ThinkPad X13 Yoga Gen 1 bios

[ticbra]

Hello everyone,

I need help removing the supervisor password for a Lenovo ThinkPad X13 Yoga Gen 1 laptop (10th Gen Intel).

• Model: ThinkPad X13 Yoga Gen 1
• MTM: 20SYS02J00
• S/N: R90ZRW40

I have attached the ZIP file with the original, untouched dump.

Could someone please help me clean/patch this file?

Thank you in advance!

Hi again,

Either the SVOD4 or the Vertyanov successor would work fine, just pick whichever one you're more comfortable with (watch a few YouTube videos beforehand)
Also, there's no need to solder wires. You can read the KBC directly through the keyboard connector after matching the pins correctly
There's already a schematic available for you here > Lenovo ThinkPad T14s Gen1 / X13 Gen1 schematic - Badcaps
But I think that chip would auto-detect after plugging in the programmer left of the keyboard
Of course You'd need to Select Nuvoton, 1.8V, 256KB and read ID

Hi, the password is rather stored inside the EC/SIO chip (NPCE388?)

Hi sparo,

Thanks for the warning! Yes, the dump I uploaded is the main 32MB BIOS, but now I see that the password is completely locked inside the Nuvoton NPCE388 EC chip.

Since I want to do this repair myself and expand my workshop tools, I would really appreciate your advice. Which EC programmer do you recommend buying for reading/writing these types of Nuvoton chips (Vertyanov JIG, SVOD4, RT809H, or something else)?

Also, what is the best way to connect to this NPCE388 chip on the X13 Yoga Gen 1 motherboard? Do you read it directly via the keyboard connector (JTAG/KBC), or does it require direct soldering to the chip pins?

Any advice on the programmer and the unlocking workflow for this generation of ThinkPads would be amazing. Thank you for your time!

Your dump is corrupted.
Try to read two or three times (or more times) until at least two readings have the same CRC.
There are plenty of free online CRC calculators or install 7-Zip free and you will have CRC calculator in Right-Click menu.
