Dell precision 7760 stopped working and taking charge?

It just randomly turned off, the led light doesn't come on when I put the charger in, when I press the power button an amber light shows but only stays for the duration that I am holding the power button, if I hold the button for 5 seconds an amber light will be on for 5 seconds then disappear as I release. Can someone help me please!? I have it plugged in right now and there's no lights. I unplugged everything, took the battery out, hold the power for 30 seconds and nothing changed, I even tried powering on with battery out and charger in and still got the same orange light
