No Power, All New Parts

[phoenixcomputek7]

I've HAD THIS CUSTOMERS LAPTOP NOW FOR 2 MONTHS AND i CANT GET ANY POWER. (GATEWAY NE SERIES)

I WILL LIST THE THINGS I HAVE DONE THUS FAR.
1. REPLACED DC-JACK
2. REPLACED POWER SWITCH
3. REPLACED RAM
4. REPLACED MOTHERBOARD (2 TIMES)

WHAT THE HECK AM I DOING WRONG HERE, I REPAIR MANY LAPTOPS, INSTALL MANY MOTHERBOARDS, DC JACKS, MEMORY, CPU'S ETC.

I GUESS THE CPU IS BAD, THE THING IS THOUGH I SHOULD BE GETTING THE POWER (RED) LED LIGHT ON THE MOTHERBOARD AFTER THE POWER IS PLUGGED IN, EVEN WITH THE POWER SWITCHED OFF THE LED SHOULD ILLUMINATE WITH THE ADAPTER PLUGGED IN. THERE ARE NO LEDS AT ALL, NO POWER AT ALL, I AM BEGINNING TO THINK THAT THIS LAPTOP IS POSSESSED.

WHAT ELSE CAN I DO OR LOOK FOR? I'VE PRACTICALLY REPLACED THE ENTIRE COMPUTER LESS THE LCD SCREEN.

ANY HELP WOULD BE GREAT.

THANK YOU

The battery or the AC adapter perhaps?

Power adapter is good, tried it on another laptop works fine. Looked up the adapter stats and the adapter is the same as is required by this Gateway NE ( 19V - 3.42)
