A customer describes a Switch that shows a charging icon for a moment, then goes dark, and never gains battery percentage overnight. The port looks clean and the cable is known-good. Which stage of the platform's power chain does this description point toward, and why?

Select one answer.

• The Tegra system on chip — a console that shows any screen content at all has proven its entire power chain end to end, so a fault that survives a working icon must live in the processor itself.
• The charging stage around the BQ24193 — the momentary icon says the port and negotiator are passing power in, but the cell never fills, which is the charger's job going undone.
• The USB-C receptacle — every charging complaint on this platform is port wear until proven otherwise, regardless of what the screen shows.
• The backlight driver — a screen that goes dark is the display path's signature, and the charging icon is a coincidence.
