Hi, My laptop is an HP Pavilion dv9000 which I bought like a year+ ago. I use it for school since I am a computer systems major. My question is that I want to install my Win7 ultimate 64bit on it and I know it will be a fresh install and wont have the factory programs and such. So with this being a clean install will my laptop still work? Like will it recognize charging when I plug it in, will the touch pad still work pretty much will my laptop be the same laptop but with a fresh install of win7? I cant have my laptop not being functional.
