Wireless keyboard suddenly not working

[72hours]

My wireless keyboard all the sudden isn’t working. I have changed batteries and still not working. Checked  Bluetooth & other devices. The keyboard doesn’t appear to be there. And tried Add Bluetooth or other device, and the keyboard doesn’t appear to be on the list. It’s an all in one computer. Thanks

@72hours -- if you cannot "pair" that BlueTooth keyboard with some other BlueTooth-enabled computer, then it is time to send the keyboard to an "end-of-life" electronics recycling centre, and purchase a new BlueTooth-capable keyboard.

hi

that probably won't change much, but it's probably not, a Bluetooth keyboard / mouse kit
That one or the other no longer works, ok, but both at the same time, it is more rare

see if you find a USB dongle receiver, I do not find for this model, but for another it is inside

It would be necessary to be able to test both with another computer,
Either the dongle is broken or it is another problem, and in this case it may not be necessary to change everything.
