Me and a few other owners of an edge 520 have an issue with switchable graphics. In our case, the ATI card doesn't work, even with BIOS on switchable graphics. See thread :
I don't know if this is related to your problem. Are you sure that the ATI is active when you set switchable graphics on ? Did you test it on a demanding 3D application ? Do you have switchable graphics as an option in the menu of the power management icon in the icon bar ?
From your experience and ours, it is as if the BIOS settings switchable/integrated have been switched !

Well, I tried BIOS on integrated graphics. First, on startup, it installed a graphics driver and I got a message such as : AMD driver not found (ignored it). Restarted. Now I get a FPS of 85 on Video Card Stability test ! With BIOS on switchable graphics, I got about 20 fps. So, at first sight, the BIOS settings integrated/switchable are simply switched. Look at the other thread for details.
