HP 840 G6 - 6050A3022501-MB-A01 - nie uruchamia się

Cześć,

płyta była sprawna u mnie na stole i nagle przestała się uruchamiać. Pobiera 0,028A i tak stoi.

Measure the voltages at the start button in the following cases:
at power off
with power on pressed
at power on.
Measure the voltages on pins 1, 7 of U7400.
Measure the voltages on the gate of Q1300.
Measure the voltages on pins 2, 4, 5, 6, 9 of CN4941.

Pin 3 CN290 ON/OFF
at power off - 5,23v
with power on pressed 0v
at power on. 5,23v
Measure the voltages on pins 1, 7 of U7400.
1- 0v
7 - 1,20v
Measure the voltages on the gate of Q1300.
0v
Measure the voltages on pins 2, 4, 5, 6, 9 of CN4941.
2 - 0v
4 - 3,32v
5 - 0v
6 - 0v
9 - 0v

Measure the voltages on pins 1, 7 of U7400.
7 - 1,20v

You should have 3v.
Measure the voltages on pins 5, 6, 8 of U7400.

Measure the voltages on the gate of Q1300.
0v

Without this voltage, activation of the PCH by the KBC is obtained.
Unfortunately, the KBC does not have accessible pins for measurements.
Measures the resistance to ground on the gate of Q1300.

5 - 5,23v
6 - 3,34v
8 - 1,25v

GATE Q1300 - 0,2 ohm
I took it out KBC from mainboard and nothing changed. Still 0,2ohm. So the problem is with hybrid?

If you have a hybrid problem.

Ok thanks
