    Need Help With CH341A Programmer & BIOS Password Removal (HP Elitebook 835 G11)

    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 an EC chip. I asked a guy on Telegram (who does BIOS password removals on YouTube), and he told me I only need to work on the Main chip.

    Another thing:The HP Elitebook 835 G11 has the Q25W256JW chip and it requires a 1.8V adapter. I didn’t want to risk frying it, so I ordered the adapter and am waiting for it to arrive.

    So my questions are:
    • Is this the right approach for the HP Elitebook 835 G11 ?
    • Do I really only need to modify the Main chip?
    • Any tips or insights before I start?

    Happy to share any info I’ve gathered if it helps others too.

    Thanks in advance!

    How to add chip support to NeoProgrammer software for the CH341A Programmer
    by SMDFlea
    Adding chip support is quite easy,there`s even some instructions included with NeoProgrammer,although its not obvious where they are
    and once you do find them there`s a few crucial steps missing.

    Extract chiplist.zip to a folder,the instructions are in Import_EN.txt and in Import.xml .Its the xml file where we add the new chip.



    Open Import.xml with notepad or any other text editor.In this example i`m adding a Macronix MX77L25650F SPI_NOR chip.



    After adding the chip save the xml file and copy it to the root directory of the...

    M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
    by hotcrossedbuns999
    My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
    1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
    2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
    3. I could only locate two chips that look like bios chips. Could someone verify this

    Elitebook 840 G5 Bios Chip Soldering Question
    by Azurain
    Hi everyone,

    I have an HP Elitebook 840 G5 that I am trying to get working again. I've removed the front bios chip (the 32mb one) and have run it through HP unlocker already. I've uploaded and verified the new bin, but am now experiencing an issue that has led me to believe I've been soldering the chip back to the motherboard incorrectly.

    Essentially, after re-soldering the chip back into its place and reassembling the laptop, the charging light immediately flashes orange and white and then shifts to a solid white. The capslock and numlock lights blink seven times...
