post the original contents of the bios chip..not the update on the website..
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
you need an SPI programmerLeave a comment:

Hi everyone,
I’m working on a small technical challenge and could really use some guidance from people more experienced in BIOS/EEPROM work 🙂
I picked up a old rugged laptop (Getac S410) for $50 at a garage sale. The seller warned me it was locked with a BIOS password (prompt appears immediately at power-on, before any BIOS/UEFI access).
My end goal is to turn this machine into a dedicated automotive diagnostic PC, so I’m trying to unlock it rather than scrap it.
What I’ve done so far:
Fully disassembled the laptop

Hello,
I need help unlocking the BIOS password on my LG All-in-One 22V240.
Model: LG All-in-One 22V240
Background: I received this PC as a gift when I was a child. I left
it unused for years after upgrading to a better machine. Now I want
to give it a new life by installing Linux, but I cannot format it
because of this BIOS password lock. I have no idea who set the
password or when.
Important: The Unlock Key Hint Number changes every boot (dynamic).
Examples of hint numbers I have seen:
- Z5DD4808
- C649CBC7

Looking for some help with an Acer laptop.
Model: [Nitro ANV15-52]
SNID:55121732376
Serial Number: NHU1NAA001551350EB7600
Current BIOS Version:
After updating the BIOS, I lost access to BIOS Setup due to a Supervisor Password lock. The machine itself is completely healthy.- Windows boots normally.
- Zorin Linux boots normally.
- F12 boot menu works.
- Only BIOS Setup access is locked.
- BIOS generates a challenge/hash file.
I'm attaching the challenge file/hash below.

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...
