Hot Switch Power Source and Battery Life about gfxcardstatus HOT 5 CLOSED

Thanks for the report!

Are you absolutely 100% sure there are no apps running in the background that use OpenGL or Core Animation? Nothing in your startup items?

What happens in this scenario?:

• turn off power source-based switching
• make sure no apps are running
• switch to integrated

Does Coconut Battery display the same results? Note that OS X does sometimes get confused for a couple minutes after a GPU switch and doesn't always accurately display the time remaining until a bit later.

You're right!

It was HyperDock. If I disable that and pull out the power cord all is well.

But what's odd is that gfxcardstatus does show "i" in the menu bar even though it must still be using the AMD6750M. Do you "force" the integrated card? Maybe there is some conflict going on and gfx thinks the integrated is being used but it's not. Or HyperDock gets confused and runs out of control (although it doesn't use CPU according to Activity Monitor). Any ideas?

Thanks for your help. BTW, just made a small donation to you. :-) You created an app that probably every dual GPU mac user uses and don't charge for it. That's nice!

Knew it! HyperDock is a really common cause for this since it's not obvious at all.

What's actually going on is a little weird. If you have an application open that is using the discrete GPU, it will continue to do so until it is exited. Even switching to the integrated GPU can't circumvent this problem. So if you've got HyperDock open and it's using the discrete GPU, and then you switch to the integrated one, it does indeed switch cards - but the discrete one stays powered up as well and continues to render things it is being told to render.

Thanks for the donation! :)

OK, makes sense now. So is there a way in gfx to still show what might be holding on to those discrete dependencies even though you're on integrated (i.e., like you do if you're in discrete mode)? That I think would be very helpful to at least alert people - so maybe even make it a red "i" if you are on integrated but something is holding discrete.

Thanks for the quick replies.

Unfortunately there's not right now - it only shows the dependency list when the discrete GPU is active, one way or another. I agree that would be helpful - however, I'm not sure if that information is available or not while you're using the integrated GPU. I'll do some further research.
