does not work, turns on, turns the fan mo does not see the ram and the screen is black, with the other bios it did everything except that there was no video signal output, I state that there is no display, I tried only with monitor external

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.

Re: hp 350 G2 bios

is there any operation to do after loading the new bios?

Re: hp 350 G2 bios

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 .

Re: hp 350 G2 bios

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.

Re: hp 350 G2 bios

for the moment I suspend waiting for the new chip

Re: hp 350 G2 bios

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?
