Windows 10: fn+F7 and F9 not working

I had not used these keys for a long time! Today, when I tried to disable the laptop touchpad, I realized that this key does not work! On the other hand, when I tried to turn off the screen, I realized that even that one key did not work! Of course, the other keys work well and have no problems! Even airplane mode and sleep mode keys, which I never use, work well! But only the two keys I mentioned above do not work! Since only these two keys do not work, do you think the problem is with my laptop ie there is a hardware problem or not! Problems with software or Windows?


Another problem is that sometimes the CPU stops at a certain percentage and the laptop gets stuck or hangs! The interesting thing is that when I play music, a certain sound is heard from the speakers in the form of a bazaar or a sharp and deadly sound! In other words, the system slows down and a certain sound is heard from the speaker when the music is playing. I do not know where the problem comes from, but it only goes to this state for a few seconds, about 5 seconds on the CPU. I really do not know why and I do not even know what to call it! In the photo below, I show an example so that you understand what I mean!

fn+f5 and fn+f7 stoped working

After I reformated my Asus keybord short cut's fn+f9 and fn+f7 stopped working, I defined through smart gesture that the touch pad gets turned off when I plug in a mouse, but the short cut stiil doesn't work, and I haven't found any solution for fn+F7

 

F7, F8, F9 keys do no longer function correctly

Hi MET_02

I am Dave, an Independent Advisor, I will help you with this . . .

If pressing the function key (F7- F9) does not work on its own, if you press the Fn key + F7, or F8 or F9 does that produce the requited action?

If so, boot your laptop into BIOS and in there look for a Media Keys/Function keys setting and toggle that setting

Or. f your press the Fn key +Esc key, does that toggle the need for the Fn key to be pressed?

 

F7, F9 and F10 aren't working!

I have a problem. My keys F7, F9 and F10 stopped working. I can't control my microphone from F7, can't control my WI-FI from F9 and can't open PC Manager from F10. Any ideeas what can I do with them?
