Apply freeze spray or use a thermal camera. The faulty component (usually a cracked ceramic decoupling capacitor or a shorted high-side MOSFET) will glow hot or melt the frost instantly.
Older revisions are prone to cracked or dry solder joints. Reheating specific areas (reflowing) is a common DIY fix for intermittent power issues. Charging Issues:

Have you ever come across an obscure, alphanumeric designation like "E89382 HannStar J MV4 94V-0" printed on a computer motherboard and wondered what it means? You are not alone. For many technicians, this string of characters represents a significant barrier to entry when a non-working laptop arrives on their bench. Laptop manufacturers often obscure their real PCB model numbers, leaving cryptic codes that are nearly impossible to trace on the open web.
If you are dealing with a dead or malfunctioning laptop motherboard marked with the identifier and E89382 , you are likely dealing with a, often found in older Acer, MSI, or Sony Vaio laptops. This identifier actually refers to the PCB manufacturer and its flammability rating , not the specific motherboard model. Apply freeze spray or use a thermal camera
Before injecting voltage or measuring resistance, inspect the board thoroughly.
