        bios extracted from the HP site update ... this model has two versions of the bios, yours is 08007 ..

            Try AsProgrammer software,it works better with winbond chips.The CH341A software will often say its verified even when it hasnt written anything.If the virgin bios posted by @peste isn`t working then the problem is somewhere else.

                  When you use a virgin bios it will have no DMI info,serial number etc. To fix that use HP DMI tools ,BCU (bios config utility) and/or wndmifit/nbdmifit .

                        The bios backup is corrupt.Maybe the bios chip is dying. Try another bios chip,and the virgin bios.If it doesn`t boot with a new chip and the virgin bios its not a bios problem.

                              replaced the bios chip programmed with the virgin file 08007, it turns on recognizes the ram in fact it turns off after a second that I pressed the on / off button, but nothing is seen on the external screen, I remind you that the internal one is not there because it had the connector burned and I had to unsolder it, usually by connecting the external monitor you can see it even without the operating system installed, but in this case no, what can this depend on some hardware problem or some keyboard setting?

                                    Try this EC,extracted from the 08007 virgin bios posted by @peste .

                                      this is identical to the file that is present on the chip, after reading it I have compared them and they are identical
