I am having a similar problem with 9.10 (clean install) on Dell 700m laptop. Power management worked great with 8.10 but with 9.10 whenever I plug or unplug the laptop power adapter, the machine goes into sleep or hibernate (whichever I have set in the power options). This happens regardless of the state of charge of the battery and it happens on both plugging and unplugging the power adapter. The first message in dmesg after the unplug is: [ 287.600663] b44: eth0: powering down PHY This seems to be initiating the sleep or hibernate action. I had 8.10 installed on this machine before and never had a problem like this. Power management worked perfectly with sleep and hibernate and I could plug and unplug the power adapter without causing a sleep or hibernate event.
