Common Computer Myths

Myth: It is bad to turn off the computer.
Truth: Computers are now designed to handle 40,000 on/off cycles. This is considerably more cycles than the average user will initiate in the computer’s 5-7 year life span. Turning your computer off helps reduce heat stress and wear on the system.

Myth: Turning your computer off uses more energy than leaving it on.
Truth: The surge of power used by a CPU to boot up is far less than the energy used by the unit when left on for over 3 minutes.

Myth: Screen savers save energy.
Truth: Screen savers were originally designed to help protect the lifespan of monochrome monitors which are now technologically obsolete. Most screen savers do not save energy unless they actually turn off the screen or, in the case of laptops, turn off the back light.

Myth: Network connections are lost when a PC goes into low-power/sleep mode.
Truth: Newer computers are designed to sleep on networks to prevent loss of data or connection. CPU’s with Wake on LAN (WOL) technology built-in to network cards can be left in sleep mode overnight to wake-up and receive data packets sent to the unit.
