An office worker's phone has stopped charging entirely. At the counter the port looks empty at a glance, the customer's cable tests fine on another device, and a known-good cable changes nothing. What does the section say happens before any quote exists?

Select one answer.

• The port has reached end of life and the quote is a replacement — a receptacle that rejects two cables has failed mechanically, and since port replacement is fine-pitch rework anyway, the honest move is to book the full job now rather than waste bench minutes on inspection theater that ends at the same rework quote nine times out of ten.
• The flashlight-and-loupe look: the queue's most common fault is pocket lint compacted into a felt wall deep at the cavity floor — invisible from arm's length — and a powered-off, plastic-pick clear in gentle layers resurrects more dead ports than any part in the drawer.
• A battery health check — a pack that refuses charge presents as a dead port, and the battery tier runs before any port theory.
• A firmware refresh — charge-enable logic hangs after failed updates, and the software tier must clear before hardware is suspected.
