in both cases, neither the cpu fan nor the chasis fan work. Any ideas of what's is going on?
Laptop is a compaq evo N1000v

I think you that have two damaged CPU's and probably mainboard now. Unnecessarily also warranty is void. Nevertheless I think there are three parts that could be replaced separately: DC-DC converter, mainboard or CPU. Because your laptop was working with both battery and power supply DC-DC converter
is excluded. CPU also was replaced so mainboard remains.

I tried both processors on a socket 478 m/b and no one works. If I place them back on the laptop, one gives black screen completely and the other, lights up the screen without starting the laptop.
Now I am 100% sure that the replaced cpu is burnt. Actually I put the heatsink on it, but the fan wouldn't start. For 10-15 sec. as I posted earlier I managed to see the compaq boot logo, after that the system shutdown and the replaced cpu never worked again.

It should work just after power on if "fan always on" option is set, othwerwise it doesn't.
Last chance in my opinion is to reset bios by (remove the RTC battery ?CR2032) and try other memory dimm with this CPU which powers on the display.
Anyway, I wouldn't try to repair it by myself. New mobo costs about 500 Euro, am I right?

how?: remove ac adapter and and the battery then hold the power button for 90 seconds then connect only ac adapter and boot it should be ok. if no go try an external monitor to verify that your lcd is ok
