yep, there's a fn switch key somewhere that sets the input to what the fn + key is as default like the caps lock basically.
google your exact laptop model if you can't find it to switch it off, it's usually on the upper/right section and there should be a led on when it's set.
edit: sorry didn't notice the model on the first post, it looks like there's no fn lock, should be a problem with the language setting in control panel, go in and reset the inputs it should fix it.
or try the left alt+shift - usually switches between input languages
