I have Lenovo IdeaPad 310-15IAP. The upper button which is responsible for turning off the screen on the model is pretty strange. Its image is divided in two parts. I suppose it is responsible for two things, but how can I make it actually turn of the screen? Now, when I am pressing it the screen stays unaffected.
Here is the button I mean:
It is the button with F10. There are two symbols which are divided by a line. When I press the button I get the functionality of the right most button. I would like to get the functionality of the left most button.
And by the way all the other buttons work fine.
I suppose the button works fine as well, but I have to press something like Shift+F10 in order to get the desired effect (Shift+F10 does not work in the case) and I do not know what exactly I should press.
