Vista Machine won't stay in standby

[Bascom King]

My wife's desktop machine is a HP a1730n running Vista Home Premium. After
putting it in standby state, after a short while, it comes back up into
operation. It does this most of the time but sometimes, it will stay in
standby all night. I asked the group about this before and got the advice
to to into advanced settings in Power Options and change the multimedia
setting "when showing multimedia" to "allow the computer to sleep". This
seemed to fix it for a while but it then reverted back to not staying in
standby. I am looking for some more advanced wisdom on this and hoping for
a solution that works!

Thanks in advance,
Bascom King

Does moving the mouse cause it to wake up? I've seen systems where the
mouse, without being touched, would move enough to wake it up. Try
turning the mouse upside down *before* putting the system to sleep, and
see if it stays that way.

From an elevated command prompt, run the command "powercfg -lastwake" without
the quotes, and see if it lists what woke up the computer.
