A technician is tasked with replacing an internal lithium-ion battery in a corporate laptop following repeated thermal shutdowns and improper battery state reporting. Arrange the technician's actions in the correct sequential order from first step to final step to safely complete the replacement and power system initialization.
- 1Disconnect the external AC power adapter and remove all attached external peripheral devices.
- 2Remove the bottom chassis panel and disconnect the internal battery cable connector from the motherboard header.
- 3Press and hold the laptop system power button for 15 to 30 seconds.
- 4Unfasten the degraded battery, install the new replacement battery unit, and reconnect its power cable to the motherboard.
- 5Reassemble the laptop chassis, attach the AC power adapter, and initiate a full charge/discharge cycle.
Cevap
The correct procedural sequence is: 1) Disconnect external power and peripherals, 2) Remove chassis cover and disconnect internal battery header, 3) Press and hold the power button to discharge flea power, 4) Replace the battery unit and reconnect the battery header, 5) Reassemble chassis, plug in AC power, and perform a calibration cycle.
Technicians must follow ESD and electrical safety protocols: first removing external AC and peripheral power, then disconnecting the internal battery connection, followed by pressing the power button to discharge residual capacitor energy (flea power). Only then is the physical hardware swapped. Finally, the chassis is reassembled, connected to AC power, and calibrated to update power system telemetry.
