Got a used HP Probook laptop. Just needs a new drive. HP specs say it has an m.2 2280 slot. So that’s what I ordered. Guess I needed to look closer.
edit: Thanks for all the info, guys. Different types of keys are explained here. Gonna have to look for a sketchy no-name brand.
Well incompetentboob, let me tell you. You will short and blow the voltage supply on the motherboard and take that port out of service.
