THE BIOS COMPANION BY PHIL CROUCHER

Go BIOS and check if the FN key be disabled.

You're talking about My PC and device manager and I'm talking about Bios.
The BIOS (stands for Basic Input/Output System) is system software inside your computer that helps the computer start up, even before Windows does. It also contains key settings about what the computer has on board.
In newer computers, it exists on a special chip called CMOS (stands for Complementary Metal Oxide Semiconductor).

You can go into the BIOS to edit or change the technical information about key components of the computer like disk drives, keyboards, and display settings. It also keeps track of the date and time.
The BIOS can normally be accessed when you start your computer. You may see a reference to "Setup" when you turn your computer on. That’s your opportunity to get into the BIOS. It usually requires the push of a function key, such as F10, to get access to it. That "F" key varies between computers. Sometimes it’s not even one of the Function keys, but the ESC key or DEL key.

If a logo screen—like HP or Dell—is displayed during the start up process instead, then you may want to check with your computer maker for a command to turn off that screen and display the start up information, which is listed when a computer is powered on.
A partial list of BIOS access commands by brand is listed at the end of this article.
The BIOS also contains the boot-up sequence. Normally, computers are configured to boot from a hard drive.


Before you do anything to your BIOS, it’s always a good idea to record the original settings on a sheet of paper that can be kept in a safe place so you can reference it later if you need to reset it.
Here is a list of key sequences for various brand-name computers. If yours is not there, check with your manufacturer or watch for info flashed on-screen when your computer first starts, before Windows begins. It may say

"For setup hit..." That will be how to get into the BIOS on your machine.
