I am working on MSI GL63 that also has 16P51 (Rev 1, I think) board.
This is gaming laptop.
Last few weeks, I have been noticing following symptoms -
1. When the laptop is switched on, the power button shows blue light for a long time. The machine may or may not boot after the time. (Usually, when the power switch is pressed, it would show blue light for couple of seconds. After that, the keyboard LEDs (RED Color) turn on and the power switch shows red light, machine boots)
2. The laptop may try to boot by doing power cycling 3, 4, 5, 6... times. However, no guarantees that machine will boot and even if it boots, the laptop turns of anytime and goes back to the blue light start sequence in Point 1.
I am wondering what the reason could be. Since machine boots, almost normally or after an undefined delay, my thought is the power rail controllers are affected.
I am of the opinion that the problem could be in capacitors in the Time delay circuits in power sections that are used to ensure power rail stabilization before key parts (CPU, GPU etc.) get powered. However, I am going to start on this machine and have no evidence to support this thought.
Other possibility is key controller chips (+3 and +5 volts) that switch on the control voltages, failing intermittently. Again, a thought but no specific evidence.
However, what I would like to know from esteemed knowledgeable people here is, whether they have faced such situation? If yes, what caused it. This would certainly help me in building my action plan.
Warm Regards,
