HP All-in-one keyboard not working and caps lock light stays on

[JohnathanAyers]

I have an HP All in one desktop computer that uses a usb dongle for the mouse and keyboard. I just recently took the dongle out, forgetting it is for the keyboard as well. once I tried inserting the dongle again, the mouse connects and works, but the keyboard does not work except that the caps light is on and will not turn off. I have tried taking the batteries out for a good min and it still has the same issue. I have also tried removing the device and it still does not work. In the device menu, it states that the keyboard is working properly, however it really isn't.

It is difficult to help you if we don't know the hardware configuration of the laptop that you own.

Method #1: If the notebook will boot into Windows, you can retrieve your Product Number by pressing Fn + Esc key.

Method #2: Press the power button and immediately tap the F10 key to invoke the BIOS. In the Main section, you will find the Product number or Product ID. Post that in your next reply in your thread.

Method #3: Press the power button and immediately tap the F2 key.

Method #4: If powering on is not an option, take a look at the bottom of the laptop for the label with the product name and product number. For a desktop look at the rear for the label.

If your laptop has HP Hardware Diagnostics UEFI version 10.3.0.0, there is a System Information section that also has the Product ID.
We need that information, along with the installed Operating System information to help you.

Wireless keyboards usually have a means on the keyboard, a button, to allow pairing with the dongle.
