    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

      use the program only for the 16MB bios ... the other two remain the same ..

          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

                                              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...

                                              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,...

                                              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....

                                              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...
