Dear all
someone please help me how to find the ic. for example 13 FG is RT8068A. on schematic and i need to substitute.

I DISCONNECTED PIN1 OF PL605 AND I NOTICED THAT THERE IS NO OUTPUT FROM IC 605 PIN8 VSWH.
THAT MEANS I HAVE TO ORDER AOZ5019QI_QFN23... -
CHECKING THE IC PIN VSWH I GET 10 OHMS TO GROUND. IS THAT NORMAL!Leave a comment:

PL700 IS 9K. WHEN POWER ON I DO HAVE 3.3,5,1.8,1.2,0.6,1.35,0.9 BUT ON PL700 I GET 0.05V
I FOUND A SCHEMATIC AND PL700 HAS TO DO WITH BATTERY WHICH IS NOT CONNECTED SO IT IS CORRECT.
BUT MOTHERBOARD SWITC ON FOR A MINUTE AND THEN SHUTDOWN. NO DISPLAY
IN ORDER TO POWER ON AGAIN I HAVE TO WAIT TO DISCHARGE 2-3 MINUTES AND THEN PLUGIN AGAIN TO POWER ON.
PL605 HAS NO VOLTAGE I WILL SEE THATLast edited by NConstantinou; 08-21-2025, 08:49 AM.Leave a comment:

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