ProBook 4720s switchable graphics?

Hi,

So, I have recently bought HP ProBook 4720s laptop with ATI HD6370 GPU and i-3 380M CPU.

Since there are GPU built in the i-3 CPU, is there any chance of making it switchable, like it is in G series HP notebooks?

I didnt find any options nor in BIOS, neither in HP driver page and specifications.

I have seen G series have switchable graphics - Intel HD and ATI HD5470. Since HD6370 is upgraded version of HD6370 (according to notebookcheck), there should be a way of making it switchable - to save some battery power and in case HD6370 passes out.

Any suggestions? Maybe there are some compatible BIOS updates or something? Or just a piece of software like it is with the G series?
