Problem Description:


Lenovo notebooks have 3 USB ports, two of which are unavailable on one side and one on the other. Tried to reinstall Win10 can not solve the problem.





problem analysis:


Reinstalling the system will not solve the problem, which means this is not a software problem, it is a hardware problem.
In other words, this is because the motherboard of Lenovo notebook is broken.
It can also be said that there is a problem with the USB port of the motherboard.




solution:


1. If it is still within the warranty period, you can directly find the official after-sales of the notebook and repair it for free.


2. If the warranty period has passed, you can choose to pay for repairs or buy a USB3.0 HUB hub directly.
