t61p 6459CTO monitor wont turn off

[Hakubi]

Hello,

Been having a problem with my thinkpad T61p (bios dated 6/6/2008)

I'm using windows XP pro 32bit, fully up to date and have killed all non essential programs from taskman that i can think of and my computer STILL wont turn off its LCD monitor (via energy star count down or FN-F3 shortcut)

it shuts off fine for a couple minuets but then randomly wakes up as if i have touched the mouse or a key...I'm thinking it has to be either a service or an application im overlooking but have no idea where to start...i will provide logs upond request.

Can anyone help?

check whether you have wake on lan activated in BIOS>

everything i could see in bios relating to waking has been disabled from the start.

Ubuntu 8.10 has no problems keeping the monitor off until i move the mouse or hit a key, its just windows XP ... is there a way to see what handle or program is interupting the sleep mode on my LCD?
