I just turned my laptop back on and my mouse and keyboard connected via wireless usb

The mouse works fine but the taststur is not at all the first few minutes it has funtioniert and then no longer my operating system is windows 10

So

Check the USB connection, disconnect the distributor from the mains or PC compl., Plug possibly the USB cable into another slot. Jo

I've tried everything but it still does not work

Maybe the battery is empty from the keyboard?

So

Replace the keyboard and thus check the USB connection, let go of your possibility - problem detection, the PC itself check what is broken, Jo
