N85 No Power (Not Turning On)

Question

I was updating using Nokia Software Updater through PC, and when the program said I had about 2 minutes left, my phone died and went white(the screen). I did not do anything to it as the instructions said. But then it just went dead. and a pop-up message came up in the program that "my phone is disconnected so I had to disconnect/remove usb cable, restart phone, reconnect cord and click Retry".
So I did just that. Trying to power back on, my phone just VIBRATED QUICKLY (just like always when you normally turn back on your phone). But it did not flash anything from the screen. So i tried the hard reset: press Hold Call Button + 3 + * all at the same time while powering up. But still no go.
Please help. Thanks in advance.

Answer 1

Do the PMU reset in the above link.
And/or try Resetting the Logic Board
Resetting the logic board can resolve many system problems. Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1 Unplug the computer.
2 Press the Power On button on the front of the unit.
3 Open the side access panel.
4 Remove the battery from the logic board.
5 Wait at least 10 minutes before replacing the battery.
6 Make sure the battery is installed in the correct +/-
direction.
7 Reassemble the computer and test the unit.
Note:
This procedure resets the computer’s PRAM. Be sure to
check the computer’s time/date and other system parameter settings
