Question about Computers & Internet
My dc power jack is broken. Can this be repaired?
Is the connector on the power adapter that plugs into the laptop?
If so, this is an easy repair, purchase a new connector from electronics parts shop, cut off the old connector and solder the new one on the end of the cable. MAKE SURE YOU SOLDER THE CONNECTIONS TO GIVE THE CORRECT POLARITY ON THE CONNECTOR, OR YOU WILL DAMAGE THE LAPTOP.
If the power socket on the laptop is faulty, this repair is more difficult. The socket may only need resoldering on the motherboard or in the worst case a new socket replacement. Either way the laptop need to be dismantled to get at the power socket.
If you don't feel you can handle this, get it done by a computer repair shop or a techo friend.

SOURCE: DC Power jack broken
Looks like you're right, I did not see any Lenovo replacement jacks either. You might try looking at the IBM Thinkpad jacks for various models to see if you can find the same jack.
I've repaired 3 laptops with this problem. Rather than replacing the jack on the mainboard I wired a "pigtail" to the mainboard and then zip tied a female connector to the back of the laptop itself. I did this because the mainboards were pretty beat up from the heat the original jack produced as it began to loosen. The end result is not as pretty as the original jack, but it absolutely takes all the stress off the mainboard. Those computers will never have this problem again.

Take apart laptop and see what type of jack is on your system. There are two types. one is soldered on and the other is a module that connects to the motherboard with a wire connector.
If you have a soldered on type the you will need to de-solder it from the board then solder a new one onto the board. most ac jack issue just need to resolder it unless the jack itself is broken.
