I uses Lenovo T490 and T480s at Office and home.

Both using external keyboard having Num/Caps/Scroll Lock LED feature.

When I first boot up the computer, it works well, but at sometimes, the key is pressed, but the LED doesn't work.

In other words, It's not synchroni ]]> Tue, 12 May 2020 04:34:07 +0000 https://forums.lenovo.com/topic/findpost/1300/5014841/5049731 joongtang
