We sell our Intel chipsets and processors to third party manufacturers and they design their own computers with their own features, settings, and capabilities. I notice according to your laptop model your manufacturer disable Intel’s Graphics that is why you are getting this message, "this computer does not meet the minimum requirements for installing the software”.
I recommend you to download from Sony* the proper driver according to your OS:
Since ATI Mobility Radeon HD 5470 card is AMD, in case you want to get the generic driver I recommend you to contact them for the driver.
Hope this helps you
