So i upgraded my RAM last week and after i was done, i noticed a pinout wich makes no sense for me.



Laptop is a Razer Blade 15 Advanced 2021.

Modell: ‎RZ09-0367BGC3-R3G1



Always a little curious when i catch details like this and then i can´t sleep -.-



From pin 50 goes a line to a very small smd piece and than to two empty solder spots, the lower one connects to the top dot of solder.



What does this pinout do actually if it has a function? (Marked in red)

Is it Ground? VCC? NC? Background light vcc or gnd?



Does it serve any purpose?

I don´t see that on newer generations.







Thanks!
