Laptop crashes when entering sleep mode.

[l11]

Recently when entering sleep mode, the laptop does not go to sleep but crashes. When I go to restart the laptop, I get the windows as recovered from an unexpected shut down.

However I have noticed it does not crash, when I first turn the laptop on and at the choose user screen. Here it goes to sleep fine and resumes fine, any other situation and it crashes.

this has started over night, any ideas?

Thanks
