Hi 

 I have a problem with my laptop fan which cause it not to start and throwing the "Fan Error" during boot.

 the fan socket has 5 wires, could you help me know the pin out diagram to check weather or not the fan is getting a signal from the motherboard ?

I don't have a similar machine so I cannot be sure, but most of the models' fans really only have 3 wires, even if there are more positions on the plug.  The wires are normally positive, ground and one for a tach pulse, used to count revolutions.  Usually, the ground is white and the positive is red or black.
