Disabling sleep mode on your MacBook can be useful in specific situations, but it’s essential to keep in mind that it may affect your device’s battery life and long-term health. Here’s how to turn off sleep mode on your MacBook:
For MacOS Ventura and Later:
Open “System Settings.”
Select the “Lock Screen” tab.
You will find two options: “Turn display off on battery when inactive” and “Turn display off on power adapter when inactive.” Next to each option, you can choose how long the display should be inactive before turning off. Select “Never” to prevent your Mac from sleeping.
Additionally, you can prevent your Mac from sleeping when plugged in and the display is off by selecting the “Battery” tab, then clicking “Options” and toggling “Prevent sleeping on power adapter when the display is off” to “On.”
For Prior Versions of MacOS:
Select “System Preferences”.
Choose the “Energy Saver” icon (or “Battery” for newer MacOS versions).
In the “Battery” tab (which should be selected automatically), you’ll find the “Turn Display Off After” section, which sets the time before the display turns off when there’s no activity. To disable this feature, drag the slider to “Never”.
A warning window will appear, indicating that the MacBook may consume more energy with these settings. Click “OK” to confirm the change.
Below the slider, you can disable additional settings such as “Put hard disks to sleep when possible,” “Slightly dim the display while on battery power”, and “Enable Power Nap while on battery power.”
Select the “Power Adapter” tab and drag the slider to “Never.” You can also turn off settings below, except for the first one: “Prevent computer from sleeping automatically when the display is off”.
To Turn Off Schedule (Prior to MacOS Ventura):
In the Energy Saver settings, select the “Schedule” button.
Untick the boxes for “Start up or wake” and “Sleep”. Then, click “OK” to save the changes.
Keep in mind that disabling sleep mode can impact your MacBook’s battery life and overall health. If your MacBook is always operational without sleep, it may affect the battery’s longevity. It’s essential to consider your specific needs and usage when deciding whether to disable sleep mode.
