Question USB Ports and bluetooth not working

Jun 5, 2020
So today i plugged my mouse again to laptop. It did that sound for connetrion of device, but it didnt work. Mouse lights started, even the red sensor on the bottom, but the cursor on screen didnt move a inch. I tried uninstalling drivers already and turning off the Allow windows to turn off this to save power feature, none of it works.

Another big problem which i an facing for a year now, but i didnt pay attention to it until now is the bluetooth. This laptop has the bluetooth feature, but it didnt work. I turn it on, but i cant connect anything to it. Wonder whys that. Hope u can help in both of these troubles.

I am using a Lenovo B50-80 laptop with Windows 7. Thanks.
