Once no power supply is installed into the computer, place the new power supply into the computer and screw the screws into the back of the power supply.

2 X IBM T41 laptops, both with extremely dim displays. I'm guessing the inverter has gone, any thoughts? Any availability ideas for replacements for either inverter, ot complete LCD assy, including...


When the invertors fail, it is common to be completely dead not showing a little light.
Maybe they have both failed but I would check the power save settings first.
Hope that helps.

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.

Try to remove your keyboard and fix it back. Seems like the keys are getting struck. You could search in Youtube of how to remove and fix the keyboard back on the laptop.

Ibm thinkpad no power with ac power adapter but works with battery


If prior to this it works intermittently with the AC adapter, it means the connection from the adapter power unit to the motherboard was lost and this is a typical problem with the Thinkpad. It needs a re-soldering job and not something that one can do without a proper repair manual on how to open the laptop. Try googling your problem and find out if someone has the same experience and managed to resolder by him/herself.
