Laptop adapter and computer interface contact bad DIY repair?
May be the interface or socket of the core magnetic induction bad, you can change one.
I do not know the adapter interface is broken, or the computer's jack problem. General adapter interface problems more, the adapter into the other notebook to try. If it is a computer jack, to repair their own disassemble, remove the notebook keyboard, jack connected to the motherboard, their insecurity, ruined the motherboard is not good.
Depending on the notebook brand model, the adapter and host interface may be different. In the existing notebook, the more common for the circular interface and square interface.
Open the notebook, the notebook interface removed, usually 1-3 screws fixed to the electronics market to find the corresponding interface head, the welding or connection fixed.
If the adapter, the interface type of electronic market a lot, buy a back, the original thread cut off, re-welding and sealed with insulating tape, of course, may look better than the original look.
