Logitech K360 keyboard just died on me without any sign of problem

[MS-User]

I didn't spill anything. I took care of it really good and it worked perfectly. Turned it off yesterday and turned it on today to find it won't. I changed batteries, the contacts are shiny. I don't even own this keyboard since like two months or so. The warranty is over and it just stopped working. This is my last resort, because there is nothing on the internet about this. I found a forum post 2 years ago on logitech forums...no repies of course. So I hope someone can help me draw a conclusion. Here are some things I find important:


-Keyboard was clean no problems

-It wasn't dusty outside

-My home is really dusty, because of its ruined isolation, so dust builds up really fast


Please help me
