how to switch between gpu's?

hey all my laptop has a internal ati HD3200 and also a dedicated ati HD3650 i went to a systemrequirements site to see weather my pc could run a game, and when it tested it only picked up the intergrated card and failed my pc, how do i switch between the gpu's so the test will read the dedicated card and give a accurate result for me.
thanks (and my specs are in the sig if needed)

 

I have a better idea.... completely ignore systemrequirements.
This is especially true of notebooks.

I don't think I have ever gotten their site to give an "ok" yet and yet games run just fine.

The site isn't just buggy... its downright incorrect pretty much every time.

 

I believe it's automated. On power saver or idle it will use the integrated cards and on full power the 3650. I'm pretty sure that's how it works.

 

haha perhaps you have a good idea there, but it does seem alittle stupid, it would be great to find a site that did a true test, as my pc isnt the most powerful i dont want to risk buying a game that is unplayable, im in a country which doesnt allow for returns, anyway, if it isnt possible so be it.

yes thats correct, but i have it set to full power at all times, and when i hit the catylist control centre it says that the gpu is the dedicated 3650 but using the system requirement sites always comes back as the intergrated 3200, so i thought maybe i hadnt done everything correct.

 

If you want to know if your computer will run a game, post in the "Can my notebook run it?" sticky. This is way more accurate than those crummy websites.
Those are based on inaccurate system requirements, and almost always mis-read(mis-interpret) your system's power.

 

i used the ''can my pc run this game'' thread here and at one other place, and my request wasnt responded to, i dont like to be pushy and was trying to find a means that wouldnt waste others time.
anyway, its not a problem. thanks for the suggestions.

 

....you can switch to a regular 3200.....wow i always knew about that but i NEVER knew the Asus M51 could do that very cool how is battery life on the 3200?
