@oldturkey03 Awesome Thank you!

if thats broken off and doesnt get fixed what do you think will happen?

* Shortcircuit of the board

* or non working backlight?

I accidentially broke off this tiny little thing when unplugging the speaker cable while disasembling for a battery replacement…

@chrism83 that is reference designator R8447 which is a 10K ohm 5% 1/20W resistor in a 201 package. It is part of your keyboard backlight circuit
