I was wondering, if I have an isolated case of a complete failure of my Dell precision 7710.

Today, I simply tried to turn the computer. Nothing.

Ok, I was in battery, plug the AC/DC adapter... nothing. Check the DC output  18.7, a little high, but ok. Use another AC/DC adapter for M6400, same output... nothing. Remove the battery and discharge the possible static in the capacitors... then try with AC/DC adapter only... nothing. Put everything as it was with the adapter and battery... nothing. Change the ram from one slot to other... nothing.

I tried all conventional wisdom for this issues. I just need to fully disassemble the computer and test motherboard components, but I am leaving this for DELL technical support...  Because, I should be in guarantee... The hardware is under less than 4 months new. A real piece of ***.
