Answer
The correct sequence for safely replacing an internal swollen battery is: 1) Disconnect external AC power and shut down the laptop; 2) Remove the bottom enclosure panel; 3) Disconnect the internal battery power harness from the motherboard; 4) Unfasten and place the swollen battery in a fire-safe container; 5) Install the replacement battery, connect its harness, and secure the chassis cover.
The proper ordering prioritizes safety and electrical protection: disconnect external power first, open the enclosure, isolate internal electrical energy by disconnecting the battery connector from the motherboard, safely extract and contain the hazardous swollen battery, and finally install the replacement and close the chassis.
