ok at my school they issued everyone a laptop with adobe premier and other good stuff, and i need know a way to make my power run for 6 hours, i only need to have the internet and the harddrive running because im uploading clips, so i was wondering if there was a way to make the life of the battery to 6hours, at 95 precent it can last about 4horus n 30 mins i have a sony vaio with an extended power pack, i want something to run similiar to stand by. I want it so that only things active r running but does anyone know a setting i can use??

Once upon a time, there was this man named Westinghouse, and he invented this really cool thing called AC power, or alternating-current power. Unlike DC, or direct-current, power, it did not exhibit high attenuation over long distances.

This amazing invention is something that you don't have to wait to use! You, too, can join in the fun by PLUGGING YOUR LAPTOP'S AC ADAPTER INTO A SOCKET!

In all seriousness, if you're attempting to run for 6 hours with that kind of activity, you're going to need an external power pack or a really high-capacity battery. You can optimize some things but there's only so far software can go.

The primary sources of power drain are

(1) laptop monitor, specifically LCD backlight. BIGGEST POWER SUCKER EVER. Turn down the brightness and you'll get at least another half-hour of battery life.
(2) hard drive. Spin this down when you're not using it.
(3) wireless LAN devices. Turn it off when you're not using it.
(4) CPU and other components actually don't draw that much in comparison, and you can clock them down. I have mine set go to ~70% of its full speed when on battery.

Here's another thing you can do. If you change the power settings, you can close the top of the laptop and have the LCD turn off and the rest of the machine stay on. Saves alot on batteries.

sometimes i download shit, and it takes over 6 hours cuz there huge files ranging from 1 gb - 7 gbs and due to the wireless connection it randomely bounces the kbs around and the severs suck so i only get 6 - 500 kbs
