After carefully reading all the posts in this thread, i came to the conclusion that indeed the fault is with the laptops power converter. This wil ONLY affect NC6000s that have a damaged CPU (the ceramic pill of the CPU is damaged). The CPU's still work, but:

Power from the PTU (power translation unit) reaches the top of the ceramic/silicone pill of the CPU by means of the copper CPU heatsink. Users have reported that by pressing down on the CPU fan (right top side of the keyboard) the unit will start up. Initially I attempted to somehow lift the CPU fan so it will not touch the mainboard. It made things worse. Than, i noticed that a part of the heatsink touches DIRECTLY one of the coils and the top of the power connector.

What you need to do is buy some electric insolation tape and wrap it around the copper pipe of the heatsink (WARNING!!! ONLY INSOLATE THE PIPE, NOT THE BASE THAT COMES IN CONTACT WITH THE CPU!!!). Completly wrap the heatpipe with tale, and put some around the end of the heatsink - in such way that the fins of the radiator are not covered, and air still flows trought it. Do not put tape in front or behind the fins, only on top of it, otherwise the CPU will overheat. Also insolate the margins of the metal cpu fan holder, including the borders that come in contact with the copper heatsink, but BE CAREFULL TO ONLY INSOLATE THE MARGINS, NOT THE AIR HOLE AT THE END OF THE FAN, SO AIR WILL STILL BE ABLE TO PASS TROUGHT.

This way, the CPU will be isloated from the PTU, and you will be able to boot up your device normally and also move it around.

Unfortunaly i have no fix for the touchpad yet. I will investigate an if i come to a solution i will let you know.

DO NOT BUY A NEW MAINBOARD, IT IS NOT THE PROBLEM. I have repaird 5 devices by know, an "recovered" two "broken" mainboards. Always, the problem is the CPU coming in contact with the PTU trought the heatpipe.

Thell me if this helps. It worked for me.

razzb3d can you post some pics of this fix?
