You are right, most of the situations like this end up that the charging connector fixed / soldered to the motherboard get damaged because of shaking the connector when ever we connect and disconnect it .

Hello my laptop t41 power is not even flash but the adapter is working,am technician and i have troubleshoot allot.


I concur with what Diegotech stated.

To iterate further;

1) The DC Power Jack (DC IN), may have cracked solder joint/s on the motherboard connector, (Female), where the DC Power Jack plugs in.

Resolder

2) The DC Power Jack may be broken.
Center Pin mount, and/or body of DC Power Jack, and/or Outer Shell mount.

Replace DC Power Jack.

3) Wires from the DC Power jack plug to the female connector on the motherboard, may be bad.

Replace DC Power Jack.

2) http://www.machinaelectronics.com/store/buypart/IBM_Thinkpad_T41/DC-P001

Past this point it's a bad DC sensor on the motherboard.

Replace motherboard.

No light when charger connected to laptop.


You do not have to resolder the connection, the dc jack is attached to the motherboard via a cable and plug. You can purchase these on Ebay for under 20 bucks. Below is the link to the disassebly guide that will assist you.

This link here is for the DC jack...

I replaced the battery and adapter for my hp zt3000 and the battery wont charge, the pc turns on and works when plugged in but if i remove the plug the pc shuts off . its been plugged in overnight in hope...


It sounds like a broken power jack. to verify this remove the battery and leave the DC connector plugen in the PC, slowly move the connector where it plugs into the laptop and see if the power comes on when its at a certain angle. If it does then you need to remove the mother board from the computer and order a new DC jack and unsodder the old one and re-sodder the new one on and that should fix the problem. If you and never soddered with circut boards i would let an expert do it. it will probally cost $100

Hope this helps!

The pin on my power connector is broken


If you are referring to the pin on the AC brick (the part that actually plugs into the wall), then you don't fix it. Due to risk of fire, it would need to be replaced.

If the pin is on the laptop itself, then you would either need to replace the motherboard or obtain a DC jack and sodder it to the motherboard after removing the old one. (Generally, the DC jacks are not field replacable.)

Toshiba dc connector


Hi,

If the laptop still works, then there would be no need to replace the motherboard. The DC jack is replaceable/repairable. What would be more challenging is the disassembly and eventual exposing of the bottom part of the circuitry where the DC jack is soldered into. Often the DC jack would have at least 2 solder point (not more than 3). This might interest you.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
