P52 keyboard backlight not recognized in Lenovo vantage

2019-12-22, 10:39 AM

Hi, I have a brand new Thinkpad P52 20MAS3DD00 which in it's specifications indicates backlight keyboard, and at the spacebar it has the "backlight" icon.

But touching FN + Spacebar does not enable the keyboard backlight. In fact if you enter in Lenovo vantage the keyboard backlight is missing, algo it can not be found any option in Bios related to the backlight.

I have already updated windows to it latest version (1909), also Lenovo vantage and all Lenovo drivers and Bios (latest Bios 1.31-1.16)... But still keyboard not recognized by the Lenovo vantage.

 

All other keys are working fine, including specific key lights like if you press FN + Esc (for FN lock), the Esc light get on. But the backlight of the keyboard is not working and not even recognized by the Lenovo vantage software or bios.

Maybe is something bad with the model number saved in bios : 20MAS3DD00?, maybe a value of here should be modified in order to the bios to recognize the backlight of keyboard?

Or can I force Lenovo vantage to detect the keyboard backlight?

 

Thanks in advance for your help.

Kind regards

Hi fgampel,

Can you confirm that in the machine description it mentions a backlit keyboard?

 

As far as I know, it should be. Does the keyboard briefly light up when you turn on or reboot your machine? 

 

If you have a backlit keyboard and it does not light up, contact support because the machine is defective. It could be a bad connection.

Hi @ve2mrx , yes in the machine description mentions Keyboard with white backlight, it can be chacked with the part number i attached in the first post.

Also at the spacebar in the keyboard i have the "Backlight icon" which is mentioned in all tutorials about to how to know if your Thinkpad has keyboard backlight.

And no, there is no any briefly light up at the reboot or startup, just blinking keys like "Numlock, Capslock, Fnlock".....

 

Thanks for your time

Then something is wrong with the backlight. Mine does briefly fade on and off at boot, and I can turn it on before Windows boots.

Check if Fn+F4 enables and disables the microphone. If that does not work, then the Hotkey drivers are not correctly installed. Otherwise, you might want to try to reseat the keyboard cable to the system board. If that doesn't restore the function, then place a service request for a replacement keyboard.

Hi Harrisb, what do you mean con reset the keyboard cable? I already tried to disconnect and reconnect the both keyboard flex cables, with no success.

 

In other hand, is it normal that the backlight keyboard doesn't even figure as an option in the Lenovo vantage?

I'm suspecting that maybe the Bios has not set any option related to the keyboard backlight, maybe changeling the model number with the Bios tool it could help?

 

Thanks

Does Fcn,+F4 enable and disable the microphone?

Yes, all the other option FN+Esc , FN+F4 etc etc all works. And also all that options are present in the Lenovo vantage software, so you can opt to use it by software or by keyboard (FN+....)... But keyboard backlight is not working with FN+spacebar and also does not appear in the Lenovo vantage (I'm not sure if it should appear in Lenovo vantage or not)

Hi to all, yesterday after receiving the Intel ME Firware update V12.0.49.1534 the keyboard backlight started to work perfectly. Hope this can help others.

Thanks for the time of who's tried to help me.

Kind Regards
