Model : Dell Inspiron 15 3000 Series
Board id : Cedar_Intel_MB 13269-1 PWB FX3MC Rev A00

Laptop can't power on. 3v 5v is ok and power key is ok. But can't power on. BIOS flashing can't solve the problems. Need help.

Hello!
Is there any change in power consumption when you press the Power button?
Are there any signs of damage on board (corrosion, liquid residues, burned places etc.)?
Are you using original Dell power supply?
Measure resistance to ground on coils (with disconnected all power sources of course).

Only a little change in power consumption when i press the Power button. Without press power button 0.002 amp and press power button 0.010 amp and drop to normal.
There are no signs of damage on board.
I already tested with Original Dell Adapter and nothing change.
Resistance to ground on all coils are normal. There are no short sign on coils.

Yes. I'm sure. I counted the pins correctly. With press or without press power key, voltages are the same. Laptop are in completely dead position. Only a little change in power consumption when i press the Power button. Without press power button 0.002 amp and press power button 0.010 amp and drop to normal.
