Dead DS415+

[VectraT]

Hi!
Got dead DS415+ whithout power adapter. Tried to power up with mine adapter (from DS416) - nothing, no lights, no fan.
Opened the box - I can see marks of resistor fix, and battery is dead (0.6V). Soldered 100Ohm resistor, replaced battery - still nothing.
Power button has 2.9V and when push, connects it to ground. Any ideas? Some "power on" switch transistor?

Edit: when I connect power to motherboard, "status" led make one flash...
