    HP G3 BIOS

    Hi Peeps.

    Quick question. Might sound silly so bear with me pls.

    After flashing a BIOS with a flashing tool, my laptop went from stone dead, to the fan spinning. However the screen doesnt show POST. Is there anything like pulling out the battery AFTER flashing the BIOS one needs to do or is there another issue I am sitting with now?

    Did the laptop work before the bios was reflashed? If yes, apply the original bios or a known good bios image back onto the bios chip. If you require a known good bios, make that request inside the dedicated bios forum.

      Which battery you are talking about-CMOS Cell or backup battery?
      CMOS cell should be always removed before flashing bios.
      Are you sure the new bios is 100% working and me cleaned?

        Ah. Did not know bios battery needed to be removed. I am speaking about the CMOS battery.
        Presume the bin file from manufacturers website is ok to flash?
        Flashed that, and orange charge light blinks. No power.
        Flash a BIOS from https://www.badcaps.net/forum/troubl...probook-450-g3 and the fan spins at high rev with nothing on the screen.
        HDMI also shows no pic. external keyboard shows no power.

          Use the bios from badcaps for the time being and measure voltages on all the coils.
          Link schematic,if its posted on badcaps forum.

            X270 - Bios flashing help
            by Timeeez
            Hello everyone,

            I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.

            Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?

            [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....

            Flashing ASUS UX51VZ with correct bios
            by Flyview
            Hi!

            Happy to be part of this forum for my first post!

            Short story:
            I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.

            1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?
