Thinkpad Edge 420s Memory Upgradation

Hi All

I have a Lenovo Thinkpad Edge 420s (4401) running with 8GB memory;(2*4gb). I need to upgrade the memory to 16gb (2*8gb). Lenovo says this model supports a maximum of 8GB.

Can anyone give some ideas about this whether this model can be upgraded or not.

Also one of the memory module is seated just below the keyboard, what about the other one? Where it is fixed?

Its seen many web sites selling 16 gb memory module kit for the same model. But confused by lenova explanation on the maximum upgrade is possible upto 8gb.

I have not tried it, but I would expect that 2X8GB would work fine.  The second slot is under the motherboard and it requires the motherboard to be removed to get access.
