So when I try to turn my laptop on, something peculiar happens. The usb devices that I have connected to it (microphone, external hdd, etc) turn on, and the keyboard back-lit is on. However, there seems to be no display output, because it doesn't connect to either of my 2 external monitors (Ive checked the monitors and hdmi cables) and the laptop monitor is broken(previous problem) so that doesn't display either. When I try to hold down the power button to manually restart it, everythings turns off for about 5 seconds, then turns back on. I don't know what's happening.
