Hello everyone, I hope you're doing well.

I need your help, please. I'm trying to understand if it's possible to remove the supervisor password on a Lenovo ThinkPad T14 Gen 4 (AMD version).

I've read several threads on the forum, but I couldn't figure out which method actually works for the T14 Gen 4 AMD. Some mention using a motherboard jumper, others talk about a special USB key, and I also saw something about using an SVOD4 device.

To keep it simple: Is it possible to remove the supervisor password on a T14 Gen 4 AMD?
If yes, what is the correct method to do it?

If needed, I can provide the required information such as BIOS details, dumps, etc.

Thanks in advance for your help!

Re: ThinkPad T14 Supervisor password

Has anyone read the EC IT8300 chip, from thinkpad T14 AMD, using RT809? Mine is giving an error and even with everything right, would there be any other modification on the board that I do to make the reading? I don't have vertyanov and I don't have svod.

Has anyone managed reading EC IT8300 on thinkpad T14 AMD, using RT809??

Hi everyone, I have a thinkpad T14s G4 with supervisor password, I read the chips with the RT809F programmer and it is possible to remove the password with this programmer ??

Hi! I am excited to learn about these chips. Can someone tell me if one of these chips is the embedded controller with the supervisor password stored on it?

This is on a NM-C801 motherboard from a T14 Gen 1 w/AMD Ryzen 7.
ITE IT8300FN
or
ITE IT5261VG-256

Thank you!

Password in SIO. you need vertyanov successor or Svod 4 programmer.

Someone wrote here that patching was not doable on 32MB BIOS chip.
I have a T14 gen 1, but it has a 16MB BIOS. Any chance?
I see some people that after trying the patch only got black screen. I don't want to risk, as the machine is usable. Although I could write the original file later if that happens.

Hello guys
There some informations about lenovo thinkpad new generation laptop
I1st option is usual jtag
2nd one is that you can modify bios bin in certain lines addresses and those modifications can delete the password
I found this on the internet maybe it's possible maybe it's not
If someone Can confirm that

Modifying the bios is only possible on old models. This topic is for the T14 which requires MEC1663 JTAG and a programmer compatible with it
