This is really strange. I tried to watch an HD movie just now, but it kept lagging, and just would not work. The audio played, but the picture was frozen. But when I pull the power cord, it plays perfectly. The moment I put the power cord back in, it starts to lag again. Unfortunately my battery sucks, so I can't watch a movie without the power cord.
Anyone else experienced something similar? Know of a solution?
Odd, I actually get a touch faster internet with the power cord attached.
It could be something to do with your Power profiles. In Windows at least you can set different settings for when you're plugged in and unplugged. A co-worker of mine was experiencing this problem and checked. He had it in Power Saver mode when it was plugged in and High Performance mode when it was unplugged.

I have xp, so no power saver or high performance mode.
XP still has power settings available in the Control Panel. You may want to take a look.
It seems like cpu usage drops when I pull out the power, like something is using the processor only when the power cord is in. The CPU usage is somewhere between 48% and 65% when the power is connected. When I pull it, It drops to 15% to 29%. And it is Firefox and Azureus who take up most processing power. When the power is connected, they account for 35%. When I pull the power, they use less than 10%.
I checked the power settings jason, but there is only controls for when the computer should turn off the screen, hard drive, etc. Nothing on CPU throttling.
Edit:
Ok, so if you write powercfg in the command line, you get lots of options, among them a way to throttle the cpu. I set the throttling to be the same on DC and AC, but it still lags on AC power.
a constant 15-29% is insanely high. if you just leave it what does to hover around? right now my desktop which is running Aim, Steam, and Ie is using between 0 and 4% of the cpu.
something to keep in mind, most laptops have a power save feature which will turn the cpu down to conserve power. so its likely that whatever program you have running on your computer taking up 48-65% of the cpu is being knocked back a bit by the fact that the computer is going into a power save type more.
