Imagine that - a beautifull day, you are sitting comfortaby on the couch, you are opening the laptop lid aaand one of the hinges cracks... What a disaster you think, you have to pay outrageous cost for repair in the laptop service shop... Buuut there is a quick fix for the problem, all you need is a screwdriver and 1 hour of your time. :)
Dissasemble the laptop. Locate the broken insert for the metal bushing which holds the hinge and remove it. Drill a small hole in the center of the cracked plastic insert.
Step 1: Metal bushings
This is the metal bushing which is placed into insert on the plastic case of the laptop. It is almost impossible to glue it, because some laptop manufacturers use special plastic for the laptop case, a plastic which does not stick with most glues, also there are a lot of tension in the place where the insert is located and after several times you close and open the laptop lid, the hinge base will crack again. Notice that this little thingy have thread from end to end.
