Hi, Please help. My Logitec K270 wireless keyboard is not working. It keeps getting disconnected. I changed batteries, does not work. I see on windows driver date shows 2006 whcih does not change even if I update the driver by clicking update driver. I saw some youtube videos show to install Lotitec universal indentifier (or something like that) but this thing cannot even identify my keyboard. If I connect this keyboard 10 times then it works once for 1 hour only. WHen i pug out and then plug in the key board, the system shows error saying windows cannot identify my keyroabrd. any advice? I am using win 10. This keyboard I have been using for 3 years now. Thank you.
