even do that!
Now I can only think of two things, either unplug it and wait until the batterie is drained (not appealing at all but quicK) or do a system restore.
What makes me nervous is that this might perhaps be a virus?
