13英寸2016年末款双Thunderbolt3端口MacBook Pro仅单USB-C可充电求助

Hey there, let's work through this charging issue step by step. The fact that the port still charges your phone is a great sign—it's not completely dead, it just can't handle the higher power delivery (PD) your MacBook needs right now. Here are the most effective fixes to try:

• Swap in your working charger and cable first
  Even though the port works for your phone, laptop charging requires more wattage than a mobile device. Grab the exact charger and cable that works with your other USB-C port and test it on the problematic one. Sometimes a cable can handle low-power phone charging but fails at the higher wattage your MacBook demands.

• Reset the System Management Controller (SMC)
  The SMC handles all power-related functions on Intel-based Macs like your 2016 MBP, so this is the go-to fix for charging oddities. Here's how to do it:

  1. Shut down your MacBook completely.
  2. Press and hold the left-side Shift + Control + Option keys, plus the power button, all at the same time for 10 full seconds.
  3. Release all keys, then press the power button to boot your Mac back up.
     Once it's on, test the charging port again with your working charger setup.

• Clean out the port (gently!)
  Dust, lint, or tiny debris can build up in the USB-C port over time. These might block the specific pins used for high-power laptop charging, but still leave enough contact for lower-power phone charging. Grab a soft, dry toothbrush or a can of compressed air (hold it upright to avoid spraying liquid) and gently clean out the port. Don't push debris further in—go slow and be careful.

• Update macOS to the latest compatible version
  Sometimes firmware or software bugs can mess with port functionality. Your 2016 MBP can run up to macOS Monterey, so head to System Preferences > Software Update and install any available updates. This often fixes hidden glitches that affect charging.

• Test in Safe Mode
  Third-party apps or kernel extensions might be interfering with the port's ability to charge your laptop. Boot into Safe Mode by:

  1. Shutting down your MacBook.
  2. Turning it on, then immediately holding the Shift key until you see the login window.
  3. Log in (you might need to log in twice), then test the charging port.
     If it works in Safe Mode, you'll need to uninstall recently added apps or extensions to find the culprit.

• Run Apple Diagnostics
  This tool can detect hidden hardware issues. Here's how to use it:

  1. Shut down your MacBook.
  2. Turn it on, then immediately press and hold the D key until you see the language selection screen.
  3. Follow the on-screen prompts to run the diagnostics.
     If it flags a problem with the Thunderbolt/USB-C port, you'll need to reach out to Apple support or an authorized repair center for further help.
