Son killed his HP Pavilion by pressing Windows key + B

[Kimber2020]

My son (11yo) decided to run some key combination he found online and has basically rendered his pc useless.

He says he held down the Windows key + b key and the screen went blank with error message saying no signal. He and his dad have tried troubleshooting the cords and all work fine as well as the monitor. Does anyone know what he’s done and how to undo it? We’re at a loss.

Yes we’ve tried the steps as listed in that post with no success. It appears the keyboard isn’t functioning properly either now so I’m not sure if it’s being recognized by the pc

@Kimber2020,

If you have a wireless keyboard/mouse combo, move its transceiver dongle to a different USB port.  If you have a wired keyboard, move its USB cord to a different USB port, and see if that makes a difference.  Also, if you have a wireless keyboard, make sure that its battery/batteries is/are not dead.

None of the ports appear to be working since we’ve tried moving the keyboard to all available ports with no luck. We’ve also tried using a different keyboard entirely. None of the keyboards are functional when plugged into any port on the pc

@Kimber2020,

Since the warranty of your HP Pavilion Gaming Desktop TG01-2170m CTO has likely (just) expired (please verify), if this was my PC, I would try a CMOS reset first, as shown here: Replace the Restore CMOS to Factory Settings | HP Slim Desktop S01-aF0000, S01-aD0000 | HP - YouTube.

Yes the warranty just ended two months ago making this extra frustrating. How is it possible to brick a computer using two keys? I will definitely not purchase another HP if the quality of the product is this poor - lesson learned.

The keyboard is non functional however other peripheral devices worked when plugged into the same port (light up mouse pad works). Why could that be happening? We can’t try any of the recovery key combinations since the keyboard is not recognized. Is there any work around there before we try resetting the battery on the motherboard?

@Kimber2020,

I'm afraid not: you used the term "bricked", and that was exactly what I was afraid of had happened.
