    Default Custom Power Adapter

    Ok, I have an IBM Thinkpad 750c, and I would like to make a power adapter for it.

    Please, DO NOT give information about ones on eBay, if I really wanted to BUY one I would have already.


    What I am concerned about is, what the hell is S...

    And could somebody maybe help me with what cable I could use from a power supply to make this work from an old power supply.

    I have this information about the actual power supply for the laptop
    Input Ratings: 100-240v 50-60Hz, 70-80VA Output Ratings: 16V 2.2A

    so if i understand you whant to build your own one first i need to know how much is the voltage of your socket if u use 230 V or 120 V. I'll need some time to create a plan and test it.
