Both laptops I have suck. There is a Windows 7 HP laptop with tons of issues (sound is broken and completely unusable, blue screens on boot, and USB mouse rejection) but it is overall the best computer I can use for gaming, so that's where I keep Blockland, Steam, etc.
I also have a Windows 8 ASUS laptop, but it runs like a potato, freezes the browsers constantly, and games run on a slightly lower fps. Overall though, no parts are screwed up afaik
