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.

The first component that is after the DC Connector its a fuse F14 that is rated for 15A and 24V Max.

If you don`t have voltage in both sides (like 19v Aprox.) change it with a compatible fuse that is rated the same like in the schematic.

If you wanna do a DIY job with wires start with tin wires so you won`t destroy the board just in case of a short.

Q28 is the second component after the fuse. If you got voltage on the fuse and still you can`t power up the notebook check the source,drain and gate on Q28.

If you got no voltage on gate on Q28 check Q31,Q32,Q36 and Q37.
If you got no voltage on gate on Q29 check Q30,Q33 and Q35 and resistor that is on the gate line.

Q28 SI7149DP P-Channel 30-V (D-S) MOSFET  and
Q29 SIS402DN N-Channel 30-V (D-S) MOSFET  that is a stepdown  DC/DC Converter after Q28
