Re: can i configure backlit keyboard on a P51 to be always on

2019-08-05, 7:47 AM

Hi folks.

 

Searching for information on this issue for the Yoga c930 has inexorably led me to this topic! I was willing to try the solution on this machine but Keyboard_Core.dll does not exist anywhere. I do have Vantage and the toolbar installed and I can toggle the backlight via the toolbar so obviously the capability is there, somehow, it's maybe just a different version of Vantage? Any ideas appreciated. :smileyhappy:

Any updates on an ETA for the next version?  It looks like most of the major issues have been fixed, this is a great project!  Plan to use again once the bug preventing restart/shutdown is resolved.

Hey, not sure what happened to @JooJooBee666, here are compiled binaries, please use original installer and replace files in C:\Program Files\LBCService with contents from this archive.

Hi,

 

Sorry, but it looks like this version is not working better, at least on my T480. 

For instance: I can change the settings from the GUI app, though whenever I try to save them, it's not working, the old values remain. In addition, when I boot the laptop, the keywoard backlight stays off, even if defined properly in the defaulted settings. 

 

I think I'm done here with this tuning attempt. I'll keep using this Thinkpad with the standard package that doesn't offer a clever backlight management for the keyboard. Not great but it will do. 

 

Many thanks to all the contributors, a substantial work has been achieved here. 

 

Cheers!

Thanks a lot, that works on my T495!

 

You (or @JooJooBee666) might do other users a huge favour to provide an updated installer including these fixes ;-)

 

Concerning the annoying OSD issue: The current version of Lenovo Vantage seems to run without tposd.exe. There is however a service called TPHKLOAD but killing it also shuts off other functionalities like the mic mute key.

I got rid of the OSD notifications by following this method using the windows advanced screen settings (not exaclty as depicted but it's self explaining):

 

How to remove Caps Lock indicator from displaying permanently on desktop screen - Windows 7 - ThinkPad, Lenovo V/B/K/E series laptops

 

 

 

BTW: If some Lenovo Mod might be reading this thread: Please (!!!) tell this whole backlight thing to the Vantage App developers.I'm glad some geeks found a way but I expect such basic features to be there out of the box!

Hi guys,
the solution i posted a while ago in still working for me using AHK scripting and thinkpadlightv02.exe.

The post I am referring to is here:

https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile-Workstations/can-i-configure-backlit-keyboard-on-a-P51-to-be-always-on/m-p/3949273?page=1#4104705

Lenovo changed the way the Keyboard_core.dll works.
details are depicetd here:
https://github.com/ligius-/lenovo-backlight-control/issues/5

The patched thinkpadlightv02.exe
is released here:
https://github.com/ligius-/lenovo-backlight-control/releases

Just replace the existing .exe with this one provided and everything should work again.
Thanks for ligius- providing the program!
