the crazy solution for Quanta R62 enjoy!!!
Hi my friends, today I want to share my crazy solution for fun, because I can't find the circuit (I know I can buy it) but some challenge sometimes not bad,
It's an HP 15 model “Quanta R62” and the 5V-always is missing, “NB669” It is faulty (and I do not have it in others mobo).
My idea it is using the dual step-down controller from other mobo to fix this issue, and then I choose to use the dual step down controller for N5010 (RT8205BGQW).
Why N5010? Because all necessary components are together in the same location (top side and bottom side: circuit + transistors + coils + caps).
Soldering necessary signal “VIN, enable signal “and soldering the 5V LDO and the 5V always to the coil on the HP. Finally removing nb669.
The result of my final work in the pictures.
Sometimes fun is good lol.
Hope that help someone or inspire others.
