My old laptop's battery wouldn't hold a charge for more than 15 minutes, so I bought a new battery, and the new one had the same problem, so it was the laptop itself not charging the battery anymore. I need a laptop for school(which I am starting April 26th) so I decided to get a powerhouse instead of just a basic laptop. Here are the specs of it:

cpu: intel i7 720qm @ 1.6ghz
ram: 6gb ddr3 1300mhz
gfx: ATI Mobility Radeon HD 5870 1gb gddr5(best laptop gfx card you can get without going SLI/crossfire)
HDD1: 500gb 7200rpm
HDD2: 500gb 7200rpm
os: windows 7 home premium 64-bit
screen size: 17.3"
mouse: Microsoft Sidewinder x8
