Cevap
The correct sequence of steps is: 1) Disconnect the external AC power adapter and shut down the laptop completely, 2) Remove the bottom base cover screws and detach the lower panel, 3) Disconnect the internal battery cable connector from the system board, and 4) Unfasten the battery retaining screws and remove the battery unit from the chassis.
When performing internal hardware servicing on a modern laptop, technician safety protocols mandate isolating power sources in a strict order: first disconnect external AC power and power down, remove the outer bottom casing, immediately disconnect the internal battery cable from the motherboard to de-energize circuits, and finally unbolt and extract the physical battery unit.
