What should you do before turning on a new laptop that has been left in a cold environment?

Immediately turn it on to check functionality
Let it warm up to room temperature
Plug it in to start charging
Remove the battery

The correct answer is: Let it warm up to room temperature

When a laptop has been left in a cold environment, it is essential to let it warm up to room temperature before turning it on. This is crucial because electronic components, including batteries and circuits, can be affected by extreme temperature changes. If a laptop is powered on immediately after being in the cold, moisture can condense inside the device from the warm air meeting the cold surfaces, potentially causing short circuits or damaging sensitive components. Allowing the laptop to acclimate to room temperature ensures that any condensation has a chance to dissipate and the internal components can gradually adjust to a safe operating temperature. This preventive step helps to avoid any immediate hardware failures, prolongs the lifespan of the laptop, and ensures that it functions correctly when powered on.
