Using the Power Button to Start Your MacBook

To turn on your MacBook, the most straightforward method is to press the power button. Depending on your MacBook model, the location of the power button may vary slightly. On recent MacBook Air and MacBook Pro models, the power button is integrated into the Touch ID sensor, located at the top-right corner of the keyboard. On older models, it is a separate key positioned in the upper-right corner of the keyboard.

Press and hold the power button for a brief moment, usually one to two seconds, until the Apple logo appears on the screen. This indicates that the MacBook is booting up. If the MacBook does not turn on immediately, ensure it is connected to a power source, as a completely drained battery can prevent it from powering up.

Using the Lid to Wake or Turn On

MacBooks are designed with a feature that turns them on or wakes them from sleep when you open the lid. If your MacBook is completely off and you open the lid, it will automatically start up without needing to press the power button.

This functionality is especially convenient for users who frequently close their MacBooks and want to quickly resume work. If your MacBook does not turn on upon opening the lid, it may be powered off, or the battery might be depleted. In such cases, use the power button or connect the MacBook to a charger.

Using External Keyboards or Devices

If you use your MacBook with an external keyboard or other peripherals, you can sometimes power on the device using these accessories, provided the MacBook is connected to power. This is particularly useful for setups where the MacBook is used in clamshell mode (closed lid with external monitor, keyboard, and mouse).

To turn on your MacBook with an external keyboard:

  • Ensure the MacBook is connected to its charger.
  • Press any key on the external keyboard or use the mouse to wake or power on the MacBook.

Note that this feature depends on the MacBook model and system settings; not all external devices support turning on the MacBook.
