Besides the useful "ThinkLight" switchable keyboard illumination for typing under dark conditions, there are other disturbing white lights directly in the field of vision on my Lenovo Thinkpad P1 Gen 2.
These lights are located on the keys Esc, F1, F4 and Caps Lock and on the power button.
Esc is shining if the Fn key is not locked.
F1 is shining if the speaker is off.
F4 is shining if the microphone is off.
Caps Lock is shining if the Caps Lock function is toggled on.
The power button is shining if the laptop is on and blinking if the laptop is off.
Not directly in the field of view but also disturbing if you want darkness are
a white lamp next to the power cable
- shining if there is a plugged cable that has power
a big red light on the back of the screen
- shining if the computer is on and blinking if the computer is off.
How can some or all of these lights be permanently switched off (except for painting or gluing)? The firmware Lenovo Vantage or BIOS do not allow such a modifications. OS Win 10.0.18363
