Answer

If a Thunderbolt™ device connected to your MSI laptop has an unstable connection, is not detected, or does not perform as expected, the issue is usually related to the driver version, firmware, or cable quality. Follow the steps below in order to restore a normal connection.

This article applies to all MSI laptops that support Thunderbolt.

How to Check Whether the Laptop Supports Thunderbolt

Go to the MSI website, look up the specifications for your laptop model, and check the "I/O Ports" section.

Troubleshooting Steps

1. Remove the existing Thunderbolt driver, then go to the product download page on the MSI website and install the latest driver.
   
   Please refer to [How To] Install the Thunderbolt Device Driver
   
   *If no Thunderbolt device driver is available on the MSI website, the model does not require a separate Thunderbolt driver.


2. Check the MSI download page for the latest BIOS or Thunderbolt firmware and install any available updates.


3. Go to the official website of the Thunderbolt device, such as an external GPU enclosure or docking station, and install any available firmware updates.


4. Test the connection with another Thunderbolt-certified cable.


5. Connect the Thunderbolt device to another computer for testing.
   
   If the device works normally on another computer but the issue persists on the MSI laptop, contact your local MSI service center for further assistance.

FAQ

Q: Why is my Thunderbolt device not detected or repeatedly disconnecting?

A: Common causes include an outdated driver, a non-certified cable, or incompatible device firmware. Insufficient power may also cause the issue. Make sure the external device is connected to its dedicated power source, if required.

Q: Can I use a standard USB-C cable if it looks the same?

A: Because Thunderbolt technology has high requirements for bandwidth and signal integrity, it is recommended to use cables that meet specifications or are certified in order to ensure Thunderbolt functionality, bandwidth and stability.
