    Is anybody experiencing the same issue of around -2000 mA power draw on ML according to the system utilities? It now lasts 3:30 on battery instead of the 7:00 it used to get. I don't even know why it started because it just randomly started doing this. I don't know why my computer is using up that much power. My cpu shows about 95% or more idle. Is this a problem with a file being corrupt or what?

    It doesn't get to 95% unless it's doing something. So find out what something, and maybe u can tell it to, only do that when on AC power.

    No i mean the cpu is at least 95% idle most of the time. There's only about 5% cpu usage shared between User, System, and Nice according to my system stats toolbar thing.

    Used to get 7 =/. Check the power draw using the system information power tab (apple -> system information -> power). if i can recall a regular running macbook pro draws about 1000 when on near full brightness and web browsing. Also check your activity monitor for cpu hogging apps.

    Something has got to be running in the background. (Probably the Flash player plugin that runs within the browser... or Java... or something else... including animated GIFs...)

    How many browser windows do you have open at any given time?

    Have you ran your MBP with no apps running?

    Or with Activity Monitor running?

    2:50 seems very low, just for web browsing...

    Good call. I have youtube in one of my inactive tabs thats probably why. Will check if my battery life goes up. Wouldn't the flash plugin use up cpu though so it should show up in the activity monitor?
