Non-working USB ports on different MacBooks and PC Laptops can be caused by various reasons…

Possible Issues On MacBooks & PC Laptops

Non-working USB ports on MacBooks can be a frustrating problem, hindering your ability to connect essential peripherals like external drives, keyboards, and mice. Understanding the potential causes of USB port issues can help you troubleshoot and fix the problem effectively. At our repair company, we specialize in diagnosing and resolving these hardware and software issues to keep your MacBook or PC functioning at its best.
cause 1

Software Glitches

Often, USB port issues are caused by software glitches. An outdated macOS or corrupted system files can prevent the ports from recognizing connected devices. Performing a system update or resetting the System Management Controller (SMC) can often resolve these software-related problems.
cause 2

Hardware Damage

Physical damage to the USB ports is another common issue. Over time, frequent plugging and unplugging can wear out the ports, or accidental impacts can damage the internal connections. If the USB ports are loose or visibly damaged, professional repair is typically required.
cause 3

Internal Damage

Damage to the motherboard is another common USB port problem. In new MacBook models, CD 3215 and CD 3217 chips are responsible for the correct operation of USB ports and charging, and if one of the USB-C ports fails due to a liquid spill or short circuit, then all USB-C ports stop working.
cause 4

Power Supply Issues

Insufficient power supply to the USB ports can also cause them to stop working. This can happen if multiple high-power devices are connected simultaneously, or if there's an issue with the MacBook’s power management system. Resetting the SMC can help restore proper power distribution.
cause 5

Driver Problems

Implementing preventive measures can help mitigate the impact of future water spills. Use waterproof cases and keep devices away from water-prone areas. Regularly inspect and maintain your electronics to identify potential vulnerabilities. Educating yourself and others about safe handling practices can further reduce the risk of water damage.
cause 6

Peripheral Issues

The problem might not always be with the MacBook’s USB ports. Faulty or incompatible peripherals can cause USB ports to malfunction. Testing the ports with different devices can help determine if the issue lies with the MacBook or the peripherals.
