Problem is solved.
Capacitor EC3 1000uF Nec tokin was dead. Replaced by 4x330uF tantalum capacitors and problem solved.
I have changed many nec tokin capacitors, but none of them fails with battery only powered.

Samsung NP-R522 power-on problems
Samsung NP-R522 CANNES/BONN CANNES-EXT GFX:AMD
Motherboard powers-on but shutdown almost instant.
If I heat capacitor ec10, (220uF 2.5v) (P1.8V_AUX) then it works.
Capacitor has been replaced with one from a donor board, but problem remains.
Any hint to repair it?

Check VCORE voltage and post readings.
Also check for pulses in bios chip in main bios and backup bios.
