    IBM R51 touchpad not working

    Hello
    I have an ibm r51 laptop which had a little "coffee break" on the touchpad and now the touchpad and the left mouse button doesnt work.
    It doesnt seem to have any cofee on any component on the touchpad or on the side of the board.
    Can someone tell me what to check?
    I couldn't find any schematics either

      Take the button apart and clean it.

          try cleaning the ribbon of t/pad and buttons, as well as connectors with something like Isopropyl. if you have not already done that
          any coffee get in that keyboard by any chance???
          I have seen bad keyboards do some funny things to t/pads
          disconnect the k/board and see if there is any change in t/pad

            Good idea but the buttons that start the notebook have the same ribbon with the keyboard. So if I disconnect the one ribbon I cannot even start the notebook

              So give i all a good cleaning and let it dry for a couple hours. Then reassemble and test. Good luck.

                I try clean it with isopropanol alcohol but still nothing.
                Is there anything that I can measure ? acontroller or something?
                I can't find schematics for this laptop.

                  You can check the flex cable, connector, soldering. Clean with isopropyl alcohol is always good idea. Sometimes I use WD40 to impregnate contacts against corrosion, it cleans them too.
                  Found the schematic here.
                  IBM R51 schematic.

                  [Mod. Edit] Do not attach schematics here at Tech section please.
                  If you want to add a schematic, find an existing thread at Schematics requests sub-section to do it, or if such doesn't exist create a new one.

                  CF-20 Toughbook (mk1) Trackpad/Touchpad and USB ports not working
                  by MichelinMan
                  Hey guys,

                  Just purchased a CF-20 (mk1) supposedly was all working. However, the seller had done a fresh install of windows 10 but did not install any driver. Seller was adamant the trackpad/touchpad was working.

                  The touchpad/trackpad does not work. No led lights near the trackpad. The keyboard works, the USB 2 port on the base does not work, The USB 3 ports will recognise a USB 3 flashdrive but did not recognise a USB mouse. The ethernet port on the keyboard section works.

                  The USB 3 port on the actual tablet section works with no issues.

                  Macbook A1706 touchpad and keyboard not working. Please help
                  by B2L_Repairs
                  Hi guys i am new to macbook repairs (i mostly do microsoldering on iphones and android devices. I need your assistance with macbook a1706 (touchbar edition) that came in without touchpad and keyboard functionality. External keyboard and mouse does work but the keyboard and touchpad on the macbook does not work. I changed the touchpad flex, also replaced the touchpad but the issue persisted. I then measured voltage on the board and found that PIN 44-50 of the touchpad connector (J4501) got 11.2V instead of 12.6V. Those pins required 12.6v and they get their 12.6v from PPVIN_S4-TPAD_FUSE . I measure...

                  Lenovo Yoga touchpad buttons not working
                  by Zinput
                  I have a Lenovo Yoga/Ideapad 910-13ikb. It is specced with the Core i7-7500U and 8GB of RAM. The problem is that the touchpad buttons do not work anymore after the laptop was exposed to water. The touchpad tracking works, and I am able to use it with gestures, but I would like to fix the buttons. So far, I have tried reinstalling the Windows Precision Touchpad drivers, trying several different Linux distros, resetting BIOS, reseating the touchpad ribbon cable, cleaning the motherboard with an electronic contact cleaner, and replacing the touchpad. There are no signs of corrosion inside except...
