Hi everyone, I hope you're doing well.
I'm running into an issue with a Lenovo motherboard.
It has a BIOS password; I replaced the physical BIOS chip and even reprogrammed it, but the password remained.
Upon further research, I discovered that the password isn't stored on the BIOS chip itself but rather in the EC (Embedded Controller).
I tried applying a patch to the .BIN file using Lenovo Autopatcher, but the tool failed to do it.
I also attempted to edit the code using HxD and UEFITool.
Despite my best efforts, I couldn't...

Hi everyone,
I'm trying to unlock the BIOS admin password on a Dell Latitude 3420 (regulatory model P144G001).
Service Tag: 5727KG3
Lock code: ends in 8FC8
Chip: Winbond W25Q256JV, 32MB, WSON8 package
BIOS version: 1.15.1
I have a verified backup of the BIOS chip (confirmed with matching checksums across multiple reads).
Could someone help me identify/patch the password block, or point me to a clean reference dump for this exact model/BIOS version?
Thanks in advance!...Last edited by ale1234; 08-07-2026, 04:57 PM.Leave a comment:

Hi,
my laptop is stuck in a BIOS password loop after I attempted to clear the password (I nulled it) in the BIOS settings. It now freezes after 3 failed password attempts.
I tried to do a clear CMOS, but there is no visible battery. I sent it in for repair, but it didn't work out. I finally decided to dump the BIOS myself using a CH341A programmer.
Could someone please help clear the password/NVRAM region from my dump?

Forgot my Galaxy Book 3 NP750QFG-KS2BR BIOS Password!
Hello guys!
I just thought that would be more safe to have a BIOS password in my Samsung Galaxy Book 3 360 NP750QFG-KS2BR in case it is stolen.
I sware that I saved the password in my PasswordSafe app to organize passwords but I didn't and now I can't access the bios. The notebook works normal but I want to do a clean install of windows, that Samsung's version is messy and with a lot of bugs that are stressing.
Is there any people who can access the Samsung's generator program ou could give me some hope? They are charging me and asking me to drive over 300 hundred kilometers... -
Where to locate EEPROM BIOS Chip for ThinkPad X1 Carbon 6th 20KH002SUS
Hello, I bought X1 carbon 6th from Ebay somehow the laptop is bios locked and I don't know the password and heard that you can short the chip to get through the bios password. Where is the EEPROM chip located, some may say it's underneath the motherboard or above.Last edited by THinkpadIsTheGoat5456; 12-21-2025, 11:58 AM. Reason: edit: I didn't want to buy SPI Programmer and so I'm wondering if I could bypass using the short method. -
Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
