          Unfortunately not. When I press the power button, the orange light lights up very briefly and nothing else happens. Is it possible to solder in another BIOS chip?

            Can I install this chip W25Q256JVEQ Flash IC or does it have to be exactly the W25Q256JVEN that is installed?

                        Hi, thanks for the file. With the new file flashed, I'm getting no power on the laptop and only an amber light when the button is held. I double checked the orientation of the SPI flash chip when resoldering it.

                        I only see 4 bytes of difference between the original and new files. Is that expected for this model?

                        Thanks!

                          check well the soldering bin that the hardware friend gave you is correct, check if you blew any resistor or capacitor near the bios... if you are not sure upload an image of the bios chip and its surrounding components

                            Got it. Turns out I didn't have the wson-8 SPI chip aligned quite right. I removed and resoldered the IC on, and now the laptop is functioning great!

                            Thanks for the help!

                                    It's the same file.
                                    Which programmer do you use? Are you using a clip or de-soldering the Chip?

                                          my chip is - 25Q256JVEN

                                          and my programmer have only that option - reading all same.
                                          see picture
