A laptop's badge reader, which uses near-field communication, does nothing after the palm rest was opened. The small cable at the reader is unplugged. Which reconnection restores it?
Select an answer to reveal the explanation.
Short Explanation
The badge reader has its own lead, and that lead is off after the palm rest was opened. You reconnect the near-field reader's cable. The camera, the battery, and the cellular tray are not the badge sensor.
Full Explanation
A near-field badge reader is a separate module, and its cable has to be seated before a tap is seen. The cable at the reader is unplugged, so reconnecting it restores the reader. The camera cable feeds the camera. It does not carry badge taps. The battery powers the laptop. It is not the near-field radio, and the rest of the machine is not described as dead. A SIM is a cellular identity. It does not read an employee badge. Exam caveat: seat the tiny connector straight. A loose latch will fail the next tap even if it looks closed. Operational check: reconnect the cable, tap a test badge, and confirm the reader responds before you close the palm rest. Close the palm rest only after a badge tap works. Record the result on the ticket.
