LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

You need a bios chip programmer, you can use CH341A (first make sure stock software does not corrupt reading/writing, if it does, use alternate software), EZP2019 or other programmer. Besides programmer I also recommend a SOP8 clip to prevent desoldering/soldering of bios chip. Some ThinkPad models use a WSON8 chip, which would prevent the use of clip, in this case you can solder wires from chip to programmer PCB adapter.
What’s the ThinkPad model number?

it s t480s,

one of our office worker was given this to do remote work during lock down, he had a problem with his ssd, so when i changed the ssd, and tried to boot with usb for new install, i couldnt do f12, went to bios found SVP so cant change anything (edit: worker doesnt remember setting it up, but we never put svp so gotta be someone from his house, or himself lying). I can use usb nvme enclosure to do the job one way or another but was thinking of finding out easy reset procedure. thought this was easy seeing no mention of bios soldering etc... anyways i think i ll look into your suggestion as a future consideration as well, i ll make sure SVP these laptops before handing them over to remote workers next time

It’s a relatively easy job, as long as you use a programmer with SOP8 clip (no soldering required). With some experience it can be done in 30 minutes or less.
In my opinion the most important step is having a backup of original BIOS (read chip and save file, do this 3 times and compare all 3 files to make sure they all match), before trying any patching of the bios.

i ll keep a note of this. and thank you for the help. problem is solved actually without needing anything else... worker provided possible passwords he thought set up. and i tried them with caps on and off, one of them worked... he set up with caps on so i tried by hunch and figured it out. but future issues i ll keep on this.. maybe buy a model with locked bios and figure out with the programmer for practice.

new user here.
so, as i understand, i need a bios chip programmer, desolder my bios chip, put it in the programmer, read it and upload it here. then someone can send me a patched archive that i need to write on the chip and will be able to bypass the password verification, right?

does it work for the intel T14 GEN 1?

i've been reading all the posts.
i seen some people talking about "self healing" bios on some models. Is the t14 one of those models? i haven't seen anyone talking about this specific model.
if it helps, my configs are
i5 10310u (vpro)
8gb ram

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Yes the t14 series are self healing.

Yes the t14 series are self healing.

So there is no solution?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

i don't even need the bios password, i just need to reset the 0199 error count. just to be able to boot again

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

@dinarte
To be able to reset “Error 0199: System security-Security password retry count exceeded” you need to get into Setup/BIOS with Supervisor Password.
