I have a Sony Vaio VGN-FE11H and whenever it goes to the sleep mode and I try to turn it on again it just wont do so and the screen stays black ! You can do whatever but only holding the powerbutton for long enough works ! I have heard that there might be a relation to Windows Vista Ultimate I am using !
I am thankful for any help !
Did you have the same problem without Vista Ultimate?
However, I think this is driver problem and not because of Vista Ultimate.
--latest Vista drivers for your VAIO --
Before Vista never and now I do !
Have you tried the Video card update and the bios update on the page that seb has linked to above^^?
