pin28, BLON_OUT_C =3.10V
pin1,4 DCBAT_LCD=13.11V

+LCDVDD, LCD_BRIGHTNESS, BLON_OUT_C,DCBAT_LCD-These are responsible for backlit issues

General-purpose input/output (GPIO)

Hold down the "D" key, push the power button, release the power button, wait 2-3 seconds and release the "D" key
The laptop should go through an LCD test of solid White, Red, Green, Blue and Black 2 or 3 times.
After completion it should try to automatically boot 2 or 3 times.

Steps to Identify the MOSFET Type  ===============================
Multimeter (with diode test function)
Knowledge of the circuit layout

Locate the MOSFET: Find the MOSFET in the circuit. It will typically have three terminals: Gate (G), Drain (D), and Source (S).
Use the Multimeter:
- Set the Multimeter to Diode Mode: This mode allows you to test the forward voltage drop of the diode junctions.
- Test the Gate-Source Junction: Connect the positive lead of the multimeter to the Gate terminal and the negative lead to the Source terminal:
If you see a reading (typically around 0.6V to 0.7V), it indicates a P-channel MOSFET.
If there is no reading, reverse the leads (positive to Source and negative to Gate). If you get a reading now, it indicates an N-channel MOSFET.
Test the Drain-Source Junction: Next, test the Drain-Source junction:
For a P-channel MOSFET, connect the positive lead to the Drain and the negative to the Source. You should see a reading.
For an N-channel MOSFET, connect the positive lead to the Source and the negative to the Drain. A reading indicates an N-channel MOSFET.
Confirm the Findings: Based on the readings from the Gate-Source and Drain-Source tests, you should be able to identify the type of MOSFET:
- P-channel: Positive voltage on the Gate relative to Source turns it off, and the Drain-Source junction will show conduction when the Source is more negative than the Drain.
- N-channel: Positive voltage on the Gate relative to Source turns it on, and the Drain-Source junction will show conduction when the Drain is more positive than the Source.
Additional Tips

Check the Datasheet: If you can access the part number on the MOSFET, look up the datasheet for definitive information about its type.
Visual Inspection: Some MOSFET packages may have markings indicating their type.
By following these steps, you should be able to identify whether the MOSFET is P-channel or N-channel while it is still in the circuit
