            Hi, I'm new to this. I've the same laptop and I want to remove the Supervisor Password from the laptop. From what I read from the guide, it says I may need EC Flashing instead of Bios? So do I still need the BIOS dump?

            Also, what type of chip does this laptop has for BIOS or EC? I don't have a programmer yet, RT809H is quite expensive. Do you think RT809F will do the job? Thanks.

                          May I know if this is the BIOS dump? I thought we need to use EC flashing to remove the password for Thinkpad X1 Yoga Gen 5? Thanks for the clarification!

                            Lenovo Yoga gen 5 password removed. EC bios can be copied from the main bios from A00020 - A4001F; just erase the EC firmware and flash with the data from the copied data from the main bios in the offset as mentioned and attached is the configuration to use with RT809H.
                            0. GND 1. TMS 2. CLK 3. TDO 4. TDI 5. RST.

                            I do hope this one helps the forum or whoever has been trying to unlock the yoga series.

                              Where can I find the information about copying the EC Bios from the main bios from A00020 - A4001F? Thanks.

                                  I've already read posts about reading/writing the EC by the programmer and bought the RT809F to try and do that. However, I haven't come across the A00020 - A4001F part, I thought that's new information that I missed?

                                  Anyway, I attempted to remove the 10k resistors and accidentally knocked off some other resistors while doing that. I'd be grateful if anybody can help me identify the size of the resistors labelled 1 and 2? Also, what is the IC labelled 3? I moved it as well, not sure if need replacement? Thanks for your help!

                                      Thanks for the info. I made it worse and moved more resistors. I'm going to see if someone can help me to do it instead. However, I need to know the components labelled in the photo. Can anyone please help?

                                      Also, may I know how did you find out what components those are? Can I have the schematic as well? Thanks. I've one for T490s and X1 Yoga Gen 6. Please point me to the right page, if they are compatible. Thanks a lot!

                                        Schematic requests, if you hadn`t noticed, are in a seperate sub forum. Use the forum search, it might be posted already.
