Sleep mode does not remain constant

Greetings all you Harmonica players!!! Hope you're all fined tuned for the Christmas season!!!

I've Windows Vista Home Premium that when set to sleep mode, works. Well, it works several times and then it doesn't.

I've got it set at High Performance - put computer to sleep = 25 minutes. The same setting is found in the Advanced settings - in Multimedia settings, I've presently got it set at "allow the computer to enter away mode" - I've tried the "prevent idling to sleep" and the "Allow the computer to sleep" --- all with the same results, that being, it will work several times and then it refuses to work after that.

Any idea as to what I might do to keep this thing going to sleep when it is supposed to?

hello

I just read this thread and some others. some people say it can be done others say it can't.

good luck

Thanks for the reply Kenny - the *some* that say it can't be done at this point are correct. If I could get this fixed, then the *some* that say it can be done will be correct. Read that thread - nothing in that that helps me out so far. Appreciate your effort mate!
