If your Mac’s keyboard has a row of physical function keys (F1-F12) running along the top of the keyboard, you’ll find the power key at the far-right end of this row. The key has a “Power” icon, which is an open circle that contains a vertical line at its center. If you’re using a MacBook with Touch Bar and/or Touch ID (such as some MacBook Pros and MacBook Air models from 2018 and later), the power button is a solid black touch key at the top-right corner of the keyboard.

Depending the model, you may also be able to power on the laptop by pressing any key on the keyboard. If your Mac won’t turn on, see the Troubleshooting a Mac That Won’t Turn On method.

If you have any peripherals physically connected to your Mac, including USB hubs and drives, remove these first.

Make sure the part of the power cord that plugs into your computer is also securely attached. It shouldn’t jiggle around or have any frayed cables. If you’re using a power strip, plug directly into the wall outlet instead. Sometimes power strips have burned-out outlets or fail entirely. Some wall outlets are controlled by light switches, meaning that if you flip off a switch, it’ll also turn off the power outlets. Try the light switch(es) in the room to see if they need to be in different positions for the outlet to work.

Most Mac keyboards have two keys with suns on them—one lowers the brightness and the other raises it. It’s the larger sun on the right that raises the brightness. If your keyboard has F keys at the top, it’s usually F2. Some keyboards do not have keys that control the brightness of the display.

If you’re using a TV as a monitor, make sure it is set to the correct source or input. For example, if your Mac is connected to your TV’s HDMI-2 port, you’ll usually have to use the TV remote control to switch the source/input to HDMI-2.
