After successfully getting the D8xx series laptops to work nearly flawlessly, I have moved to an E6520. I currently have 10.7.3 running pretty decently on it and it's been performing well for over a week now. I used some of the kexts and other fixes designed for the E6420 series to get it going. I finally got shutdown and restart to work using a DSDT designed for another E6xxx series. So here's what I have:
Working: Ethernet, Graphics 1920x1080 including mirroring, all USB ports, web cam, Audio, VGA, Port Replicator (partial), shutdown, restart.
Not Working: Intel wifi (to be expected), sleep, DVI port on port replicator (DVI works fine on the D8xx series replicator), SDHC (card reader), audio from the port replicator.
Tried all the SDHC kexts to no avail but reading SD cards is no high priority to me. I'm hoping to somehow get DVI working on the port replicator and most importantly, sleep. Executing sleep simply locks up the device. Also, when I close the lid when the device is attached to a port replicator, the screen stays on.
Anyone out there mess with the E6520, and if so, what were your experiences like and what do you have working?
Specs from "About this Mac":
Processor 2.49 GHz Intel Core i5
Memory 8 GB 1333 MHz DDR3
Graphics NVIDIA Quadro NVS 4200M 1024 MB
Software Mac OS X Lion 10.7.3 (11D50b)
Do you have a DSDT or VERBATIM instructions on how you got this working. I've been on this a week and getting nowhere. Please help with your wisdom.......Thanks
