Have you double checked if this motherboard has cpu lock in correct position , most laptop motherboards has cpu lock which if its not in the correct position it will not post.

Edit. Its usually on the cpu socket.
Below link is for toshiba , but shows what i mean.

From your other post it seems above information also didnt work. Just for information see below link which is a service pdf document for your laptop. Look into page 160 which shows the processor removal and the locking mechanism i was talking about to make sure processor is working ok and the problem is else where.
