But, Mayaman, it doesn't get 5 hours at that speed -- at least not according to my SpeedswitchXP. I had been using my 3790 at the local Starbucks this afternoon and decided to change my BIOS settings to accomodate maximum performance settings. This locked my CPU speed at 2ghz and adjusted my battery life meter from approx. 3.5 remaining hours to a little over 2 remaining hours.
Don't get me wrong, surfing the web and word processing for one hour and then playing Doom3 for an additional 2 hours is nothing to scoff at. But, with the CPU set at full speed all the time, the 5 hour battery life mark is unattainable.
My main question is: does having the CPU set at maximum capacity all the time but undo stress on the circuitry? Will it diminish the life of my Intel 755? If there is no harm done by having BIOS set at max, hey, that's great. But, I need this laptop to last me a few years and I don't want to mess things up by changing the CPU settings from the default max battery to maximum performance.
