17-cp0700dx backlit black screen

[Ventureq]

Hi, after choosing a firmware update from windows 11 update the screen is black(light glos). Only the On/Off-light is on and the fan is running, that's it. I try all recovery procedures i found in the internet: <windows><c>, <windows><v>  <windows B> and recover from usb-drive ... no success.  If anyone has an idea what i can do, please tell me. I don't want to send it to HP; there must be a quicker solution.

@Ventureq, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like you're dealing with a serious issue where your HP laptop's screen remains black after a firmware update, and traditional recovery steps haven't worked. There are a few possible solutions you can try to resolve the issue. Since you've already attempted basic recovery methods, let's dive into some more steps to troubleshoot:

Hard Reset

Performing a hard reset can help clear any residual power issues that might be preventing your laptop from functioning correctly.

Power off your laptop.

Disconnect all peripherals (USB devices, external monitors, etc.).

Unplug the power adapter.

Remove the battery (if it’s removable).

Press and hold the power button for 15-20 seconds to discharge any residual power.

Reconnect the battery (if removable), plug the power adapter back in, and try turning it on again.

Use HP's BIOS Recovery (if available)

Some HP laptops have a built-in BIOS recovery feature that might be able to restore functionality. You may refer to this guide: HP Notebook PCs - Recovering the BIOS (Basic Input Output System) | HP® Support

Perform a System Recovery via HP Recovery Manager

If you’re able to get some screen activity or access the BIOS or recovery options, try performing a system recovery.

Power off your laptop.

Press the F11 key while turning on the laptop.

This should bring you to the HP Recovery Manager screen.

Select Troubleshoot > Reset this PC or System Recovery.

If you can access these options, you’ll be given the choice to either reset your PC or restore from a backup (if available).

Try an External Monitor

Since the issue might be with the screen or GPU, try connecting your laptop to an external monitor or TV:

Use the appropriate video output port (HDMI, VGA, etc.) and connect the laptop to an external display.

Check if you can see the Windows recovery screen or if there’s any sign of life on the external monitor.

Perform System Restore (If accessible)

If you have the option to access the recovery menu via the steps above (e.g., F11) or from an external display, try restoring the system to a point before the firmware update:

Go to Troubleshoot > Advanced Options > System Restore.

Select a restore point that was created before the firmware update and proceed with the restoration.

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

Take care and have a good day.

Well I had done all of these, but in good faith did them again. 

I was able to do a BIOS recovery from USB. I need to double check, but I think one of the USB ports might not work, as I used a different port this time and was able to recover, even doing recover Bitlocker which was the default format of the SSD. Not a fan of Bitlocker, but this was my dad's computer. So I am recovering. 

Thanks for the help.

Hi @Ventureq,

Thank you for your response

I’m really glad to hear you were able to get the system to recover using a different USB port. Once the recovery fully completes, please let me know how everything turns out — I’ll be here if you need any further assistance.

Thanks for sharing your experience — it sounds really frustrating to deal with persistent display issues. Getting a repair ticket is a smart move, especially if it's a recurring problem that affects usability. In the meantime, you could try updating the graphics drivers and checking the internal cable connections, just in case. If that doesn’t help,  mesolyft.com sticking with the support route is the right call to ensure a solid long-term fix.
