How can you totally protect a PC from damage during an electrical storm? A. Disconnect the AC power cable B. Disconnect all external cables and power cords C. Use a surge protector D. Turn off the AC power E. None of the above

The correct answer is: A. Disconnect the AC power cable.

A surge protector is a device that is designed to protect electrical devices from power surges. However, it is not 100% effective. In the event of a severe power surge, a surge protector may not be able to protect your PC. The best way to protect your PC from power surges is to disconnect the AC power cable. This will ensure that no power is flowing to your PC and that it will not be damaged by a power surge.

Here are some additional tips to protect your PC from power surges:

• Use a surge protector that is UL-listed. This means that it has been tested and certified by Underwriters Laboratories to meet certain safety standards.
• Keep your surge protector clean and free of dust. Dust can build up on the surge protector and create a fire hazard.
• Inspect your surge protector regularly for damage. If you see any damage, replace the surge protector immediately.
• Unplug your PC from the surge protector during thunderstorms. This will protect your PC from power surges caused by lightning strikes.

I hope this helps!
