We all know what it’s like to forget the charger for your laptop at home when you’ve planned to go out and work. There’s not much you can do apart from changing the power settings. It is also helpful to reduce the strain on your battery and increase its lifespan.
Below we outline a few ways in which you can alter the power settings of your Mac — whether to make it save energy or spend more of it.
How to change power settings on MacBook
Mac power options are located in the Energy Saver section of System Preferences. To find them, go to the Apple menu in the top left corner of the screen, open System Preferences, and click on the lightbulb icon. Here, you can set up your MacBook in such a way that it uses less energy without any manual effort.
You can introduce several changes:
- Drag the slide bar on top of the window to set the amount of time after which your display turns off. It can be anywhere from one minute to three hours. If you drag it all the way to the right, you can prevent it from turning off whatsoever. You can change these settings both for when your Mac is powered by the battery and connected to the charger by switching tabs on top of the window.
- You can set the sleep and wake patterns for your Mac. In the bottom right corner of the window, click on Schedule to open a menu where you can set the time for your Mac to start up and go to sleep. Bear in mind that a scheduled startup only occurs when your Mac is connected to a charger.
- Power Nap is a function that allows your Mac to perform certain small background tasks without interrupting sleep mode. These functions include checking your mail, installing updates for macOS, saving the current processes, and making backups. This requires more energy than the regular sleep mode, but less than the normal activity of your computer.
- If other users on your Mac have access to common resources and connected devices, turn on the automatic feature of temporarily exiting sleep mode when getting a request.
When connected to a power adaptor, videos can automatically play in the standard range (SDR) that requires less energy than HDR. Finally, when your Mac is on without internet access you might experience the display dimming automatically.
To set Mac power settings to the appropriate level, keep an eye on the amount of battery charge left on your laptop.
Manage sleep settings: Put hard disks to sleep when possible
By choosing the Put hard disks to sleep when possible on your Mac you can save a substantial amount of energy. This makes your Mac not to use the hard disk for some time. However, solid-state drives don’t have any mobile elements, so this function does not apply to them (this goes for almost all of the recent Mac models).
You won’t be able to turn off the hard drive when the laptop is using an app or a media file stored on it since these processes require continuous access to the disk.
How to put the disk to sleep:
- Go to Apple menu → System Preferences → Energy Saver
- Tick the box next to Put hard disks to sleep when possible in the Battery tab
- Tick the same box in the Power adaptor tab
Can you put your Mac on low power mode?
When it comes to lowering the energy consumption when the computer is turned on but isn’t being used for anything, you can easily turn on the sleep mode. There are three ways of doing that:
- Simply close your MacBook
- Press Command (⌘) + Option + Power button simultaneously
- Go to the Apple menu and select Sleep
How do I reduce the power consumption of my MacBook Pro?
There is no such thing as low power mode in MacBook Pro that can be activated by a shortcut. However, that doesn’t mean that the user can’t manually change the power settings in a way that will lower the energy use. For example, you can close any apps that you don’t use, lower the brightness of your screen, etc.
