The EC chip is not MEC is NPCX997KAABX. Not sure this chip is programmable. There is a 16 Mb chip. I have only board view for this model.

Ok, I didn't realize it was amd, I know that from 10th gen upwards in Intel CPUs it goes in kbc... but amd I have a doubt...

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello wonderful group, I need your wise advice, to start, thanks to you, I have finally managed to remove the administrator lock from my Lenovo T470 and it now allows me to modify the bios, now my problem is that when I connect the SSD m2 PCI NVME hard drive immediately The password lock appears, but when I turn on the PC without said hard drive there, it does let me enter the bios or execute USB boot, when I do the process to install the operating system, it does not recognize the hard drive, is there a way I can format and thus be able to install the operating system?

In an improvised way, using a mechanical external hard drive, I was able to install the operating system but only with that external hard drive installed. I would like your advice so I can use it in the normal way. I thank you very much for your attention and I hope for your help and suggestions to try to to be able to use my computer correctly.

What software, what programmer if you don`t give enough details how can anyone help .If you can`t make a proper backup you won`t be able to write to the chip.

When flashing a BIOS always make a backup first. Take 2 or 3 different dumps and make sure they are identical.
On Windows, you can use the command "fc /b" to check if two dumps are identical.
Make sure that the dumps looks good, i.e. not filled with 0x00 or 0xFF. After compression, if the file has a size of only a few kilobytes, the EEPROM was most likely not read properly.

Also you must post the laptop model number and serial number

your dump is wrong, if chipset is W25Q256 it should be 32Mb and not 16Mb. Autopatcher doesn't work for your model, open a new thread and dump your bios again, it's 1,8V chipset if it is w25q256jw, if you use CH341A you have to use an adapter for 1.8V.

Hello,
I need help with Lenovo T470P.

Man, I'm in the same boat with you. I have posted it here
https://www.badcaps.net/forum/showpo...postcount=2665
I'm leaning towards the idea that the EC firmware got damaged. I do not own the programmer that supports flashing the EC. So the plan is to send the board to a guy that can handle such stuff. I'll let you know if we succeed. If you manage to fix your system sooner, pls also let me know.
