If it affected just one or two keys I could see it being something stuck in the keyboard. But some keys just did nothing and about 3/4th of them did shortcut functions. I couldn't scroll it kept changeing the size of the text instead. I couldn't type at all. It wouldn't let me do anything. I tried rebooting no change. I tried looking for a tool that I could change the setting on. I occasionally have to go and reset the full screen back to reg. I tried looking at the task manager to see if something was running that i could close.
I never tried unplugging it and setting it aside. I never unplugged my old keyboard they are both still connected. So I just picked up the old one and used it. I lifted this keyboard and set it on a cooler behind my moniter and there it sat. I tried it the next morning and it worked fine again. I don't understand what happened or how it reversed whatever was wrong. I had tried every key on the keyboard hopeing to reset something but nothing happened. So I wouldn't think it was anything I pushed that reset it. No clue!
