I ran into the same issues after testing. I had to uninstall my video drivers, and while running standard VGA (I raw installed Windows), I installed one of the stock BIOS and reset defaults on that. Then after the OS loaded, I installed the Cat 12.1's again, and the hybrid mode worked again. *edit* See below for an easier way the reinstalling drivers. **
I then reloaded the mod BIOS and only changed the VIDEO settings.
To set true Power Xpress mode:
Set "Power Xpress" then:
PX Fix Mode: Enable
PX Dynamic Mode: Disable
Stereo 3D: Disable
PX mode: MuxLess
Discrete GFX Modules: None
HDMI Audio: Enable
To set the original Hybrid mode:
PX Fix Mode: Disable
PX Dynamic Mode: Enable
Stereo 3D: Disable
PX mode: MuxLess
Discrete GFX Modules: None
HDMI Audio: Enable
To set switchable + Hybid (HOLY GRAIL MODE, BUGGY!!!):
PX Fix Mode: Enable
PX Dynamic Mode: Enable
Stereo 3D: Disable
PX mode: MuxLess
Discrete GFX Modules: None
HDMI Audio: Enable
The great part about setting true Power Xpress for me is, I am one of those users with the BSOD issue. Now I can at least fall back on the discrete only card (I got to really test it to see if the BSOD issue goes away). *edit* I give up, I'm sending this thing back. Software patch on HP's site didn't do anything for me!**
I wish I could flash the Video BIOS back to stock but cannot. One user I found reported that after installing F. 21, the BSOD's stated (no clue what they were running before). I tired to flash the F. 1D BIOS to see if that would fix my problem, but the Video BIOS still stays dated 2011/04/06. I don't believe the F. 1D BIOS has Video BIOS code (would need a confirm on this).
Anyway, to if you mess up and turn on switchable graphics, but leave the card using the higher powered card, you will run into ColdRush's issue.
ColdRush, to fix the problem...
First, set Hybrid or PowerXpress mode as I outlined above. Open Device manager and select the card that has an arrow pointing down, right click select properties, then enable the device. Restart. Should work okay now. If you change video settings in the future, manually set the device to Power Saving!
Word of warning, DO NOT SWITCH GRAPHICS MODES WITH HDMI DEVICE. Unplug the HDMI device first! You will be sorry if you do. lol
