sorry joined this thread kinda late, but when i search for battery life for the 5670 all i can find about movies are "dvd playback" i can only assume that is when your putting the dvd into your dvd-rom drive. but what people dont tell you is if you run a ripped movie off your hdd. will it still suck the same amount of power out of your batteries? or will it reduce it? (if you run at full screen about 1/2 of the screen is black)
has anyone ever tried this? it might 'boost' battery time for all
Just because hlaf the screen is black doesn't mean the screen is using half the power. The backlight is a seperate unit from the screen, and whenever the screen is on, the entire screen is backlit. You cannot just turn off the backlight BTW, you wuldn't be able to see the screen anymore.
It would be best to play any movie off the HDD, the DVD generally uses more power, and if the HDD it spinning while the DVD is running, they are using almost twice the power.
However the whole thing is moot, because the CPU is doing a lot of work, and the CPU uses a LOT more power than the HDD or DVD.
