    Help please HP Zbook 15 G3

    I was trying to remove a bios password, I removed these chips and read the data from them and unlocked them via the awesome tool on the forum but upon soldering them back now my darn laptop wont switch on and the power button flashes and also the charging port is illuminated

    I likely messed something up, am using a tl866 programmer, also could anyone be so kind as to show an image of bios chip orentation for this model incase I made a booboo

    Kind Regards

    Paul

      Appreciate that, I've also tried that to no avail, is it possible my reads were bad.

      Would it be ok to flash a bios from the net as I have possibly contaminated the bios.

      Thanks for your time peste

                      No start/image was fine leading up to desoldering and reading of bios. Also very well soldered back

                        I need to unlock the BIOS password on my laptop, an HP ZBook 17 G5, I don't know if there is any method.
                        by kevin_23
                        Good morning and delighted to be part of this community, I have purchased an old business laptop, a HP ZBook 17 G5 system model with the Intel(R) Xeon(R) E-2176M CPU @ 2.70GHz, 2712 Mhz, 6 main processors, 12 logical processors, BIOS version and date HP Q70 BIOS version and date Ver. 01.29.01, 09/24/2024 SMBIOS version 3.1, the BIOS is password locked, I cannot access the BIOS to change parameters, my question is if in this model the BIOS can be unlocked without having to open the laptop or on the contrary, do you have to solder or something? Thank you very much

                        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....
