Good morning, the pc only turns on the front led and the fans but not from acoustic signals or other. I have already tried to change the video card to the RAM and the CPU but nothing. Could it be the bios?

Re: Help HP Z440 workstation
Yes, that's what I mean. Move the BIOS reset jumper. Make sure you move it back afterwards.
Can you get the BIOS from HP? Typically they don't go bad by themselves though..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Help HP Z440 workstation
My hp z400 beeps if it doesn't post.
If the power button it's blue the it passes the cpu ram then GPU
If there is no display with blue power button the it's GPU.
That series it's heretic with beep sounds if something it's wrong.Just cook it! It's already broken.

Not sure if the power supply is standard...
the last time I had worked with Z400 ... PSU pin layout is a little different.

Re: Help HP Z440 workstation
Sorry for posting in an old thread, but I was trying to fix this computer and flashed "Z440 PRD_EXT_ME M60_0247.zip" by @SMDFlea. With this bios motherboard shows no post codes (and it was showing some of them with original bios), so this bios file isn't working. I built one myself using update from hp support and clean me region. After flasing this bios system booted ok.Attached Files
