Take the back cover off your laptop there are 10 screws holding it in place .Once you have it off look at each side for the hinge support There are 2 torx headed screws on each end I think there torx 8 but I'm not sure. to find them you may have to move a wiring harness for your screen cables on one end and there's some sponge covering the other end .Tighten them to snug but be careful not to over tighten them .They are also screws under the black cover on the hing itself snug them up as well if needed. Hope this helps
