You probably don't have a switch. You need to use the wireless application you will find in the control panel or the Fn key-special function key combo that is made for the wireless.
Hold down the FN key and then look up at the special function keys and see which one has a picture of an antenna. That combo will turn the wireless on or off.

The only way to disable it would be to disable all of the buttons. This can be done either by unplugging it from the mother board or disabling the device through device manager.

Try now~ Then you can reset your keyboard if you like

I think you have a broken USB keyboard or USB port. Simply plugging in the keyboard should be enough to make it work. First try the keyboard in a different USB port. Test the caps lock to see if the LED goes on and off. Also try a different keyboard and also test it in a different computer.

what is a device? did you mean PC, a collections of devices and chips:? a PC Is not a DEVICE it is a system.(or machine) why in the world not buy a new battery first? if charging fails. mine sometimes go bad even 1 year old, when I abuse it. and I fully expect that, if you read the battery makers pages, youd learn how that happens' (cycling the snarf out of it) if i remove the word DEVICE and add LAPTOP OR PC THE ANSWER IS THIS. IF the Pc does not run with the battery (main big) out ! the power pack is bad. the PC will run forever on AC power, a fact, !!! I do so all the time, or even the wrong AC pack used, (mixed up with other pc:) get a new pack, get one matching your systems, needs (watts) the laptops can come with 5 processor options and 4 graphic chip options, the worse mix is 100watts, HP will tell you that match. but only if YOU tell your full service tag data.... that magic, nnnnnnnABA# number tells the HP pro what is inside this laptop and what power park is right or just buy the 19v, 100watt pack. here is real HP, fixya is NOT. they can match you up as can the hp PARTS SURFER, https://h30434.www3.hp.com/
