GlamGirl,
That's exactly what happened to my HP2133 Mini (twice now).
Each time it was a new motherboard replaced under warranty which I'm told is a fairly common occurrence on the HP2133.
The latest MotherBoard revision is supposed to have fixed the issue.
I've found another fix.
I went and bought an Apple macBook pro and don't use the HP any more thus ensuring it doesn't happen again.
Never looked back. The Apple is just brilliant ! (Thanks HP)
