    Lenovo c740-14in

    Hello all,

    I was replacing the USB charge chip and noticed that I knocked off a cap 'ext to it. I'm not able to find the place it was sitting.

    Does anybody have a picture of that area? It would be really appreciated!

    Thanks a lot!

      Not enough details in your post.

      Logic board number ? Silk screen details ?

      USB charger IC = U8 ?

                      Sure - see attached. Also attached the boardview file so you can do the same.

                          Thanks! Will look at it tomorrow!

                          Board view gives a lot more resistor/caps then what I have... Will see! Thanks again!

                              Some of the pads may be a 'no stuff' - we can compare against the schematic to be sure.

                                  Lenovo T480s usb-c charging port replacement - Knocked off a couple of diodes.
                                  by Nikolai Danylchyk
                                  Hi folks. As the title says, I was doing a port replacement on a Lenovo Thinkpad T480s and in the process of post-solder cleaning, I somehow knocked off 2 or 3 diodes (i think they are diodes) near the main usb-c. I can't seem to find what kind of a diode is that. I know it's ultra tiny and just has a letter "G" on it. Would someone maybe have a proper schematic for the t480s model? I can only find the non-s one and it's quite different to the "s". Would love to figure out what component that is.
                                  Thanks in advance!...
