Solid-state component in a mobile phone maintains proper voltage levels in the circuits C. diodes
Electronic devices called capacitors store electric charge. They allow a mobile phone to store data such as phone numbers, even if the battery is removed for a short time. Diodes maintain proper voltage levels in the circuits.
Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators. The fundamental property of a diode is its tendency to conduct electric current in only one direction.

Answer:
Let the computer warm up to room temperature before turning it on.
Explanation:
The laptop has been shipped to the user's home when he were at work and found on the deck. Outside it is really cool and he don't remember how long it has been there. Then, the user open his laptop and want to know whether it is functioning properly. Instead, let the machine warm up while switching it on to room temperature.
When a computer is still in a cold climate, they have to let it heat up to room temperature apx. 6-24 hours before switching it on. Otherwise, its heat the elements generate could cause water moisture within the laptop. That water could then harm elements of the system.
