I'm trying to reduce the heat my laptop gives off and save power. I have an Inspiron 600m with 1.6GHZ Dothan and 64mb ATI Radeon 9000 Mobility. I tried using ATI Tool and created a profile where i reduced the memory and core speeds. I found stable levels and it worked just fine while the laptop was plugged in. Having Powerplay still enabled, I unplugged the AC adapter and the screen started to go fuzzy like a TV with horrible reception. The screen would go back to normal if i plugged the AC adapter back in. Also, if I disable Powerplay, then everything is fine. So, to make it short, is there any way to make Powerplay and ATI Tool to work effectively in tandem? Thanks in advance.
