    X280 NM-B521 bios no display

    Hello,
    I used HP Unlock tool to remove my bios password but i think it doest work correctly.

    Step followed :

    1. Unsold the W25Q256JVEN Chip
    2. Dump memory
    3. Drag and Drop to HP_unlocker.exe
    4. I have written to memory the new file
    5. Solder the memory to the motherboard
    6. Start the computer and i will try to enter in the setup bios menu. At this moment i have loading bar "repair..."
    7. Windows startup
    8. i restart the computer and i'm trying to go again in the bios setup but the password is always set.

    Anyone can help me please ?
    Maybe it's HP Wolf security ? or a software who run a script on windows startup ?

      Use RC unlocker , don't use HP unlocker.

                          ASUS TP500LA BIOS request/repair/merge?
                          by jbonavita
                          Hi, my laptop wont boot at all
                          With original bios no POST, only LED lights
                          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                          Some issues
                          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                          B- If updated from 500LN version 203 to 300, the battery stops being recognized

                          Things I tried

                          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                          by zenius
                          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,...

                          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                          by Wahaz
                          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....

                          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
                          by Bloodhoundje
                          Hi everyone,

                          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

                          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

                          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

                          I have desoldered the bios chip (GigaDevice...
