Sleep
When my computer goes into sleep mode I can not get it to wake.
How do I do this?
I have tried pressing different keys on the keyboard, this does not work (after pressing the windows key a high pitched noise came from the computer, this could only be stopped by switching the computer off at the rear).
I have also tried pressing the power button on the front of the pc, this does not work either.
