Managed to re-attach one key, but the other seems to be missing part of its scissor switch. The pieces resemble a rectangular bracket and an oval bracket; the oval part is the one that went to the land of the lost. Luckily the keys weren't anything important (drop-down window and the right-hand Ctrl key), the missing key is more of an ugly annoyance than anything else. Does anyone know anywhere I can buy a replacement switch for my keyboard?

I found an Australian website that sold a higher capacity battery but it wasnt https and looked sketchy(actually all laptop battery sites look sketchy). I want the one thats supposed to last 8 hours or an even high capacity one
