My brother decided to give me his old Razer laptop. He's notoriously shitty at taking care of his possessions but I wasn't about to turn down a $2000 gaming laptop, so I accepted it. However, upon start up, both the trackpad and keyboard didn't work. I plugged an external mouse into the USB port, and both the built-in keyboard and mouse started to work. The problem seems to pop-up after every restart/wake up.
Has anyone come across this before?
