BASIC CHECKS:

KB9012QF KBC Controller
on pins:
100 – EC_RSMRST#
check +3VALW_EC on LE1 coil. Its always voltage for KBC controller.
Pins: 3, 22, 33, 96, 111, 125.

Main Power – Charger
PU100 – ISL88731CHRTZ

Check:
Pin2 – ACIN
AC Adapter Detection Input. Connect to a resistor divider from the AC adapter output.

Pin13 – ACOK
AC Detect Output. This open drain output is high impedance
when ACIN is greater than 3.2V. The ACOK output remains low
when the ISL88731 is powered down.

Pin3 – VREF 
VREF is a reference output pin. It is internally compensated.

Pin23 – VDDP
Linear Regulator Output. VDDP is the output of the 5.2V linear regulator supplied from DCIN.

Critical check

RSMRST# must drop if power button its press

+5V/+3V RT8206B

 

ALWAYS VOTAGE

PL21 +3.3V_ALWP

PL20 +5V_ALWP

 

+VGACORE RT8208 1.8V

CHECK PL22 for GPU VOLTAGE

 

OZ8681 PU9 Charger IC

Check DCIN PIN 1 (must be 19v)

If not check PQ24 FDMC4435BZ and all the diodes aside connected to ground.

If all the voltage its present go to HP website and take the BIOS file and reflash the BIOS IC.
