UP2 Board doesn't boot

hydroPID26

Hello.
I'm graduated student and use Up2 Board about 10 months.
I did a experiment with the board for conference last week.
it worked well until then.
but today, i plugged DC connector and it doesn't turn on. fan doesn't work. NO blue LED.
no sign of static. don't smell on combustion.
I pushed a power button but no response.
is the board die?
no way make this functional again?

Hello,
I know it will sound a bit silly, but have you tried to verify if do you have voltage at the end of the DC connector? Maybe the power supply if not working properlly anymore.
Thank you !
