Reported fault: Shutting down mid-work with a battery service warning

What we found

The machine was shutting down mid-use and reporting a battery service error, so the battery was condemned.
With the bottom case off, the internals were heavy with dust and lint — the fan intakes and heatsink areas are visibly clogged in the photos.

During the repair

MacBook Pro top case with the battery removed, showing adhesive strips and dust and lint built up around the fans and heatsink — With the battery out, the dust build-up around the fans is clear.

What we did

1Opened the bottom case and disconnected the battery.
2Removed the old battery pack from the top case.
3Cleaned the dust and lint out of both fans and the surrounding heatsink and vent areas.
4Fitted a new genuine Apple battery for the 15-inch 2015 MacBook Pro and reconnected it.
5Reassembled and checked the battery reporting in System Information — condition reading Normal and charging correctly.

The result

The MacBook Pro went back to the customer in Richmond holding charge and no longer shutting down mid-work, with the cooling cleaned out so it runs cooler under load. The battery and the work carry our 90-day warranty, and we work no-fix-no-fee.
