This system does not work for 32Mbytes. This system is only valid for 16MB. I have done it many times.

hi everyone, my laptop Lenovo Thinkpad X1 Nano Gen 1 Bios screen is stuck at 100%, I found some dumps and flashed the bios, it works but the SuperVisor password is stuck. Can someone help me? This is the dump I used, not the original dump of the machine

Hello,

I have a laptop with supervisor password set which I don't remember. I tried the autopatcher (both versions), but it seems it doesn't work with my model. The keyboard status LEDs light up, turn off again, then nothing, and after about 20 seconds I get multiple beeping tones.

ThinkPad X1 Extreme (v1)
Type: 20MF-000TGE
S/N: R9-0RVL8E

Can you help me remove the password?

I managed to solve this by myself. Using the BIOS from https://www.badcaps.net/forum/troubl...15#post3579915 worked with the autopatcher.

I have a Lenovo T490S, can you help me REMOVE THE SUPERVISOR PASSWORD? Type: 20NY-S34L00 S/N PC-1FV4Q1 20/03 Thank you in advance

Can someone help me? When I use the autopatcher, the computer starts beeping and does not start the BIOS.

I have bought a thinkpad t440s

i7
it is bios locked, i CANNOT buy new motherboard
which chip do i need to dump? i can buy clip to do this, i have a t48, but have no idea where this mystical chip is or where to find it

after it is dumped, can i use the util from the first post or do one of u have to do it?

this computer is worthless to me without bios unlock, i would be better throwing it away if this does not work

Right above the RAM dimm.

Hi!
I have problem with locked T540p
With original (locked) 4MB file works fine, with the patched nothing just blank screen and power led on.
Tried to read again, repatch, rewrite, no luck.
Patcher completes with error "Looking for volumes to patch... [1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h): Not found... Skipping."

What is that?

Problem solved with 4MB file from post #11 of another thread.
Seems like AutoPatcher is unable to correctly patch the 4MB file and produces the above error, this user manually patched it and works like a charm.
Keep in mind that motherboard needs the LAN & USB daughterboard to be connected in order to power up, otherwise doesn't boot!
Thank you all!

Just preparing for when I am able to get access to a programmer. Might take a couple of weeks to get it , my country is not so easy to get deliveries quickly, figured I'd get this part of the process done if possible.
