I think the T9400 will work, since it seems it won't be limited by your motherboard's motherboard. The SP9400 uses a different socket and thus may not fit. Would you know where I can find detailed specs of your laptop? A cursory search online revealed nothing, and I'll be able to provide more help if I had access to that.

Hey killer, ok the additional information confirms it: the SP9400 won't fit into your laptop motherboard. The T9400, on the other hand, will. May I suggest you double-check with Asus support just to be sure?
