    Lenovo IdeaPad Gaming 3 15ARH7/15ARH7D/16ARH7/16ARH7D BIOS

    If anyone needs the BIOS for this model, I will attach it.
    It is an exported BIOS image from the factory update.
    BIOS works normally.

    Thanks for providing this!
    Would this work at all for the HLG50 LA-M082P as well?
    I'm having an issue where it's not booting up and all the BIOS for it that i can find online are on forums with sketchy paywalls...

        Thank you for your quick response!

        - The full model (I believe) is:
        HLG50 LA-M082P
        Rev: 1A
        2022-01-21

        - What do you mean backup?
        - The serial number I have been searching for for an hour. The sticker on the bottom must've fallen off because it's not there, can't use any of the ways that requires it to boot obviously, and I don't have access to the original box or receipt, and I have completely removed the board and scoured everything, with the exception of pealing off the thin aluminum shielding covering most of the back as it doesn't seem to readhere well....
        The closest thing I did find that could be of use, next to the model number in smaller type on the motherboard is:

        E__:1AQ3
        HLG50 D01
        451AUG38L01
        (and then the MAC address)

                Hello everyone, this laptop has the following problem: when it tries to start the operating system, it restarts. The same happens when trying to install any operating system. It normally lets you browse when entering the BIOS. I've looked for any power consumption problems on the motherboard, but I haven't found any. Now all that's left is to test the BIOS. Any help? I appreciate it.

                  Did you see the extracted bios at post 7 .Just copy your DMI from your backup and put it into the virgin bios using the offsets 1F82000 - 1F84000

                        Hi colleague, it turned out to be a problem on the board, a fault in the PQB1 mosfet and then another fault in the MP2845AGQK controller.

                          Thanks for the answer. In my case, the problem was in a faulty DMI unit, which I transplanted into a clean dump. Flashing a clean dump without DMI solved the problem.

                              Wrong backup, that`s the NVIDIA vBios firmware. Are you sure the part number is W25Q128JV, the vBios is usually on a 2MB chip.

                                  That`s the vBios. The W25Q128JV file you posted above is the 2MB vBios written 8 times to make the file 16MB. So, someone has wriiten the 2MB vBios to the W25Q128JV chip or you chose the chip yourself (reading the W25Q16DW as W25Q128JV) in the programmer and it`s read it 8 times.

                                        UPD! In my case, the problem was not in the BIOS at all. When I soldered the BIOS chip, the processor standing next to it heated up and the laptop started. After cooling down, the defect appeared again. The problem was in the processor failure due to the black compound.

                                          Request for PW removed Bios - Lenovo IdeaPad Gaming 3 15ARH7
                                          by Chrisjacob
                                          Hello,

                                          I am writing to request your assistance to provide an edited bios without password on my Lenovo IdeaPad Gaming 3 15ARH7 laptop:

                                          Serial Number:MP2BKH42
                                          Machine Type Model:82SB0001US

                                          I am able to get into bios but not update any of the settings with password I have. So I'm assuming I need to reflash with unlocked bios. I can read bios chip withch341a programmer and get bios file off of computer. I also have updated bios file from manufacturer. Just not sure how to edit it to remove password.

                                          Appreciate any help in unlocking...
