Windows 7: Another S3 sleep issue - Waking Immediately

Another S3 sleep issue - Waking Immediately

Ok I知 at a loss here.

I知 having a problem with S3 sleep, but after extensive searching my issue appear a little different than others.

After a fresh restart or power up, the PC can enter and resume from s3 sleep perfectly on command or by setting the system to sleep by istelf.

When woken by my USB remote it has no problems, once again entering sleep via command or by the system timer.
The problem I知 having arises if a wake timer has woken the PC up. If a scheduled TV recording or a task I create (even just opening up a text file) the pc will not be able to enter sleep again unless the PC is rebooted.

After this scenario of a wake timer to wake the PC and when the system is at idle (i.e. the recording has finished) the PC tries to enter sleep, but it is immediately woken back up. I can稚 manually put the PC to sleep either. The screen goes black, hard drive light goes out and sounds like all fans have stopped but only for a split second then wakes back up. The screen will then stay black until using the remote to wake up the screen.

What I have tried:
Bios set to S3
All drivers are up to date
Multimedia power settings to 殿llow the computer to sleep
Powercfg 紡 shows S1 and S3
Powercfg lastwake results
wake history count - 1
wake history [0]
Wake source count 0
Only USB remote has ability to wake in the device manager. (However I have also tried a mouse, then keyboard, all separately).
Network adapter set to not allow wake
Wake-on-lan, magic packet or pattern all to disabled.
Only windows programs loading on startup via msconfig
I believe I have checked all Scheduled tasks to ensure nothing set to wake up PC
MST tool
Wake timer is set to enable in power as this is a media centre PC

What is confusing me the most is that sleep will work perfectly until a wake timer has woken the PC.

Any help would be appreciated.

Mark.
