        HP Probook 640 G5 i5 8th gen Touch screen - Bios Corrupt

        Good day all, Yesterday i tried to create a dump of my bios so i can try to delete admin password. I noticed after every read i got a corrupt dump. (was trying out a new wson8 test lead adaptor). Now the laptop only has a flashing caps lock and no signs of life. Very possible this new test lead caused the issue.
        How can i go about rebuilding a compatible bios for the laptop?

          If youve got corrupt reads you`ll have corrupt writes.Solder wires to the pads instead or desolder the chip,solder to an adapter board or use one of those adapter boards that has a lid that locks down, and hope it can be read.You might have corrupted the bios data or damaged the chip.

            Yes i have ordered a adaptor board and hoping for the best, but with my luck i might as well order a new chip and try to build a bios for it.

                        Hello, I have HP ProBook 640 G5.
                        It suddenly went off while doing a BIOS Update, right now it power on but with no display at all, I have downloaded some bios from internet and it now boot up and show BIOS Update and then the same thing happens.
                        I have included the original bios dump.
                        16 & 32 bit files.
