The hinges on laptop computers that connect the screen to the keyboard platform are used often and are sometimes poorly manufactured for their use. Even though it may sound scary to replace the hinges, it can be done with patience and in no more than twenty minutes of your time, although your computer will be out of commission for about 16 to 20 hours as the welding securely dries. Please read more for instructions.

First, unplug the computer and remove the battery pack.
Removing the front bezel. First, locate the screw covers on the front bezel. They are covered in a soft rubber. With a knife, pull them off, and with a screw driver remove the screws underneath the screw covers. Next, remove the front bezel by snapping it gently out of place.
Remove the notebook screen. The notebook screen is attached to the back bezel by bracket screws. With the screwdriver, slowly remove the bracket screws starting from the bottom and working to the top. Lay the screen down onto the keys, preferably onto a soft cloth. The video cable is attached to back of the screen with tape. Slowly remove the tape. If the video cable is attached to the back of the screen with hinges, carefully pinch the sides of the hinges and it should release. Carefully, set the screen aside.
Once the screen is removed, the broken hinges should fall off. If not, the back bezel will have to be removed and instructions on how to do so can be found in the maintenance manual for your laptop.
After removing the broken hinge(s) and cleaning the area, lean the back bezel at a five degree angel and find an object to support it. According to the directions on the JB Weld tube, apply the appropriate amount onto the hinge pin or "tube". Make sure to work the weld around and under the "tube." Attach the weld to the board that secures the keyboard, thus welding the back bezel to it. With a ruler measure whether or not the back bezel is in line with the bottom part of the computer so it will shut properly. If it is not aligned, align it.
Leave the screen at the same angle for about 16 hours, at the time specified on the JB Wells instructions. Once the time is complete, reinstall the screen and front bezel.
