Hey all, recently been trying to get Mojave up and running on my e6230 following this guide, using this bootpack and using this DSDT file (which fixed my sleep on lid close problems). I'm happy that most everything is working so far (besides the battery indicator seeming inaccurate although I haven't had time to fully test it yet), except for one problem -- I can't change the screen brightness at all, with the option missing altogether from System Preferences > Displays. I've attached my debug report to this post, hopefully it'll help you guys out. Thanks a bunch in advance. debug_24781.zip
Hi, i just managed to install Yosemite on my T410. I have full QE/CI and everything is working well except sleep: The T410 goes to sleep but wakes up without backlight. I tried a few different dsdt files I found for the T410 but none of them fixed the sleep problem. Adding darkwake=0 to the org.chameleon.Boot.plist did not help too ... Did anyone of you have working sleep with the T410 on OS X Yosemite? Any help would be amazing! Thanks a lot, Barki
Hey guys. Any help at all on this would be greatly appreciated!!! I've been working pretty solidly on getting my x201 fully operational. Everything works sleep related. Beeps when going into sleep just like windows. (I think that's called ACPI sleep) And wakes just fine. EXCEPT the backlight stays off when waking back up. I was looking at the IOReg output before and after sleep and noticed a difference. (Below) Before Sleep, The IOPowerManagement for AppleBacklightDisplay only has 2 power states... Current and Max. After sleep, that same device has 3 power states. Current and Max like before. But now it has a DevicePowerState. What is happening here? And could this be the issue with the backlight not coming back on? Attaching the DSDT.aml from my system. dsdt.aml.zip
