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...

Hi,

I have a problem with the BIOS password on the Fujitsu Celsius R920 mentioned in the title. The method using the Fujitsu BIOS Unlocker does not work, and there are no jumpers on the motherboard either. Below is the dump.
Please let me know how to remove the password by modifying the BIOS, or send me an unlocked BIOS dump and I will adjust it myself....

Hi Guys,

Unfortunately, I put a password when I bought the laptop to protect the BIOS, and I can no longer remember it.

If I could get some assistance to unlock the BIOS, I would be very grateful.

Is there a more budgety programmer that works well, and would I have to desolder the EC?
Any help is greatly appreciated, thanks!

So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the...

Hey everyone,

I recently bought a CH341A programmer, but I’m still not 100% sure what to do next. I couldn’t find any tutorials specifically for the HP Elitebook 835 G11, so I’m trying to piece things together.

From what I’ve learned so far, the process looks something like this:

1. Use the programmer to read the chip.
2. Save a backup of the dump.
3. Open the .bin file in Hex Workshop.
4. Replace certain lines with “FF”.
5. Write the modified file back to the chip.
6. Boot the laptop → password should be gone.

I’ve also heard that some systems have both a Main chip and...

Hello,
I hope I'm in the right place to make my request. Now that I've made my presentation, I'd like to make a request regarding a 2017 HP Spectre PRO 13 G1 laptop. I have a lost BIOS password. I really don't remember setting a password on this computer, and after changing the battery, the computer no longer wants to boot without it. Can you help me remove the password?
I read on the forum that someone who had a model similar to mine managed to remove the password, so I figured with any luck I'd find some help here.
