Hey guys! I was just wondering if any of you know a reliable website to purchase replacement computer keys? I just opened up my laptop after my dog had hopped up on the bed, and one of my keys is missing. the left Ctrl key for my Lenovo G50-45 is gone, hinge too, I can't find it anywhere. no sign of it. I've looked around at some sites and I also don't know which one to trust. I also don't really know which hinge type I need... I think maybe L 72. Anyway, if you guys know a reliable website, I'd greatly appreciate it.
