Suggest a Laptop for me.

Hello Lemmings,

My 5 year old gaming laptop finally needs to be replaced. I need a new laptop for programming and light gaming. I no longer game on a laptop but a desktop. Though being able to play even outside would be nice so the laptop should be able to play at least Team Fortress 2. I'll be installing a Linux distro on it. My budget is around 800-1000€. The screen should be 14 or 15 inches. The battery should last at least 6 hours while not doing anything heavy as video editing or gaming.
