DELL INSPIRON P66F BLINKING AMBER 3 TIMES AND WHITE LIGHT 5 TIMES

[NConstantinou]

I REMOVED INTERNAL BATTERIES AND I SUBSTITUTE RAM BUT STILL THE SAME.
WHEN I PLUGIN CHAGER I DO HAVE 3.3,5 AND 1.8 V. AND ON PL700 I GET 0.27V.
BIIOS PINS 7,8 I HAVE 3.3V
IS THE PROBLEM ON MOTHERBOARD OR BIOS.

I WOULD LIKE TO MENTION THAT I FLASH BIOS AND NOW FAN SPINS BUT NOTHING ON SCREEN AND STILL THE SAME WITH FLASH LIGHTS

Which motherboard? LA-802P?

Remove all power. Meter in resistance mode. Measure the resistance to ground of PL700. What is the resistance in ohms?
