Can my laptop APU be upgraded?

Hi, I have a hp probook 6475b the specs are:

A6 5350M APU @ 2.9Ghz with 8450g graphics
1x 4gb ram
320gb hdd

I have heard that the apu is upgradeable, I have researched this, and I think I have found that I am able to put a A10 5750M into it?

I am hoping this will give my laptop a decent boost in performance in terms of gaming. As I only use the laptop to play World of Warcraft.

I will also be putting a SSD into it, to better the performance again.

Thanks for any input.

If you have the socket it will fit yes. Cooling and bios support is not guaranteed and depends on the model.
