ATI Powerplay not working ...

[sugo]

I am typing this message with t42 on battery. I have the latest IBM ATI driver dated 7/6/04 installed. It's a 9600 chipset.

No matter what I do, the advanced display info says Powerplay is inactive and it's running in high performance mode.

I did a fresh windows install. Would that matter? Power scheme is max battery.

Problem resolved. The ATI Hotkey Poller apparently is also responsible for switching Powerplay on and off.

Did you mean that disabling the ATI hotkey poller would fix the problem [ati2evxx]? Unfortunately, I couldn't get this fix to work as well on my T43p.

Enbaling Ati hotkey poller would fix this problem. I encouter the same problem a few days ago. Start>>Setting>>Control Panel>>Managing tools>>Sevices

When I was reading this thread, I went to the Powerplay tab to try some things, and I found out that I could not enter Battery Saving Mode when I had Powerplay enabled. I checked the ATI Hotkey Poller service and it was set to Automatic and Started.

I know I'd seen Powerplay work OK in the past so I was stumped for a bit. I finally found out the problem was that the TV display (S-Video) was active, even though I had the TV turned off (the S-Video cable was connected to the TV though). When I turned off the TV display in the Display tab of Display Properties, then Powerplay began working properly.
