How to Install Lenovo Slim Usb Keyboard (SK-8821) F1-F12 Keys on Windows 10

Question

I have Windows 10 Pro x64 and installed on Lenovo V520 MT-M 10NK
And i also have the Lenovo Slim Usb Keyboard (Model: SK-8821) that comes with it.

When I press the buttons F1,F2,F3 and so, I got nothing.
If I press the Fn+F1 buttons the F Keys are working.

How do I change the F Keys to work immediately without pressing the Fn Key together?

Also, where can I find the correct Software/Driver for this?

I try searching the web and the Lenovo support center but not got any solution for Windows 10. It works only on windows 7/8/8.1

Answer 1

You actually don't have F1, F2, F3 keys. Those are Mute, Quieter, Louder keys.

See USB HID Keyboard Scan codes -

#define KEY_MEDIA_VOLUMEUP 0xed  
#define KEY_MEDIA_VOLUMEDOWN 0xee  
#define KEY_MEDIA_MUTE 0xef

To change the meaning of those keys, you must install a suitable driver.

Windows 8.1 drivers sometimes work on Windows 10.

You may be able to do some remapping using some other generic driver or keyboard/scancode remapping tool.

Answer 2

For me it worked to download the Windows 8 driver, extract it and then run the "Lenovo Slim USB Keyboard" tool from where the driver was extracted. No remapping tool required.

1. Download the drivers from the Lenovo drivers page (or search for "Lenovo slim USB Keyboard driver")
2. Extract the driver (usually to "C:\SWTOOLS\DRIVERS")
3. run "Lenovo Slim USB Keyboard.exe" in C:\SWTOOLS\DRIVERS\KEYBOARD\c6kyb05us17\x64
4. There you can tick a checkbox for using the FN keys primarily

Hope that works!

Answer 3

Here's a solution that works cross-platform, and does not require installing any unwanted software:

Simply fold a piece of paper 4 times, then cut to desired size so you don't get papercuts, and jam it in with the Fn button pressed.

I tested it myself; works beautifully.
