Hello! i know that this question was probably asked many times but i could not find a solution that fixed my problem, but i think this forum's community might be helpful.
The issue is that if i connect a mouse and a keyboard do my computer, they won't work. My laptopt is HP ProBook 450 G3.
I noticed that there are yellow triangles near the devices in the device manager, sometimes it shows 2 times the keyboard(i dunno why). In addition, sometimes the keyboard work and sometimes not. I tried to update my BIOS to the latest version,install drivers from iObit pro and it did not seem to work.
I need to point that if i connect a USB to my computer and than restart it, before the troubleshoot screen there's an option to select the keyboard input language, and in that screen my mouse works perfectly fine.
Another thing, i tried to go to the device manager and press uninstall on the mouse&keyboard but it kept refreshing and show them again as if uninstalling did not do a thing.
Also, when i connect the mouse the red light from below(that shows if its connected) is active tho in the keyboard its not(the num lock indicator for example). I tried to run a safe mode(without disconnecting the mouse and keyboard all the way through) without success.
troubleshooter in the settings after i launched windows recognized the problem but did not succeed in finding a solution.
I also hear from time to time the sound of a disconnection(when you remove a cable from a usb port for example, like tananan)
Thanks for anyone who tried to help,and have a good day
