Fixing a MacBook Pro Battery That Won’t Charge Without Reason
## Direct Answer
To fix a MacBook Pro battery that won’t charge without reason, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU), updating your operating system, and checking for dust or debris in the charging port.
## Step-by-Step Guide
1. **Reset the SMC**: Shut down your MacBook Pro, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button. Press and hold these keys while powering on your MacBook Pro. Hold them for 10 seconds, then release. This process resets the SMC.
2. **Update your operating system**: Ensure your MacBook Pro is running the latest version of macOS. Go to System Preferences > Software Update to check for updates.
3. **Check the charging port**: Inspect the charging port for dust or debris. Use a can of compressed air or a small brush to clean out any blockages.
4. **Reset the PMU**: This step is only applicable to older MacBook Pro models. Shut down your MacBook Pro, locate the power button, press and hold the power button for 5 seconds, then release.
5. **Check the battery health**: Go to Apple Menu > About This Mac > System Report > Hardware > Power. Check the “Condition” of your battery. If it’s “Normal”, the issue might not be with the battery itself.
6. **Try a different charging cable and adapter**: Rule out any issues with your charging cable or adapter by trying a different one.
