A:Answer Sorry, I also have an HP wireless keyboard — and there is NO switch of any kind on the keyboard’s back!
The box which it came in shows something to do with the “CAPS LOCK” key, but the printing is so bad that I can’t read the rest.
I don’t use my computer that much and the batteries have lasted less than 3 months. Plus, there isn’t any polarity (+/-) markings to guide anyone when replacing the batteries.
Disappointing product!
