how much it cost and d.i.y or else ?

Good to know but mine was HP G4 it look awful to open alot of screw , last time service sent to individual (repair man lol) and the laptop missed something inside the screw probably , and the keyboard seem abit loose at top place , later sent to Vital for thermal paste and cleaning , and ask to topup wht ever missing like screw inside but nothing has improved . I dont know how to open i have got an iron hand lol i can twist and break mine .
