Tf101 not powering up when plugged in if unplugged does nothing

Ok hopefully someone can help me. My transformer tf101 is not powering on at all. I plug it in, if I listen closely with the back off, I can hear I guess the processor or HD running, but it makes a click and goes silent. Then sound like processor or HD again running after 5 seconds that click and silence again. No lights, or nothing.. If I unplug it, does nothing at all…

Update

Ok so I hooked up my battery out of my good tablet , same thing going on. No video at all, lights at all. Sounds li,e something booting then that click…
