ASUS ROG Strix Scar 15 - i9 - g533zw

[Carlos Fliess]

Hello everyone.
I'm looking for any schematic that help me to understand what's happening to my G533.
Currently it has some kind of start-up problem that, randomly, the system don't starts all internal peripherals (cpu coolers, nvme disks, display, etc). It takes like 1 o 2 days trying to power on the device to really start.

Thanks in advance

Hello, when it starts does it continues to run? or it hangs or turn off? try to run the unit with adapter inserted and with battery only, try to use known good adapter. If you can access the motherboard try to measure the always on voltage usually its a 5v or 3.3volts that is always on. it waits for the turn on button to be press to wake the unit. any beep code or cpu fan spin? try also to swap good ddr memory or clean the pins, try to measure the voltage on all coils that you can find in the board and post it here, do this at your own risk.

try also to take photos of the motherboard and place the measured voltages of the coils, also the 19v rails. maybe you are missing a 19volts rails. do a resistance check from ground to any coil that you can access make sure there is no short circuit I mean is dead short. sometimes 1 ohm or 5 ohms is ok it depends on the board design.
