Fix Function keys of keyboard not working in windows 10 / 11

Function keys are the 12 set of programmable keys dedicated to serve an extra purpose which regular keys don’t, which can be very useful from time to time. Nowadays, especially Laptop manufacturers are combining these 12 sets of keys and Multimedia keys in one set of keys for less space consumption. Some of the users are running into trouble because their Function Keys are not working properly.

There may be a hardware fault or sometimes it is the keyboard software bug to blame for the problem.

But before going for the fixes make sure that there is no error with the keyboard itself. You can check your keyboard with another computer. If the keyboard is working fine except the Function Keys, here are some fixes which will solve your problem-

Fix-1 Try Pressing Esc key with Fn key

Some laptop manufacturers set Esc keys as Function lock key. To get over this Just press Fn key with Esc key together.

Now, try again using any Function key

Fix-2 Try pressing Fn/F Lock /F Mode Key

This is mainly seen on the new version of the multimedia keyboards where multimedia keys are combined with the function keys and both of the operations can be accessed by a single key.  This is the cause of the error for almost every user. Follow these next steps to lock/unlock the Function keys-

  1. Hi.
    After changing my OS, Win 10, I couldn’t work with fn+f11 and f12 and f10 keys. Other combination of fn works probably.
