Mini Lesson

Every time you use a computer, tablet, or any digital device, there is a right way — and a wrong way — to turn it on and off. Following the correct steps keeps your work safe and protects the device from damage.

Turning a device ON — the start-up steps

  • Step 1: Make sure the device is plugged in or has enough battery.
  • Step 2: Press the power button once — do not hold it down or press it multiple times.
  • Step 3: Wait for the device to fully load. A loading screen or logo usually appears first.
  • Step 4: Log in with your username and password if required.
  • Example: Press the power button once, wait for the desktop, log in, and begin.

Turning a device OFF — the shut-down steps

  • Step 1: Save your work — close or save any open documents or programs.
  • Step 2: Go to the Start menu (or power icon) and choose Shut Down.
  • Step 3: Wait for the screen to go dark — do not press the power button until the screen is fully off.
  • Step 4: If using a laptop or tablet, close the lid gently after the screen turns off.

Why does the shut-down order matter?

  • Holding the power button to force-quit can corrupt files — your saved work may be lost or broken.
  • Unplugging the device without shutting down first can damage the operating system.
  • Proper shut-down lets the computer finish its tasks and store everything safely.

Caring for the device when it is off

  • Store laptops and tablets flat or in a case — never pile books on top of them.
  • Keep devices away from water, food, and direct sunlight.
