I have several questions for the owners of the CQ40 with AMD CPU and Radeon 3450 discrete graphics.

1. What is the chipset used in this laptop? Is it M780G or is it not? Can someone check it with CPUZ or other similar utility to confirm it?

2. If it's using the M780G chipset, then it should be able to run PowerXpress . Can someone check if it's possible?

3. Can you run Hybrid CrossFire as well?

I think the price for this model is just too attractive, especially with the HD3450 graphics and 250GB HDD. But if the true potential of the PUMA platform, in this case the PowerXpress feature which switches between the IGP and the discrete graphics card, cannot be realized, then I guess it's a lot less charming.

Thank you Shady for the info. Wow, that's kind of disappointing... I thought it would at least be able to run PowerXpress. But according to AMD, the switching happens automatically, mmm. What a shame. What's the point of putting in the HD3450 if it cannot run PowerXpress and Hybrid Crossfire?

Hope there's evidence to the contrary....

Have you tried using the Catalyst driver and the Catalyst Control Panel to see if you can actually run powerxpress or hybrid crossfire?

Do you mean except for those running 32 bit Windows? Or what? Sorry I'm kind of confused.

I'm actually interested in the PDC version of the CQ40 as I'm looking for a budget laptop with better battery life, but the "max 2GB ram" spec on the HP site is bothering me as well.
