Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

How long should you wait after you unplug the monitor’s power cable?

A	5 seconds
B	15 seconds
C	30 seconds
D	None of the above

Explanation:

Detailed explanation-1: -If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor. If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.

Detailed explanation-2: -Some batteries connect directly to the motherboard, and some connect via a cable. Depending on the type of battery your laptop has, you may or may not have to remove it. Hold down the Power button for 15-30 seconds. By holding down the Power button, you release all of the residual power left in the laptop.

Detailed explanation-3: -10 seconds is the time it takes most capacitors to discharge enough for the electronics they’re powering to stop working. That’s why when you turn your PC off at the wall, things like an LED on your motherboard take a few seconds to disappear.

Detailed explanation-4: -Powering the equipment off for a small period of time can allow the hardware to “reboot” and recover its self to a working state.
