Intel CPUs have supported Thunderbolt since the 4th generation and Thunderbolt has become widely available since 2020. Most laptops now support Thunderbolt since Thunderbolt 3 provides up to 40 GB of bandwidth. In addition, the popularization of e-sports has allowed external GPUs to become mainstream. However, compatibility issues with these products have also become a main concern for users.
Issues and Solutions for External GPUs
As a certified Thunderbolt laboratory, Allion partners with major computer system manufacturers.
By running a large amount of tests, we found an issue that caused laptop touchpads to stop working after an AMD external GPU was connected. This issue negatively affected the user experience and users did not know how to solve this problem.
After Allion’s professional teams analyzed the issue, it was found that the cause of the failure was due to a conflict between the touchpad’s driver and external GPU. Here’s how to solve it.
- Enter Device Manager to uninstall then reinstall the touchpad driver under Human Interface Device (shown below)
- Update the Touchpad’s driver
