    Lenovo TP00095C – “G” marked component fell off during USB-C repair, need ID

    Hello,
    I have a Lenovo laptop board TP00095C with a broken USB-C port. While replacing the USB-C connector, a very small black rectangular component with a “G” marking on it (located on the back side) came off.

    I still have the component, but its pads look damaged. The pads on the motherboard itself is not affected.

    Could anyone help me identify what this component is, and if I can reuse it or if it should be replaced?

    I also noticed that the other identical components around it all look slightly tilted/crooked, but they are still well soldered.

    Thanks in advance!

      They appear to be ESD protection diodes. The circuit should work without them, but you won't have continued protection from ESD.

          For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

          Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

          Hello everyone,

          I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

          This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

          I have opened the laptop and identified the main BIOS chip...

          by nikolayu
          I have Lenovo ThinkPad X1 Nano Gen 1 which is not charging on 1 usbc port (the one that has mark for charging).
          When i connect usb it switchs to 20v but no current draw (only 0.02a) and orang light is on. In windows it shows that is charging but percentage is dropping.
          Other usbc is charging fine,

          I installed lates bios and firmwares for thunderbolt and battery.

          Could be faulty JHL8040R controller?

          Lenovo Ideapad 1 15IGL7 NM-E791 Rev. 1.0 fell down when switched on
          by osbln
          Hello everyone,

          I like to repair everything I can get my hands on.
          A friend gave me a laptop that fell down while it was switched on.
          Now the display remains dark and the laptop no longer boots up.

          Since my English is not so good, I worked with a translation tool. Please excuse me if something is not translated correctly.

          Normally this device is not in a price category where you have to grit your teeth, but I really want to find the error and learn something in the process

          Details of the device:
