Display stays black after waking from sleep - Dell Precision M60

[nigelbb]

I have my Dell Precision M60 (Pentium M 1.7GHz, Nvidia Quadro FX Go700 graphics) laptop working almost perfectly under OSX86. The one irritating problem that I cannot fix is that after sleep the display does not wake up but remains black. The system wakes OK apart from that as confirmed by connecting using VNC or ssh. I have tried various graphics injectors (NVinject, Titan, Natit etc) but none fixed the problem. Another probably related problem is that occasionally (perhaps 1 in 10 times) when the system is booted that the screen stays black & has to be powered off to restart. Conversely very, very occasionally the display _does_ work after waking from sleep.

 

Has anyone any ideas?

Hi, I have the same laptop and tried tiger/leopard on it a while ago.

 

I had two problems with it:

 

- wake from sleep does not work

- machine gets very hot, powermanagement issue

 

 

Got the second issue almost fixed with i8k but too messy.

Maybe you can try openhaltrestart.kext from Psystar for the wake fro sleep problem (or Superhai's cpu power management driver).

I have a Dell E1705 with 10.5.6 and using NVInjectGo v0.20 and I have the same issue. I had to turn off black display in PM to avoid the problem. A trick you can do is once display is black hit the Power Button, then press S. It will put machine to sleep. Then press the Powerbutton to wake, then the display will come back. I wish I can get this issue fixed...
