Latitude E6330

ghorwith said:

Have encountered 2 issues booting a Latitude E6330 (Chimera 2.1 from MB). If booting with only the laptop display, it enters sleep / power saver mode during the boot (power button alternates from dim to bright). Pressing it powers the display and the login screen. System definition is 9,1.

If an external monitor is attached (DVI-D) during the boot process, the external display is the only one recognized by the system. The laptop display is turned off and isn't recognized at all. However, if I boot without the external display cable attached to the dvi-d port, and reattach it after the desktop is displayed, it is recognized, and I can mirror or extend the desktop. I'm guessing it's a problem with a kext but which? Ideas?

Pretty standard Latitude E3660. This is what I can discern with Windows. Can boot in OS X later for more info if you need that.

I have (but the patcher came back with a few warnings and 1 error that I still need to sort out). That may be the issue. I'll get back to you when I get a clean dsdt.aml if it's still an issue.

Have corrected a number of the warnings (although I appreciate these aren't show stoppers), but haven't applied any patch for hd4000. I don't think there's one provided in DSDTSE. What should be patched/inserted? If you need to see my dsdt.aml I can attach it, but if you point me to what needs to be done I can do it too. Tnx.
