What are you trying to say? The sentence is incomplete. Is it overheating, or shuts down? Need more info.

Have tried different AC adapter?

What you are looking for is called the "Service Manual" (as opposed to the normal manual). Acer doesn't give out these to non-technicians, but if you do a couple searches on TPB you'll find a very handy torrent with pretty much every manual you could ask for (and it does have the Aspire 4520 manual, I checked).

Without the manual at hand though, I can tell that all you need to do to get to the processor is open up the back and then move the heatsink arm connecting the processor to the fan (I did it recently).
