Razer Blade 15 Won't Turn On

My Razer Blade 15 laptop unexpectedly shut down all of a sudden this morning (no Windows shutdown notification, no error message, it just abruptly turned completely off). Now it won't turn back on. I disconnected every external peripheral, disconnected and reconnected the AC adapter, but I'm getting nothing holding the power button down for over 10 seconds. It's past the limited warranty - what are my options? The official site told me to look for support here...
