  1. Thanks for the help! I'll give this a try tonight and let you know how it turns out.
  2. Greetings. My first post. First of all, let me apologize for being a complete noob. I have been able to install Mountain Lion on my M3800 and so far have most everything working except for sleep mode. When I try to go to "sleep", the screen goes white with a small square where the mouse pointer is and that's it. The fans and drives are still running. I can exit this mode by pressing the mouse button. I've been reading a lot and trying just about everything. I tried an updated sleepenabler.kext for ML but it just causes a kernel panic. The very limited BIOS is set to S3 mode. All sorts of different boot flags don't change anything. What I have now is a patched DSDT that I created by extracting the existing DSDT and patching it with a file that is on Mald0n's site for the M5800 motherboard (same as M3800). I removed nullcpupower.kext and sleepenabler.kext. Even after all this "sleep" mode still the same as before. I've played around with this for a while and it's possible that in all my fumbling I might have missed something. I'd like to start from square-one on this sleep problem and do this methodically. Any ideas? Thanks. Walker Acer Aspire M3800 Dual core Pentium E5200 4 gb DDR Intel G43 xpress chipset.
