A technician needs to replace a swollen Lithium-ion battery in a corporate laptop. Arrange the technician's actions in the correct chronological order from first step to last step.
- 1Disconnect the AC adapter and ensure the laptop is completely powered off.
- 2Attach an anti-static wrist strap and remove the laptop bottom casing.
- 3Disconnect the battery interface cable from the system board connector.
- 4Unscrew the retaining screws and transfer the swollen battery to an approved hazardous waste container.
- 5Secure the replacement battery, reconnect its cable to the system board, and reinstall the bottom casing.
Cevap
The correct sequence begins with disconnecting external AC power and shutting down the device, followed by applying ESD protection and removing the bottom casing. Next, the battery interface cable must be disconnected from the motherboard before unfastening and placing the swollen battery into a hazard container. Finally, the replacement battery is secured, connected to the system board, and the outer casing is reassembled.
The correct order follows standard safety and hardware replacement methodology: first remove external power (AC adapter) and power down the device, then apply ESD protection and remove the outer chassis cover. Disconnect the internal battery power connector from the motherboard before unfastening the battery retaining screws to prevent short circuits. Safely store the swollen battery in a designated hazardous waste container, then install the new battery, attach its connector, and reassemble the casing.
