Keeping keyboard backlit ALWAYS ON on X270

2017-09-02, 12:40 PM

Hi,

 

as a long-term Dell Latitude user, I had to switch to Lenovo ThinkPad with a new employer. I was used to have keyboard always on (and the keyboard was really always backlit when laptop was on).

 

On ThinkPad, the keyboard goes always OFF when laptop goes to sleep or power off. While starting/resuming the laptop I always have to turn the backlit keyboard MANUALLY on.

 

How can I keep the keyboard backlit always on?

 

(there are some other related topics on this forum but none is related to ThinkPad X series)

 

Thanks,

Radek

I don't think it is as simple as editing a value. The toggle of backlight/thinklight seems to be in the very low-level keyboard routines, that are almost certainly in the BIOS code itself. That would mean that the current state is either not saved anywhere, or saved in the CMOS. Since it is lost between boots, I assume it is saved nowhere.

Best Regards....

My X270 is dual-boot Linux and Windows. When I use Linux (Debian), I can adjust the keyboard backlight in the settings app. This setting DOES persist across restarts, and seems to be saved in the operating system. As soon as Debian begins loading drivers, the keyboard backlight turns on to whatever brightness level it last used.

 

I have the same preference in Windows - to have the keyboard backlight on whenever Windows starts.

no way...this is a bios case....

Yes way. If you don't believe me, install x64 Debian and try it yourself. At a minimum it means that the backlight setting can be saved and persisted, and that the backlight can be toggled by software e.g. the Debian driver.

If there is a light icon on the Space button, it means you can turn it on. Just press Fn + Space and boom.

Do you think that someone who is asking to keep the backlight on all the time doesn't know how to turn it on in the first place? No.

Same issue here. Thinkpad T470S. Windows10.

 

Computer is administrated by my employer. Do I really have to dive into BIOS settings?

 

Thank you in advance,

Frederik

Has anyone figured this out?  I'm sick of pushing Fn+Space all the time.  Lenovo Yoga C940.
