If none of the usb ports are recognizing anything you hook up to them then that means the motherboard is bad. Easiest way to know, hook up a usb mouse or usb keyboard, those it should detect and install.
If it can't do that then you know for sure the motherboard is bad. If it does detect the keyboard and mouse then you know its the other devices that your hooking up that are faulty.
Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.
Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.
