Lenovo L560 - bios PWD

Re: Lenovo L560 - bios PWD

I can comfirm autopatcher is not working, and will destroy your notebook.

I have a L560, it is working. I set the SVP, read BIOS, use autopatcher patcher the bios. write patched BIOS back, and it cannot power on.
I reflash back the original BIOS, still not power on.
I am not de-soldered BIOS CHIP, using onboard flash. this method works for L380/L390/T480s etc. but it failed for L560.
NOW my L560 is dead.

because you didn't read properly your bios. this happens when you read it onboard instead desoldering. I unlocked several L560 without problem. The fact that writing back original bios dump you save it and not working should tell you that you didn't read it properly.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I have a L560 with SVP.
Here is my unpatched and my patched bios:

The Laptop Fan runs high for about 3 Seconds and then it turns itself off again with the patched bios.
I tried pulling the hard drive off and put it on again. Also tried other ram. Anyone an Idea what I could try?


Bios chip 25q128fvsq
KBC Nuvoton NPCE388NA1DX
Board LA-C421P rev 1.0

just found my S/N FC-04KEZX

I am not exactly sure if this is the right place but you people seem to have the same issue as me.
There seems to be a tool called autopatcher that can be found here https://www.badcaps.net/forum/showthread.php?t=87588
Some people claim that they successfully got rid of the SVP on a L560 in that thread but so far I have not been able to recreate that. I ordered a t48 since the ch341a is crappy even with the 3,3V mod and a whole bunch of bios chips. I hope the power will be sufficient to read the chip with a clamp, otherwise I will try thicker magnet wire and soldering.
A good tip if you attempt this: use low melt solder. You can get mechanic x for around 12 bucks from china. Makes desoldering much safer for the laptop. Just be aware that you need more flux.

I also found a few people on ebay selling chips or images of chips that are supposed to be able to unlock the L560 but somehow I think they just use the autopatcher and call it a day.

There are a few questions I am asking myself

a) is there an option to reverse engineer the actual password on the MEC/EC?
b) can I just take a MEC and bios chip from a donor board or will this get issues with things like mac adresses?
c) Is there some cheaper alternative to those svod programmers for the nuvoton chips now?

Re: Lenovo L560 - bios PWD

Dear bad caps community!

I could successfully read/write from my BIOS chip 25q128fvsq to a raspberry pi 3b+ and vice versa using a "8 pin SOIC8 Test Clip" and "6 x female to female jumper wires" (thank you "PA8600: Tech Videos and More").

Unfortunately the provided unlocked bios dumps from mcplslg123 and dr_laptop05 did not work for me. As majkel_27@o2.pl wrote the fan was speeding up and there was a dark screen after flashing the bios chip and pressing the power button.

What steps do I need to do in order to patch my original/backuped bios dump in order to get rid of the annoying supervisor password?

Since I have 3 x lenovo L560 laptops I also plan to exchange the portion of the HEX difference with the other two laptops as soon as I have a working unlocked bios dump from the first laptop.

Please help to save environmental resources...

Many thanks in advance!

Re: Lenovo L560 - bios PWD

Password in MEC.../ITE/ENE/Nuvoton Which chip have this board?

[majkel_27@o2.pl]

Re: Lenovo L560 - bios PWD

Uploaded clean Bios, clean EC, replaced TPM. There is no password but there are errors and tpm is in MFG mode. I play bios with password, TPM is normal still error 189, but asks for generating uuid, but this I can not do because bios the default is in the uefi mode, do you know where else the password can be stored?you mean Maintenance Diskette

Re: Lenovo L560 - bios PWD

Hey, I checked your bios. Unfortunately, fan, high speed and dark screen, I have a clean ec. and factory bios but unfortunately tpm remains MFG mode and error 189 uuid error. at the original bios tpm is normal, so it probably remains to read the original password from the bios file. Any ideas?
