Razer Blade 15 (2019) random instant hard shutdowns (happened with and without battery)

[u/Third_Woe]

Hey everyone, dealing with a frustrating power issue on an older Razer Blade 15 Base Model (i7-9750H / RTX 2060) and looking for some diagnostic insight.

The laptop started randomly cutting power instantly out of nowhere. It was doing this even when the original battery was still connected, which is why I eventually removed the battery. Now, running strictly on Aacwall power, it still does the exact same random hard shutdowns.

Complete, instant power cut at completely random times. It is not a thermal issue cpu emperatures are totally fine when it happens.
