The device has one LED Driver (SMPS) that is used to drive both display and keyboard LEDs.
The LED driver consists of two LED chains: display LED chain and keyboard LED chain. Both chains contain four
LEDs, eight in total.
The current adjustment of the driver is done from the display LED branch. The keyboard current also depends
on the display brightness.
Typically, keyboard LEDs are turned ON only in dark ambient lighting conditions.
