Are you tired of your MacBook screen dimming every time you’re on battery power? Worry not, because there’s an easy fix to keep your display bright and clear, even when unplugged. In less than 100 words, here’s what you need to do: navigate to your System Preferences, select the Energy Saver settings, and adjust the brightness slider or uncheck the box that says “Slightly dim the display while on battery power.” Now, let’s dive into the step-by-step tutorial to ensure you don’t miss a thing.

Step by Step Tutorial: How to Stop Dimming MacBook Display on Battery

Before we get into the nitty-gritty, let’s quickly chat about why this is important. When your MacBook dims its display on battery power, it’s trying to save energy so you can work longer without charging. But sometimes, you need that extra brightness, right? So let’s tweak some settings to make sure your screen stays bright.

Step 1: Open System Preferences

First things first, click on the Apple logo on the top left corner of your screen and select “System Preferences.”

This should be straightforward, but if you’re new to Mac, the Apple logo is like a home button that gives you access to all kinds of settings and options for your device.

Step 2: Select Energy Saver

Next, find the lightbulb icon labeled “Energy Saver” and click on it.

This is where you’ll find all the settings related to power usage and battery life. It’s a handy place to explore and get familiar with if you’re keen on optimizing your MacBook’s performance.

Step 3: Adjust Brightness Slider or Uncheck Box

Now, look for a brightness slider or a box that says “Slightly dim the display while on battery power” and adjust or uncheck accordingly.

If you have a slider, you can set the brightness to your preference. If there’s a box to uncheck, simply click it, and voilà! Your display will no longer dim on battery power.

After completing these steps, your MacBook display should stay bright even when you’re not plugged in. This means you can enjoy a consistent screen brightness whether you’re at a cafe, in the library, or tucked away in your cozy home office.

  • Make sure your MacBook is updated to the latest version of macOS; sometimes these settings can vary with updates.
