Yup. Had an MacBook Air. Slight water damage near charging port. Laptop functioned correctly on AC power. Extensive battery diagnostics: Healthy. Just the charging circuit saying "go ahead, charge device"...

At the Genius Bar expected something reasonable, realistic... $300? Parts and labor.

"So we have a quote for you, $950. Perhaps we go out and look at the new Macs together?"

90% of the cost of the laptop to replace the charging port.
