Computer no longer enters standby on it's own

solved it by disabling services. Attached is my list of safely disabled services - PC still boots so I must be doing something right!!!

My theory is that a recent Microsoft Update broke something in the standby process, at least for XP. I have two XP systems here that don't go to standby on their own any more. They were working fine, then a couple of months ago or so they both just started staying on.

My sons Vista system and my wifes Win7 laptop both go into standby and hibernate just fine.

try removing java that always does it for me
if that fixes change the way java does it updates when you install it again

I had the same problem. I found that for some reason I was getting network requests for service.
I found that by entering 'Powercfg -requests' in a 'CMD.EXE' window there were outstanding requests, from various sources(Must run Cmd.exe as an administrator).
The only quick way I found to clear them was to reboot the system, after which the system would hibernate correctly.

I have since fixed my problem by writing a VB.Net program to hibernate the system at the end of a recording if all of the condition are correct.
Unfortunately I am not able to make it generally available due to licensing restrictions. If I could access the GBPVR.db3 database, from VB.net express, without using an external program then it could be made available.

I don't think this applies to XP though - -requests came in later versions AFAIK
