                                      HP 640 G2 Bios Request

                                      Hi Guys,

                                      I have a machine a customer brought in, HP 640 G2 with a corrupt bios.

                                      Mobo model number is circus-6050a2723701-mb-a02

                                      The machine was working fine and they did a bios update, screen went black and nothing else after that.

                                      caps lock blinks 5 times and fan runs at high speed.

                                      They did make a backup of the bios before starting the upgrade, but no auto recovery method seems to work.

                                      In the folder of the recovery bios, there is 3 files.

                                      The 0151 zip file contains 2 bios files N76 and N87, with date modified 2020/10/23

                                      The N76_0147 zip file contains N76 bios file, modified date on this one is the date of the failed bios update.

                                      The files are 9 216kb, the bios should be 16mb.

                                      I have already tried a few bios files without any luck.

                                      Can anyone please rebuild the bios ?
