I have literally bought a Lenovo G580 within the last 24 hours and have already noticed the HD 4000 igpu isn't that grand. I wasn't expecting miracles but I was on a budget and had to get a laptop there and then for work. This was all I could afford that met the criteria.
Basically I want to know if there is any chance of me being able to (easily?) upgrade the graphics card in the future. I don't really want to void the warranty by opening it up to check the space requirements but don't really know where to look for such information.
