If I try to start the laptop the blue power LED on the left edge and the power button LED turn on. The fan is starting, but after a second it stops again. After a few more seconds the LEDs turn off and the Laptop is off again. Display stays black and there is no LED blink code. I also removed the battery and pressed hold the power button down for a while. Then used the power cord. -> Same problem. I suggested a mainboard failure and bought an other one at ebay. But with the new board the problem still exists. Do you have any suggestions?
That would leave the processor ic, usually most motherboards do not include that.

There are two common causes for this and both relate to the power supply.
First is that the connector on the main board is loose or has a bad connection
If you are proficient with a soldering iron this is an easy fix for approx $10

They have some very good step by step guides for replacing power sockets.
It could also be a dying power supply which is the second most common cause.
Replacements are easy to obtain and cost between $20 to $60.
If it is the PSU either get an original replacement (EBAY is best bet) or get one of the many multi laptop PSU's available but if you get the latter please make sure it carries enough or preferably MORE amperage than you need.
The old supply will have the details of both the voltage and current on it and you need to match the voltage exactly and keep the same or better current rating eg 1000 Mw or 1A or whatever it says.
