Lenovo ThinkPad T470 bios password decrypt

[Robi50]

Original BIOS was good but had a password on it, problem was that it didn't even give me a chance to save the original BIOS, it died after a few tries of trying to read the BIOS, did you hear about this from other people, I think I read that someone had the same symptoms but that was because a component was knocked off and I didn't see anything like that on my board.

When i was trying to read my Bios from my T470 so I can use the Autopatcher, something must have happened becasue now the laptop, only blinks the power light once and fan spins up, but no reaction to the power button, try to erase the chip and reflash with all kind of Bios from here but no change, How screwed I am and is this even a BIOs problem, Bios chip is not dead cause I can flash and erase it, but the laptop has not much life in it, checked if any componenet was knocked off, but I didn't see anything, also checked the legs of the chip and they do have solid connection.

Any help would be appreciated.

Thank you.

Now your computer is really dead because you didn't keep a backup of the original bios (even though they were corrupted).

Hello,

I have this T470p and it requires a password to enter BIOS.
Dumped the BIOS, used autopatcher, but the laptop is playing a melody and nothing happens.
Tried autopatcher a second time and the screen stays black, without any sound.
Can someone help and maybe remove the password?

Thread merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

Hello.
I have Lenovo T470. It has supervisor password and I couldn't remove it by myself.
I was able to dump the original BIOS image and patch it with Lenovo autopatch, but got a black screen after flashing it.
Could anyone help me remove the password from the BIOS please?

Thanks everyone. I figured it out myself. It is necessary to block the switch of the lower cover

Hello Eveyone Please i need help to unlock Thinkpad T470.
I have tried The AutoPatcher but i get melody tone without display
and i tried extract bios region from a patched bios but no luck no display

So you visited the following link:
https://www.badcaps.net/forum/showpo...52&postcount=1

1)And got python downloaded and installed first?

2)Downloaded the autopatcher zip?
https://www.badcaps.net/forum/attach...2&d=1597843816

3)Unzipped the files and opened a command prompt (type "cmd" without the quotes in the address bar of the explorer windows showing the unzip files and hit "enter")

4)Copied your BIOS rom/bin file to the folder and typed:
autopatch <your_bios_image.ext>

5)looked for an output file similar to:
your_bios_image_PATCHED.ext

Let me know where you are stuck in that. If you got that far make sure you follow step 1-9 after that bearing in mind the NOTES section if you have trouble

Good luck!
