3.Disconnect your computer and peripherals from their power sources. Also, dis- connect any telephone or telecommunication lines from the
computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:

Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
