Without knowing which version of BIOS you are running I will suggest updating it before moving forward. Just to be safe.

That model does support the 540m. If you are buying from ebay make sure that it has some type of return option! Also pick up some decent thermal compound to apply to new CPU. As long as you feel comfortable taking the laptop apart go for it man! Will be a nice upgrade from an i3.

CQ62s are a pretty easy teardown/rebuild. Should be an easy task if you have patience. Just be VERY VERY VERY careful with the ribbon cables and connections on the motherboard. Here is a teardown vid (do not use a power tool pls):

Good Luck!
