not power, nor led the socket (connector) DC is lit. Removed HD, DVD, memories, battery, was the only motherboard . I want to rewrite the bios but how is budget , if possible, build a recorder BIOS (not have in hand in my workshop, this unit is very important, I also want to pass the budget as soon as possible for the customer)

does not light any LED

Check voltages on power supply connector first.
It has 3 wire: +V, Ground, Adapter ID = 7-19V.

v+ --> 19v
ID --> 16.46v
GNG --> GND


My question is how much is the voltage has to be on top of the transistor PQ47 (P0603BDG). this transistor have the following voltages:
  Gate -> 27.9v
  Drain and source -> 19.5 v

It's ok. if you are confused about gate 28V - see the line +VH28 (28V).
Buy programmer EZP2010 with sockets - cheap and fast.

The defect was solved by changing the bios. Before I was just using the motherboard, memory, processor, and an external monitor. After I recorded the bios and put the flat cable of the LCD screen image back to normal. Topic solved.
