The AC adaptor goes into the AC socket, NOT the computer connection. The Computer connection is DC and comes from the DC side of the Adaptor. If you mean the DC socket has broken, then you need someone to replace it inside the computer.
If the AC adaptor has failed, you can buy a replacement ( 19V 3.16A 60W AC Adapter).
See the Manual http://downloadcenter.samsung.com/content/UM/201408/20140829115137641/Win7_Manual_eng.pdf
If you are using the correct adaptor then the most likely reason is that the socket where the adaptor plugs in has broken away from the circuit board and will need to replaced/resoldered.
if you need a socket Google : Yamaha PSR power socket ( KPA3 / PA130UK / EPA3 ) (LB30226R)
OR if you have used the wrong mains adaptor and the polarity was reversed you may have damaged the diodes / voltage regulator on the power input.
The charge ports do break loose. If you know somebody who knows how to solder very well they can reattach it. Some times the copper PC board traces pull up with the legs of the mini USB port and need to be connected with some fine wire. This should be no problem for a decent electronice tech. Your other option is to find another phone in which to charge the battery. The battery is a BR50 and I charge them off the phone with two tiny alligator clips attached to the leads of an old charger. These are about 800mAh so a dead battery will take an hour or so to charge. The voltage of a fully charged 3.7 Volt Lithium Ion battery under no load should be about 4.05 volts. You can check with a volt meter. Removing the main board to access the charge port will require a T5 (Torx bit) screwdriver. Lift off the battery cover pry the plastic piece off the bottom and remove the screws. Then carefully pry the two flex cable connectors off from under the board. Lift it out and resolder the charge port. Repost if you are having any troubles.
You have either a faulty connector plug on the power adapter which connects into the laptop or the loose power input socket on the laptop is faulty. This is because you need to press the connector upwards to make electrical contact.
Test the connectot plug on the power adapter with a multi-meter, wriggle the connector to see if your get the voltage to fluctuate, if it does not then the connector is OK anf the fault is in the laptop power input socket.
If the fault is in the power adapter plug or the laptop's power input socket, this can be repaired, a techo would have no trouble in repairing these faults.
In some laptops the power socket (DC jack) is soldered to the motherboard. If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.
If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.
The laptop would have to be taken apart and the DC connector resoldered.
This would cost $75 - $100. Enter your zip code in the box on the right hand side of the FixYa page to find someone close to you. If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
Usually what happens is that the ac connector on the laptop get loose. It happens when you wiggle the ac adapter out rather than pulling it/pushing it straight in. You can check if this is the problemsby
powering off the laptop. Insert the ac adapter. just slightly wiglle it. if it wiggles at all, then this is the problem. It can be fixed by resoldering the connector back on the System board, which entails taking the laptop completely apart.

hi
no need to disassemble the device all you need is long thin tweezers
take the battry out
look inside the socket (with light) and find the silver\gold connection battry tabs
with the tweezers elevate the tabs for better connection
on the lid is a spring like (push the battry in place)
elevate it too
if this wont work
buy a new battry before taking apart the device
good luck
