Surface Pro (1st Gen) Does Not Turn On

I cannot get the Windows Surface Pro to turn on.  It did yesterday once for 3 seconds but it turned back off.  I have had it plugged in overnight but still cannot get the unit to turn on.  I have held down the button for 30 Seconds.  I have held down the volume and power for 30 seconds.

I'm not sure how it should act, but when I plug in the power connector, the light flashes, then turns solid (it stays white).  Suggestions?

Thank you for your suggestions.  I'm going to disassemble it and test the battery.  I will post when I get a chance.
I have disassembled the Surface Pro.  If you haven't guessed already, it's NOT fun.  I did do it successfully as far as I know without busting anything.  I tested the battery with a  multi-meter.  It's supposed to be a 7.4V battery, but it tests at 5.7V.  Now I don't know if that's because the battery is bad or the motherboard is not charging the battery, but I ordered a new battery in, so we will see what happens.
UPDATE!  The battery came in and I CAN get the tablet to turn on!  HOWEVER, even though the battery shows as charging when I plug in the AC adapter, the percentage was going down!  I have ordered an AD adapter in the hopes that the charger just doesn't put out enough current.  Otherwise I fear it is the motherboard.  I will keep you updated.

The AC Adapter was putting out power, but not enough to charge the internal battery.  A replacement charger repaired this issue.
