Acer provides a software package that is provided with all their laptops called "Empowering Technology" it also has a power management program which allows you to change the brightness of your screen, to even how fast your machine will run at. For a laptop to last longer you will have to slow it down to this program does it for you. To make your computer run at its normal speed, simply go to the Empowering Technology "Widget" and crank the CPU speed back up. I had Vista on my laptop and put XP on it. It runs lots faster with XP and 2 GIGs of ram. Hope this helps!
