     Answers Explanation & Hints: Liquid crystal displays (LCDs) use more power than light-emitting diode (LED) or organic LED (OLED) displays. Both LCDs and LEDs use backlights, but LCD screens could use either a cold cathode fluorescent lamp (CCFL) or LED backlight.

7. A technician is trying to determine the cause of a laptop problem. Which of the listed activities is an example of the technician testing a theory?

   • The technician uses an AC adapter to power the laptop.
   • The technician asks the user the time the user first noticed the problem.

     Answers Explanation & Hints: The first three steps of the troubleshooting process are to identify the problem, establish a theory of probable cause, and test the theory to determine the cause. During the third step, the technician is taking action on what is believed to be what is causing the problem such as using an AC adapter with a laptop. When a technician is questioning the user, the technician is trying to identify the problem. If the technician suspects that the battery does not have a charge, will not keep a charge, or that there might be loose cable connections, the technician is thinking through common laptop problems.

    • S3
    • S4
    • S1
    • S0

S4 – CPU and RAM are off (and RAM contents saved to a temp file). S5 – The computer is off.
