That some cable or contact is failing. Given how cheap this part is compared to a new laptop, why not replace it?
If you feel it's the laptop "jack" type "laptop jack repair" at google.
Ok, I have been having problems with my charger not wanting to charge my laptop. Some days I would have to move the charger around to make it charge and some I just have to plug it in. But now, I have tried everything such as turning it, ect. to try and make it work. Is this a sign of having to get a new charger? (I'm at half battery now)
