    IBM THINKPAD T43 Remote Power Switch

    Here is how to mod your IBM T43 Keyboard so that you have remote power off...

    UPDATE: 26-MAR-2010

    In trying to make the laptop even better, I've made some changes. Now I've totally ripped out the KeyBoard Circuit and directly soldered to the MB Header. In addition, I've removed the Modem harness, and soldered directly from the Keyboard Header to the Modem Socket. This allows for a simpler On/Off connection. See Photos

    You must remove the modem harness if you plan on using the modem socket to connect the switch to... which is much cleaner than wires hanging out. This also only allows for On/Off. You must make sure your power management console allows for shutdown when power button is pressed. Have fun!

    Here are the updated Photos first...













    I hacked apart my T43 keyboard, but before I did that, I installed VNC server as well as setup a static IP address so that I can use my IPhone to sill do what I need to (or my REAL laptop).

    First I ripped apart my keyboard to find the traces to the ON/OFF switch, simple, followed the ribbon cable to the pins. Verified with an continuity tester (VOM) and found the pins that were used. Soldered 2 wires to it and done. Video Included at the end.... here are the pics

    Hope this saves just 1 keyboard from the fate mine had... the T61 was a sample pic of what it looked like before I started.















    AND

    The YouTube video to prove it works.

    Hey dude, I have a ThinkPad T60 that i'm trying to use and destroyed 4 keyboards today . I found the last two pins on the ribbon cable are for the power button and soldering just doesnt work for me. Are there headers on the board itself other than the keyboard plug to solder the cable to? Thanks in advance

    Final Install board

    Well I've ripped this down to the bare minimum necessary to run. I'm still using the Cardbus for my network card... that will get yanked as well as the Cardbus adapter as soon as my USB 11g/n dongle comes in. Also for the hard drive... I'm considering a USB drive, but with that the camera, GPS, and Wifi dongle... may be a bit of a stretch. If that fails, will get a 2" 2.5M - 2.5F adapter ribbon to flip the drive over on the same footprint... Note power switch is soldered to the Modem socket, and VNC is running to be able to control the machine at this point. Looking for a VERY SLIM touch screen that I can embed in the middle flip-up cover on my Sonata.. that would be cool!

    Here are the pics

    Soldering

    I think your stuck soldering... I can't find any place on the MB that allows for a power switch other than on the header. Soldering is simple and cheap even if you don't have an iron... RS has a small kit that is perfect, and you really can't f- it up by soldering to the ribbon instead of the MB. Going to the MB is a bit tougher and you'll need a fine point on the iron as well as a good eye plus thin gauge wire pre tinned to make the connection quick and pain-LESS!

    Good luck
    Don't let 'The Brotherhood' get you down. Just video them and make fools out of them! They Never expect to be caught on video.

    Hi,
    I have installed a T60 as well. Mine has no screen, just the base and keyboard. I also ruined a few keyboards and found out that soldering was impossible for me.

    I removed the top black panel off the keyboard and removed the on/off button. I then used 2 thin gauge wires and fixed them the the printed curcuit under the button by using conductive silver paint from here.

    http://www.maplin.co.uk/Module.aspx?...C=SO&U=strat15

    I then hot glued the whole button area to keep it stable. Been in the car for 9mths now and still working fine. :-)

    Good luck!!

    Please help

    I got a t60, took apart kebyaord, followed tracks to make sure where they went and found out they go to pin 0 and pin 1 on the ribbon connector(THE PART that connects to membrane)

    Plug in it. put power in, touch the two wires and nothing.

    Please explain if you know what is the problem?
    and aslo how come u soldered under the laptop (i would assuome on the dock connector) and also did the keyboard ribbon mod?

    if you have the pinouts for the laptop dock connector please let me know.
    THanks m8t, really need to get this done...only thing stopping from puttin it in the car.
