''If your laptop is heating up near the power and volume buttons, consuming battery faster, and a diagnostic shows a problem with the Thunderbolt hardware, it sounds like there's a hardware issue that needs professional attention.''
''Here are some things to consider and next steps:''
# ''***Thunderbolt Hardware Issue***:''
** ''Since the diagnostic indicates a problem with the Thunderbolt hardware, this could be causing increased heat and power consumption. Thunderbolt ports handle high-speed data transfer and external display connections, which can generate heat when not functioning properly.''
# ''***TG Pro Temperatures***:''
** ''TG Pro is a helpful tool for monitoring internal temperatures. High readings in specific areas, especially around the Thunderbolt ports or the power circuitry, might indicate overheating. Pay attention to temperatures above 90°C (194°F) for CPU or other major components, as these can lead to hardware damage if sustained.''
# ''***Battery Life Impact***:''
** ''With increased heat, the laptop's fans might be running more, and components might be working harder to compensate for the hardware issue, leading to faster battery drain.''
''Given that you've already tried Apple-recommended processes, your best course of action is:''
# ''***Backup Your Data***:''
** ''Ensure you have a current backup of all your important data, just in case more serious hardware failures occur.''
# ''***Contact Apple Support or Visit an Apple Store***:''
** ''Since the diagnostic indicates a hardware issue, it's best to get professional help. Contact Apple Support for further guidance, or bring your MacBook Air to an Apple Store or Authorized Service Provider for repair or replacement. Describe the problem in detail, including the diagnostic results, to help the technician identify the root cause.''
# ''***Avoid Using Thunderbolt Ports***:''
** ''If possible, avoid connecting devices to the Thunderbolt ports until the problem is resolved, as using them might exacerbate the issue.''
# ''***Monitor for Further Issues***:''
** ''Continue monitoring your MacBook Air for other signs of hardware problems, like sudden shutdowns, screen glitches, or further overheating. If these occur, mention them to the technician during your service visit.''
