A screen saver or screensaver is a software program that becomes activated after the computer is inactive for a specified amount of time. Screensavers were originally designed to help prevent images or text from being burned into older monitors.
In Windows, press the Windows key+L to lock the computer if you're stepping away from the computer. Locking the computer activates the screensaver and prevents others from accessing your computer.
Are screen savers still needed?
The monitors and flat-panel displays used today no longer suffer from burn-in issues found with older CRT monitors. However, screen savers are still used for their aesthetic value and to password protect a computer when the user is away from the keyboard.
Do screen savers save power?
No. When a screen saver is visible, your computer and monitor are both still on, meaning the same amount of power is used.
You'll save power and extend the life of your monitor if you turn it off when you step away from your computer instead of using a screen saver. If you use a screen saver to show pictures or for other aesthetic reasons, adjust the power savings mode to turn off your monitor after being away for more than an hour.
