    I watch a lot of repair videos from bigger repair channels, it's great to switch it up and watch small channels.

    I am happy for the customer and for you because you managed to "dodge" that bullet, the touchpad will be installed later when it is available on the market. Congratulations. Excellent work Mike. Thank you very much for sharing.
    PS: I like those clients who "bet" on the rescue and trust you to do it. Do you remember who sent you a "surface" laptop from Malta? Another good bettor. All the best from Mexico.

    Good morning. Congratulations for the succesfull repair! As far as touchpad is concerned, I believe that it is not a HW problem since when you were in BIOS menu it was OK. So PCH is working and it can be rule out. My suggestion is to try a Linux live distro on USB stick and check the touch pad with a different OS. If touch pad is fine with Linux it it a WINDOWS problem (compatibility, perhaps?). Good luck, fingers crossed! Regards from Italy.

    I had a similar problem with a touchpad not working once Win 10 loaded the Alps driver. I made it work by deleting the driver and let it be a simple HID device. This was on an 8th gen with LTSC

    Excellent video and repair Mike. Very powerful come-back 😉 The touch-pad since it's working on the BIOS it should be some higher level logic that doesn't work. Did you check if the touchpad board has some FLASH IC on it ? For the reworking, could you please elaborate on temperatures a bit ? What temp you set on the hot plate ? Did you take measurements on the PCB surface ? What was the target temp before you start pushing hot air from the top ?

    • @fairrepair_en
      @fairrepair_en  5 місяців тому +3

      The truth? I don't use a temperature Sensor on the board anymore but work according to my feeling.
      Hot plate set to 200°C, pre-heating the board for 15 Mins, Hot-Air set to 350°C 50% Airflow with a fitting Nozzle for the BGA size and let's go. Observation with microscope till I am convinced, PCH is in place, done.
      Did not find anything useful on the touchpad PCB but checked every single single line and component on the mainboard without success. However, I am done with it and it's okay. I gave everything I could and a 95% win is still okay for me. :)
      Best regards

      @@fairrepair_en I know the feeling. I work here with some DELL corporate laptop boards and even if some times a finger print sensor (for example) doesn't work, it's fine as long as the board posts and loads windows. I'm going to try my luck with big BGA and I'm trying to collect as much information I can, so thanks for the info 😃 As for cleaning ME region, I can help you too if you can't find someone else available. Have a nice day Mike!

    Awesome. Did I miss where you sourced the PCH? 👍

    • @fairrepair_en
      @fairrepair_en  5 місяців тому +2

      Nope, i forgot to mention. Comes from SUHMS ( Shenzhen Hong Ming Electronics Co., Ltd. / AliExpress ) Sold as "new", since from my experience it's the best chance to get a working PCH without the bootguard fuses already triggered.

    congrats on your repair, but I confused in 27:00 - 28:00 you have picture on laptop, is this after you replaced clean ME region or not? thanks

    • @fairrepair_en
      @fairrepair_en  5 місяців тому

      This was before the dirty ME was cleaned. The point is, that it needed way too long till it shows picture, even after second and third attempt (without removing power) it was too long. This is a typical cause of dirty ME Region.

    Looks like you need the right driver for the touchpad if it works outside the OS

    • @fairrepair_en

      Yeah, the world would be perfect if this would be the issue here. tl;dr: I've tried everything I could think of to rule out a driver issue.

    when you replace EC chip, you don't have to program it ?

    • @fairrepair_en
      @fairrepair_en  5 місяців тому

      This is true, except in some case where the EC sources the Code from the main BIOS like in this case. Is the same with most ASUS boards. Best regards.

      All good, fume extractor is built-in to the ceiling. 👍

  • @justinc9991
    @justinc9991 5 місяців тому +1

    Your first attempt failed because you use too much flux… flux is “boiling” and releases gases. When this happens, if there is too much, it will cause the balls to shift and create shorts…. Good luck!
