I have provided the explanation as to why the i7-840QM won't work.

 

It has nothing to do with the processor being discontinued.

 

All of the processors in that manual have been discontinued.

 

Also, if your notebook only has the onboard Intel graphics, no quad core processor would work because they all require a discrete GPU such as one of the AMD models listed in the service manual.

 

Only the 1st gen dual core processors support the onboard Intel graphics.

Like I wrote earlier, different motherboard part numbers are used for the models with the dual core processors.

 

Since your notebook came with a dual core processor it has the dual core motherboard, not the quad core one.

 

There is no way you will be able to get the quad core to work in your notebook.

 

It is certainly not worth replacing the motherboard with one that supports the quad cores.
