The correct answer is B.
OBJ-5.5: Based on the symptoms provided (laptop shutting down whenever it is moved), it is most likely a loose battery connection causing the issue. If the battery connection wasn’t loos and the laptop was unplugged, the laptop would continue to run on battery power. Overheating can cause a laptop to shutdown, but it wouldn’t necessarily happen each time the laptop is moved. If the CMOS battery fails, it will not cause the laptop to shut down, but instead will cause the laptop to lose the correct date/time.
