Predator PT516-51s not find his monitor

hello, I had some problems with the built-in monitor of my Predator PT516-51s. The monitor went black and the computer stayed on. Connecting a second monitor, the second monitor worked fine. After a few days of testing and resetting/updating video card drivers, I decided to reinstall windows 11 from scratch.
Now I find myself with the black laptop screen, and in the device management, in the monitors section I find only the external monitor connected with the thunderbolt. If I show the hidden devices I find the "integrated monitor" with the words "Currently, this hardware device is not connected to the computer. (Code 45)". Does anyone know if the problem is software or hardware? Thanks

    Hi @LeoBe this is the information from Microsoft for that error, although I think it is a graphic hardware problem since the external monitor did work, in any case please wait for more answers that can provide more information to your problem:

    Paste——-
     Code 45 “Currently, this hardware device is not connected to the computer... (Code 45)”

    Full Error Message

    Currently, this hardware deviceis not connected to the computer. To fix this problem, reconnect this hardware device to the computer. (Code 45)

    Cause

    This error occurs if a device that was previously connected to the computer is no longer connected. To resolve this problem, reconnect this hardware device to the computer.

    Recommended Resolution

    No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer.

    so the only solution is to send it in for assistance?

    It would be the last option, do you currently have a warranty? but can you first put a screenshot of the device manager on the graphics card and the monitor both displayed?

    Thank you.
    All the best.

    sorry for the delay in replying. I turned on the computer after two days and it works.

    the monitor is back in the device manager.

    any idea what it could be? Some half broken connectors?

    These are the mysteries of computing :-)
    Possibly some specific power problem on the card itself, observe it in the next few days, in any case I'm glad that it's resolved at this time, thanks for sharing it.

    All the best.
