This wikiHow teaches you how to boot up your computer in general (also called a PC) in both normal and “safe” test mode. Safe mode will only load the default programs to your computer, not start the program when you log in, and reduce the display quality of the computer.
Steps
Start the computer in normal mode
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/29/Start-a-Computer-Step-1-Version-2.jpg/v4-460px-Start-a-Computer- Step-1-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/29/Start-a-Computer-Step-1-Version-2.jpg/ v4-728px-Start-a-Computer-Step-1-Version-2.jpg”,”smallWidth”:460,”smallHeight”:348,”bigWidth”:728,”bigHeight”:551,”licensing”:” <div class=”mw-parser-output”></div>”}
Make sure your computer is plugged in. If it’s a desktop computer, you won’t be able to turn it on if you don’t plug it in first; Laptops can run on batteries, but you should also plug them in to avoid low battery or other problems when starting up.
- If you are plugging your computer into a surge protector (such as a long outlet) instead of a traditional wall outlet, you need to make sure the surge protector is turned on.
- Laptop charging cords usually plug into the left or right side of the chassis.

Identify the computer’s power button
{“smallUrl”:”https://www.wikihow.com/images_en/5/5d/Windowspower.png”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5d/ Windowspower.png/30px-Windowspower.png”,”smallWidth”:460,”smallHeight”:460,”bigWidth”:30,”bigHeight”:30,”licensing”:”<div class=”mw-parser-output” “></div>”}
. The power button has a circular icon with a vertical line through the top. The location of the power button varies from computer to computer, but will typically be in one of the following locations:
- With a laptop – Located on the left, right or front of the body. Sometimes the power button is also designed like a key near the top of the keyboard, or as a button located in the area above / below the keyboard.
- With desktop computers – At the front or back of the CPU head, this is a box-shaped piece of hardware that is connected to the computer monitor. Some iMac desktops have a power button located on the back of the screen or keyboard.

. You don’t have to hold down the power button to turn on the computer. Normally, the computer will start making the sound of the internal cooling fan along with the spinning sound of the drive; After a few seconds, the screen will light up and show the boot or login screen, depending on whether the computer is shutting down or hibernating (sleep).
- With laptops, you need to open the screen up from the body to turn on the screen.
- If the desktop won’t turn on, try pressing the monitor’s power button. It is possible that the computer is on but the monitor is not.
