Cevap
The correct sequence for safely replacing a swollen battery is: 1) Disconnect the AC power adapter and power down the laptop completely, 2) Disconnect the internal battery connector cable from the system board, 3) Unfasten the chassis retaining screws securing the battery frame, and 4) Remove the swollen battery and place it into a certified fire-safe hazmat container.
The correct procedure begins by disconnecting external power and shutting down the laptop to eliminate live voltage. Next, the internal battery cable must be unplugged from the motherboard to isolate system power before handling internal fasteners. After the cable is disconnected, the retaining screws can be removed safely. Finally, the damaged swollen battery is carefully lifted out and stored in a fire-safe containment vessel to mitigate thermal runaway risks.
