HP Envy Curved All-In-One 34 - Keyboard and mouse don't work after using as monitor

[Drake42]

I'm able to use the CTRL-SHIFT-S-D key combo to switch my all-in-one computer into being a monitor for an external machine, but when I switch back the keyboard and mouse are no longer working for my computer and I have to reboot or logout and login again.  CTRL-ALT-DEL works, but that's it - volume keys aren't working, the mouse doesn't work, etc.  Oddly, if I go to a login screen, the mouse and keyboard do work there, but not within Windows.

Super annoying.  This just started recently, so I assume it's due to some recent update, either to Windows, to some driver, to the BIOS, or to the HP Display Control app.

Hey there! @Drake42, Thanks for stopping by the HP Support Community!

I understand you have wireless keyboard and mouse issues with the PC.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Have you tried checking with a different set of batteries?

Have you tried checking with a different keyboard? Does the issue persist?

Have you tried connecting the USB receiver to different USB ports on the PC?

Please share the product number of the PC to assist you better.

Excellent description and a great diagnosis done. It is greatly appreciated.

Try updating the BIOS and chipset drivers on the PC and check if it helps.

You can update the drivers on your PC using the HP support assistant.

Try few steps recommended below.

Restart the computer.
In Device Manager, uninstall and reinstall the keyboard software:
In Windows, search for and open Device Manager.
Click View and select Show Hidden Devices.
Click the arrow next to Keyboards, right-click the keyboard device name, then select Uninstall to remove the device from Windows.
Continue removing device names in the Keyboards category until all device names have been uninstalled.
Restart the notebook. Right-click Start (), select Shut down or sign out, then select Restart.
Wait for the computer to restart and open Windows.

Also, Re-synchronizing the keyboard and/or mouse causes the devices to reconnect to the receiver using new identification numbers.
   NOTE:
You must complete the following connection sequence within 60 seconds. If you do not complete the sequence in 60 seconds, start over.
Disconnect the wireless receiver from the USB slot.
   NOTE:
For some HP All-in-One and desktop PC products, the USB receiver is built into the computer. Check the service manual for USB wireless receiver removal process.
Wait 10 seconds and push the receiver back into place, making sure to push it in as far as it will go. If the receiver has an LED indicator, the activity light on the receiver comes on and then goes off within five seconds.
   NOTE:
If problems persist after resetting AND you have another wireless keyboard or mouse nearby, perform these steps again, holding down the keyboard or mouse sync button for ten seconds. Doing this might give the keyboard or mouse a new ID number in case the other keyboard or mouse was using the same number.

Wireless keyboard or mouse does not work or is not detected

● Be sure that you are using the wireless keyboard or wireless mouse within range of the transceiver, approximately 10 meters (32 feet) for normal use, and within 30 cm (12 inches) during initial setup or for resynchronization. ● Be sure that the mouse is not in Suspend mode, which occurs after 20 minutes of inactivity. Click the left mouse button to reactivate the mouse. ● Replace the batteries in the keyboard and/or mouse.

Nope, it's none of that.  This is the keyboard that came with the computer, the OS, drivers and BIOS have all been updated, and it only happens when I use the all-in-one as an external monitor and then switch back.

This never happened before - it only started a few weeks ago.  I think one of your updates - or maybe a Windows update - screwed up your Envy all-in-one computers.

I have no intention of performing a system restore and then spending hours re-installing a slew of Windows security patches, driver updates, Windows updates and other detritius...only to end up in exactly the same place.  You guys need to make sure your hardware continues to function with the curent version of Windows.  This includes the patches and updates delivered via your own HP Support Assistant app, which might also be responsible for the issue.

@Drake42,

When you perform a system restore you don't have to reinstall any software.

System restore adjusts the settings back to the date when your computer was working fine.

Also, to isolate if it a hardware or a software issue you need to perform a system reset on the PC.

If you don't like performing either options suggested. Please contact HP support so they can take remote of the PC and assist you further with the issue.
