Hi, I have an old acer 5515 laptop and i want to install an am2+ proc and is it possible to add cpu microcode?

I have successfully moded it before installing a dual core am2 athlon but i have to do a water cooling Frankenstein style  

now i got a spare am2+ athlon from a dead pc so i want to use it in the acer but it just heats up no boot.

what are the steps to do it? can it be done?
