Mr.
I was using a Logitech Wireless keyboard Y-RAY81 for a couple of years with no problems until a few days ago. I had the keyboard charged for 24 hours (showing a green light and stable), yet none of the keys are functioning. I have tried the online suggestions provided by Logitech but to no avail. Please help (Email: rtkh_88@yahoo.com.sg). Thank you very much.
