    Yes, tried multiple monitors with different cables. Port looks perfectly fine, no signs of liquid damage at all. Tried the TBT update on Lenovo and tried installing multiple times with multiple restarts but still no luck.

        Go into bios settings and check if TBT assist is enabled or not. Backup the current TBT firmware , use a new chip. The firmware at post 1 needs padding out to 1MB using a hex editor.

            TBT assist was disabled. I have enabled it and tested it, still the same issue (I presume it is better to be enabled). Just to double check this is the correct chip?Click image for larger version Name: IMG_7117.jpg Views: 0 Size: 2.85 MB ID: 3813119

                I don`t know if that`s the right one, you can check with the schematic if there is one , or make a backup and post i`ll check it.

                    No worries. Do you know what the chip would be called/labeled on the schematic at all if I manage to find one.

                            Okay yeah, that's the right chip then. My replacement chips are on the way so will see how it goes when they arrive. Should be pretty straight forward.

                                            by TheUser
                                            Hello to everyone ,

                                            This is my first post here, and i would like to share with you a small story in case you can help me.

                                            Docker Type-C Gen 2 - Model 40AS. Was given to me by a friend for free ,but with the problem that you cannot use the video output ports.

                                            All ports work , USB , Ethernet, Type C ... but HDMI + Display Port don't work

                                            I searched on reddit and google for problem similar to that, and a LOT of people had fixed this problem by updating the firmware. So i tried , i searched and found 1.1.13 utility and 1.1.20 utility that can help...

                                            Lenovo ThinkPad X1C6 thunderbolt firmware request
                                            by TamFishe
                                            Hi there, I have a ThinkPad X1C6 which I got cheap from a friend as I've mentioned before if you decide on checking my profile, but it has issues, including both the bios and thunderbolt firmware bricked. So far, I got a 20KG bios from indiafix, however, I still haven't figured out how to fix the thunderbolt firmware issue ( I feel like mentioning that I've never worked with FL1 and FL2 files or with any Lenovo product and I'd wish to not brick something beyond repair. ). Can someone with this same model of laptop give me a thunderbolt dump of the chip (Winbond W25Q80 ONLY) and compare my dump...

                                            ThinkPad X13 Yoga Gen 1 (Type 20SX) Password Removal
                                            by zrb1qyvtv
                                            Hi,

                                            I didn't find a request for this specific SKU yet, but... I need the bios password removed from it.
                                            (The tamper protection triggered randomly one day)

                                            Here's as much info as possible about it:
                                            - ThinkPad X13 Yoga Gen 1 (Type 20SX)
                                            - SN R90YLACQ
                                            - Model 20SX002XGE
                                            - CPU 10th Generation Intel® Core™ i7-10510U
                                            - Lenovo-Support page for convenience

                                            And here are what should be valid EC and BIOS dumps (from an external reader)...
