@unick
What type of password do this ThinkPad have? There are 3 types: Power-On Password, Supervisor Password and Hard-Drive Password. Maybe is the hard drive that is locked (CYLINDER+LOCK) and needs to be replaced.Comment

Re: Remove_SMM... UEFI.
Power-On password is stored in CMOS volatile memory, meaning that in order to clear it all you have to do is to remove/disconnect all sources of energy for 1-2 minutes (main battery, internal battery, CMOS battery, ac adapter), then reconnect.
The procedure/patched files in this thread are specific to clear Supervisor Password and to deactivate CompuTrace.Comment

Re: Remove_SMM... UEFI.
Tried unlocking T14 through JTAG and was successful in reading MEC1663 .. but
serial numbers were nowhere to be found in the dump, but they were in the bios instead. I blanked the MEC and waited in the hope that the Bios will rewrite it but nothing happened. So I wrote a clean dump into the chip and booted the Thinkpad (holding my breath..) and was greeted with a Supervisor password prompt..(WTF??!!) SO I said to myself perhaps the pass is in the Bios , since it's the first time I've seen serial numbers in the Bios.. I wrote back Clean firmware from Lenovo website and still.. password prompt!!.. SO that leaves to believe the password is now stored elsewhere.. perhaps in the TPM chip?(ST33HTPH2E32) since that chip also has flash memory.. For those who want JTAG_RST# location, I've posted it below.. hope we all put our heads together to come up with a solution..

@siddiq
After you have READ, ERASED and PROGRAMMED EC/KBC seems as the Supervisor Password is still set (most likely still in EC/KBC RAM), so try disconnecting all source of energy for 2-3 minutes, reconnect and try again. You will then need to program laptop DMI like serial number, model number, etc. using Lenovo EFI utility.Comment

Hey everyone!
I need help with my Lenovo Chromebook 100e Gen 3.
Here are the details:- Motherboard: LA-L131P
- MFG Date: 2022/01/07
- MTM: 82J80001BR
- MO: MPNXB2103001
- Factory ID: LI123
I bought a new Winbond 25Q128FVSG chip.
The chip currently on the board is the same model but with different ending letters.
I can’t use the CH341 clip on the chip that’s on the board because it’s too low-profile and doesn’t make proper contact.
The Chromebook is Google account locked, and I’ve already tried everything.
I understand that I need to replace or... -
Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.
For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent... -
Its a bit of a long tale but i swapped the original hd for a 2tb ssd,i want about 6 bootable partitions,it needs the uefi enabling in the bios,I am ok with that,the issue is i cant convert the drive to gpt when it has data on it,the issue is windows wont install to a gpt drive,there is a utility from hp to install the efi partition on the drive but it runs on windows,its a chicken and egg thing,can anyone explaine how hp did this?,I am pulling my hair out;it seems i need to run the hp uefi tool to make the uefi option work in the bios, but it needs windows to run this that wont install on a gpt...07-15-2024, 10:15 AM -
Hey guys,
Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.
Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?
From what I've... -
Hi guys.
I am very new to this business and i have some questions. Maybe someone can help me further.
I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!
