Question

a new laptop was delivered to your home and left on the porch while you were at work. it is very cold outside, and you dont know how long it has been there. you unpack the laptop. you would like to know if it is working properly. which of the following is the best action to take?
place the laptop next to a heater set to high.
turn on the laptop and run self - diagnostic tests.
blow compressed air into the cooling parts before turning the laptop on.
let the laptop warm up to room temperature before turning it on.
visually inspect the lcd screen for cracks before turning the laptop on.

Explanation:

To check if a cold - delivered laptop is working properly, running self - diagnostic tests is the best way. Placing it next to a heater can damage it. Blowing compressed air before turning on may not check if it works. Letting it warm up doesn't test functionality. Visual inspection only checks the screen, not overall functionality.

Answer:

Turn on the laptop and run self - diagnostic tests.
