Problem with power socket on the laptop, it may caused by a dry solder joint and needs to be resoldered or the power socket may be faulty and needs to be replaced. Either way to fix this, it requires the laptop to be dismantled to get at this power socket. Get a quote to repair, as it could cost a few dollars.
If it is a faulty cord/plug on the power adapter, this can be checked with a multi-meter. When you connect the multi-meter probes to the power plug the voltage should be steady and the reading should be slightly higher then the voltage that is printed on the label on the bottom of the power adapter. If the voltages fluctuates as you wriggle the plug then you have a broken wire in the plug. Replacing the plug would not cost much.

How do you take out T42 IBM broken power jack in order to put in a new one


you need to remove the keyboard then the upper casing... if you have a modem, remove it to get more work room. you should be able to unplug the power connector off the mainboard (the wire between the power jack and the mainboard) and snap the old jack out of place. be careful not to break the board or anything while doing so, though it should not be hard to remove the jack since it is not soldered. best of luck

My ibm think pad t40 is not switching on


Hi
Assume you are trying this on battery and mains?
1st thing is to check if the AC power adaptor is giving out any power, which you can do by obtaining a multimeter and setting it to 50 volts DC. Place the positive probe in the centre of the adaptor plug and the negative against the outside of the adaptor plug and see if you get a reading. this will confirm that there is power getting to the laptop

(NOTE: THIS IS TO BE TAKEN FROM THE DC END of the power adaptor NOT from where the kettle lead AC source enters the adaptor.. if in doubt, get someone who is competent with using a meter)

2nd, is to check that the power button is not sticking and that the small plastic pin between the laptop body and the screen ( I think these have one) is not stuck, preventing it booting

3rd, If you are getting power by AC to the laptop, check the condition of the DC jack socket, if it is loose, appears to spark whrn the jack is plugged in or crackles, this will need replacing

4th, If the above do not work, it is possible that the main fuse in the laptop has gone...specialist repairers job.

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.

Two examples, of a place to buy an IBM ThinkPad T41 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.

Here's the website consumersupport.lenovo.com , it will just ask you to type in the serial no. of your machine and the exact type and model and from there it will give you all the drivers for your laptop. Hope This Helps

Power connector of T40 think pad loosen


If you can't charge the battery and you know the battery is good, hook up just the ac adapter to verify that the laptop can turn on without the battery hooked up and if your laptop turns on then you know both are good.

At that point I would say since its not charging then it could be that the dc jack has some bad solder points on the bottom of it and need to be resoldered. Sometimes if the solder goes dry and cracks just a bit if can cause the adapter not to charge the battery.

If that doesnt fix the problem the the motheboard is bad and would need to be replaced.
