Hello,
Looks like this is one of rare places where I can ask for help about bios for HP, help will mean a lot here.
I got dax8mmb18d0 rev d
I will attach both bios here, I can't guarantee those are untouched because someone was doing something before me on both chips. Laptop was locked but working, now laptop is at my place, not turning on, just light on caps lock, charging light is normal, no screen, no boot.
Before this state guy told me that laptop was working for few days. If someone know what a problem can be, check both bios files I have read and please if someone can fix them, will be nice. I hope someone didnt make mess with bios files.
Serial number: 5CD026MZ74
Thank you in advance a lot!Comment

Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.
I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost... -
I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around 😝

Hello,
i hope to find help her in the forum. It is a littlebit tricky. I searched many Days about disabling IntelME that was may major task. So i have a Clevo PD50PNN motherboard.
At first i tried to Backup the BIOS with tools direcly from Windows(normaly i am a Linux user). But no full success because not every part of the bios was readable. So i bought a modified CH341a for a Backup.
Backup worked but since the backup the Laptop is not booting anymore. I flashed the newest Version oft the BIOS with success, verfiy everything ok.

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
