Hi!

I'm working on a hp laptop, which doesn't turn on, if it is, it shuts down unexpectedly.

Right now it doesn't have 3.3V or 5v as i measured.

I can not find a schematic to its board.

The number i found on it:
DA0R76MB6D0 Rev: D

under the RAM Dimms: Model R76

On a russsian site i found pics of the board with the same problem, but i'm not sure if i understand the instructions correctly there.

They found out that the power regulators are defective and gave the type's of them: NB669 and NB670

I measured the shown items and input 19.5V but can not find output.
And i would like make sure they are the exact components.

i hope You can give advices and tips on how to.
A schematic also would be fine.
Thanks for all.
