Safety Precautions

Correct Answer: Power off the laptop and unplug it, then safely remove it from the immediate area.

When a laptop emits smoke, it indicates a serious hardware issue or potential fire hazard. The safest and most appropriate immediate response is to shut down the laptop, unplug it from any power source, and move it away from flammable materials or areas where it could cause further damage. Continuing to use the laptop risks exacerbating the problem and potentially causing a fire. Pouring water on the device could lead to electrical shock and further damage. Blowing air into the vents is unlikely to resolve the underlying issue and may even fan the flames if a fire has started inside the laptop. After ensuring personal safety and preventing immediate danger, the user should then seek professional repair services or contact the laptop manufacturer for guidance.

Correct Answer: Power off the computer and unplug it.

Before opening the case of a computer to replace an internal component, it is crucial to completely power off the computer and unplug it from the power source. This ensures the safety of both the technician and the computer components. Leaving the computer running while working on internal components can lead to electric shock or damage to the components. Powering off the computer but leaving it plugged in is not sufficient, as there may still be residual power in the system. Placing the computer on an anti-static bag alone does not address the need to disconnect the power source. Therefore, the best practice is to fully shut down the computer and remove the power cord before proceeding with any internal hardware replacements or repairs.
