Lenovo Thinkpad Helix DSDT help needed

5 posts in this topic

Recommended Posts

This device is running Mountain Lion nicely, however it needed an external USB dongle for audio and WiFi. At this point I am struggling to patch a DSDT for Battery, SpeedStep, Sleep/Wake, and Display Brightness.


Is anyone else working on this or have worked on another Lenovo machine with a similar original System DSDT? Right now I can't do much with it without plugging it into A/C power for fear of it shutting down without warning, and running the CPU and brightness at unnecessarily power hungry levels.


I've tried looking at patches for these areas of the ACPI on other laptops but have not been able to "port" them or translate their concepts to the Helix's System DSDT. Could really use a hand, and am hoping there's someone out there already working on this that knows more about it than I do.

Thanks I'll check them out, I'm just concerned that because the Helix is an Ultrabook in a Tablet Convertible format that they are going to be wildly different in their makeup. But I guess the only way to know would be to compare.
