I'm currently using this old laptop for basic tasks such as browsing the internet since I'm on the go right now. I brang my own mouse and keyboard with me, but here is where the problem starts. My laptop detects only my keyboard, and not my mouse. I mean, the lights on my mouse activate, but I cannot move the cursor with the mouse I plugged in. I can though use the trackpad on my laptop. I tried with another mouse I had bought for cheap, and yet it still didn't work. Does anyone know the solution to this problem? Thank you.
