Translation French → English

Hi, I have an HP Pavilion 23. When I connect it and then press the power button, the screen remains completely black. I cleaned the RAM stick and removed dust from the fan. Then I turned it on again, and the screen is still black. Please, I tried the Windows + B and Windows + V combinations, but that didn't work either.

HP Envy h8-1534: Black screen, no display output after boot

Mon, 30 Mar 2026 23:20:08 -0700

This is a longshot, but i may have bricked the system on by enabling visualization in BIOS settings than saved a state on virtualbox before force turning it off by power button after the OS froze after a auto-wake up from sleep mode

HP Z4 G4 Workstation: Gets power and fan spin. No POST

Tue, 03 Mar 2026 06:06:52 -0700

I recently acquired one of these workstations that I'm trying to get up and running. Here are the symptoms in case anyone has ideas, but I currently have it narrowed down to either the Power Supply, or the board.

Turns on when you connect power. You do not need to press the power button. It just turns on.
CPU, GPU, and PSU fans all spin. PSU will start to spin aggressively if left on for a while. (I don't remember if the memory fans spin; I took that assembly out so I could see).
No video output. Can't try onboard graphics because it has a Xeon CPU. So no iGPU.
No beep codes, blink codes, or other errors.

I would specifically like to know if the PSU is at fault (it's my current theory). Problem being. it's a proprietary power supply.

So. How do I test it? I am probably going to take the housing off and just look. But NOT TOUCH anything because I don't have a death wish. But I'm invested. And this is taking up residence in my brain.

PSU in Question. Specs/model number and weirdo connectors.

I'll probably cave and buy a new one, but I would rather be sure before I invest $$.

Stuff I have already tried. In case someone has other ideas that aren't Power Supply.

Parsing down to minimum config (Only CPU, one stick of RAM)
BIOS recovery
Installing a known good GPU
Remounting the CPU
Swapping RAM sticks around (It has 8 slots. 3 were populated. I verified they were in the correct layout and tried various sticks in the Number 1 slot.

UPDATE 04.20.2024 - Somehow this thread keeps finding people and I have still not fixed this or found a definitive answer to my question, but hopefully these voltages will help someone, or at least contribute to this discussion. I should add, I do not believe these voltages are correct.

Measured voltages on my connector when both connectors are attached to the board and power on is attempted.

Colors are constent with typical markings

Orange = 3.3V
Red = 5V
Yellow = 12V
Black = Ground or Voltage measured
Purple = 1V (I am not convinced this is normal, but nevertheless have nothing specific to compare to).

Even though my device powers on almost immediately after the PSU is connected to power, I can power off. Voltages with the power off.

Anything not marked has no voltage and all previously 12V lines have very nominal voltage (~.08V).

I am again starting to think the PSU is to blame. I have checked the board pretty thoroughly previously for shorts, but since it is a rather large board, this is somewhat difficult.
