More than likely, you will not be able to replace it. Laptops are not known for their upgradeability. There are some that can be upgraded, but I don't think yours is one of them. Sorry.
Seeing as it is from a known manufacturer then it is more than likely that you can't. Normally they actually solder the parts onto the board. If it was from one of those customisable companies that simply ship generic cases with requested parts then it is a lot more likely that something could be changed
