Solve : Light indicators not working correctly on laptop's keyboard?

1.	Solve : Light indicators not working correctly on laptop's keyboard?
Answer» I noticed on my THINKPAD L590 that the light indicators don't turn on/off correctly on caps lock, numlock, etc. Usually when I click the button, the light doesn't turn on (the button works anyway). Sometimes they turn on by themselves and start blinking (turning on and off). Sometimes multiple of them start blinking at the same time (capslock, numlock, F4 for mic). What I also noticed is that, they don't stay turned on, they may turn on randomly, but turn off fast after that. I don't know what's going on, the lights seem to work on their own, backlit works correctly. is updated, also updated from Vantage. I tried reinstalling KEYBOARD drivers, but it didn't FIX it, safe boot also doesn't help. I'm guessing it's a hardware problem, but I don't know why none of them work correct, except the power on button indicator which is not part of the keyboard.Where are the drivers from ? ? Quote from: patio on November 01, 2020, 06:31:10 AM Where are the drivers from ? ? I tried updating keyboard drivers in device manager, but they are up to date. Some drivers were INSTALLED in window's updates and some from Lenovo's Vantage app, not sure if drivers for keyboard.They should only come from Lenovo...not device manager...but it sounds like a physical issue.I also updated BIOS, but I'm not sure if indicators worked before that, I think they did.My console was supplanted as of late and none of the pointer lights are working aside from when the PC is charging that the battery LED MARKER turns on.

I tried updating keyboard drivers in device manager, but they are up to date. Some drivers were INSTALLED in window's updates and some from Lenovo's Vantage app, not sure if drivers for keyboard.They should only come from Lenovo...not device manager...but it sounds like a physical issue.I also updated BIOS, but I'm not sure if indicators worked before that, I think they did.My console was supplanted as of late and none of the pointer lights are working aside from when the PC is charging that the battery LED MARKER turns on.
