HP EliteBook 810 Intel i5 Convertible Laptop

I bought one from here but received the shipping from AST. The laptop is fully worn-out and scratched, and its cover is even discolored. It has after-market AC adapter, which is over 2 lb., rather than the original slim adapter as the description stated. Also, the WIFI is not working; it drops signals once every few minutes. The unit is unusable and should go direct to trash can.
