No input from Window side of the HDMI switch

[tarzouille]

The Envy Move do not display the video coming from it's own motherboard.
No doubt about the screen, and the HDMI switch, cause when the button is pressed. the OSD toggle from the Windows logo and HDMI.
No cable connected but the supply (battery > 70 % according to OSD).

if a HDMI source is plugged-in (e;g. Laptop) the signal is displayed.

I didn't find any post or trouble shooting dedicated to this all-in-one. All basic found everywhere are not applicable until the window input stays with "no input" status.

to trouble shoot, the Envy move has been connected to an HP usb-c dock (only screen and keyboard). No more sign of boot.

Please suggest.
Thanks you everyone by adavance

Hi @tarzouille 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for laying out the issue so clearly—and I’m really sorry your HP Envy Move isn’t displaying video from its own motherboard. 

That’s definitely frustrating, especially when the HDMI input works fine but the internal system stays stuck on “no input.”

Here’s a structured approach to help troubleshoot this:

🧩 What Might Be Happening

• Display Source Confusion: The OSD toggling between Windows and HDMI confirms the screen is functional, but the system may not be booting or sending a signal from its internal graphics.
• BIOS or Firmware Glitch: A recent update or power event could have caused the system to misroute video output or fail to initialize the internal display.
• Hardware Boot Failure: If connecting to a USB-C dock results in no boot signs, the system may be stuck in a low-power or failed POST state.

 

🛠️ Steps to Try

Perform a Hard Reset

• Disconnect all cables and peripherals.
• Press and hold the power button for 15 seconds.
• Reconnect only the power supply and try powering on again.

Try BIOS Recovery

• Press and hold Windows + B, then press and hold the Power button for 2–3 seconds.
• Release the power button but keep holding Windows + B until you hear beeps or see the BIOS recovery screen.

Boot Without Dock or HDMI

• Disconnect the USB-C dock and HDMI cable.
• Power on the system with only the battery and internal components active.
• This ensures the system isn’t trying to route video externally.

Check for POST Indicators

• Listen for fan noise, keyboard backlight, or any LED activity.
• If there’s no sign of boot, the system may need service.

You’ve done a great job narrowing things down, and I know how discouraging it is when basic troubleshooting doesn’t apply. Let’s get your Envy Move moving again 💪.
