    ThinkPad Thunderbolt 3 Firmware attached,extracted from lenovo updates,plus links to driver downloads.Some models have 2 different firmwares, TBT.bin and AssistTBT.bin for the models that support or have bios assist enabled. NOTE: All the FW will need padding out with zeros using a hex editor to the size of the chip.

    Systems may experience any of the following symptoms:

    USB-C port not working
    Intel Thunderbolt controller not visible in the OS/Device Manager
    USB-C or Thunderbolt docking stations not visible or having connectivity problems
    HDMI output not available
    System battery not charging with a USB-C power adapter connected to the USB-C port
    Intel Thunderbolt pop-up error message
    Intel Thunderbolt safe mode error message
    BIOS Thunderbolt communication error or hang during POST

    These symptoms may occur after 6 to 12 months of typical usage.

    Re: ThinkPad Thunderbolt 3 Firmware

    Hello. I have a Lenovo T480s Type 20L8. I run in some troubles with it. In slow charges and the thunderbolt is not working. When the charger is conected it does not work on 20V. When i open the laptop and the charger is plugged in the laptop complains about the charger. The battery slowly charges when the laptop is off. I can`t manage to put your firmware on my bios. Can you please help? Do you think is a hardware or a software issue?
    Thank you in advance!

      The thunderbolt firmware is flashed to a different chip,not to the bios chip. You should test with another charger first. If you want more help with it start a new thread in the main laptop forum - https://www.badcaps.net/forum/forumdisplay.php?f=23

                Re: ThinkPad Thunderbolt 3 Firmware

                Hi i messed up my 25Q80 thunderbolt eeprom by thinking its the bios chip.
                I did make a back up of the original ( attached)
                but even when I flashed it back I still get the power adaptor not enough warning, so I think it didnt fix the issue.

                thinkpad x390 8th gen

                appreciate any assistance to get it back

                thanks

                      Hello,
                      I have some issues with this model.
                      Lenovo Thinkpad x13 Gen1 Type 20ug sn:PC-28QECQW

                      The type c connector is not getting 20v, only 5v
                      The second one is working fine.
                      It's a firmware issue? Can someone help with the bin file?

                              If it doesn`t work try flashing the 1MB zero`s file at post #1 and -> https://www.badcaps.net/forum/showpo...70&postcount=3

                                    Hi, I have a T480 not charging batteries, I try another charger but the problem is not charger but I think is the thunderbolt. I follow some tutorial to flash the correct firmware by a ch431a. First I erase the chip, than flash with a null.bin and finally flash with the TBT.bin padded, but the laptop continue to not charge the batteries. The problem is the two batteries are empty and I can't boot the laptop. My question is: is necessary, after flashing, to boot the laptop to complete the process? So can be this the reason why the thunderbolt not charge batteries also with the new unbugged firmware?

                                        I use HEX Editor Neo on Windows. Edit - Change file size - 1024kb - save. It will change the size and fill the rest with zeros.
