Re: Lenovo t460p bios password unlock
After the bios reprograming the laptop doesnt boot only when i press power button makes a sequence like:
1- press power button
2- Laptop start keyboard light and light of the power button 1 sec
3- turn off himself with out pressing the power button
4- turn on again himself with the keyboard light and power button light again but no video and fan stops after 5 sec.
You will surely wonder if it worked and you could access the bios because you reprogrammed it again?
Basically...

Re: Lenovo t460p bios password unlock
Also i talked with another guy that have some experience about this issues and say this about the Supervisor password. Also for the ECROM reprograming he say it i can do it without desoldering the chip. It is programmed without removing it from the motherboard, by means of a special SVOD or JTAG programming device, by connecting it to the motherboard via the keyboard port on the motherboard
[I][B]All administrative type passwords, their encryption keys, for ''ThinPad'' series computers are stored and backed up,...Leave a comment:

Re: Lenovo t460p bios password unlock
What did you do to recover it, did you look for someone who had the same bios without a password but with a clean ME?...Leave a comment:

Re: Lenovo t460p bios password unlock
Seriously? I didn't know, it may be that when reading with the programmer something happened since I did it with the soic clip.
What can I do now since I don't have any copy of that bios.
because I downloaded the uefitool and i checked all copies i did before the write and all the copies I made are just as corrupt...Leave a comment:

Re: Lenovo t460p bios password unlock
No, all the components are in their place, always when desoldering a component such as a chip, I protect the area where I am going to solder with electrical tape. i have photos of the chip
update: old bios when i put on the motherboard It sounded an error message of 5 beeps, pause, 5 beeps...Last edited by 50jaker; 01-04-2023, 12:22 PM.Leave a comment:

Re: Lenovo t460p bios password unlock
I have tried again and nothing, and the chip is fine since I have unsoldered it and it reads the data correctly and writes it well, the only bios that at least reacts is the original one and it gives me 5 beeps as if the motherboard were dead but Actually, the video worked perfectly and it started with the locked bios, but now that I have tried to go back to the locked bios, when i turn it on it only gives me 5 beeps.

Re: HP BIOS unlock tool
Hi @RethoricalCheese, I have a question, I have an HP Probook 6470b but it has two users in the bios locked by password, I only know the password of one them, but unfortunately the Bios Administrator I have no idea... I bought it in that state 5 years ago, I would like to know if in this state your tool can unlock the bios administrator but having an extra user in the bios.Leave a comment:
