Configuration Details

Had to do DSDT override and use Setup 1.30 witih 56.25GB/36-bit compaction to have the card detected. On my X220 it is still plug and play from a cold boot with no DSDT/Setup 1.30 needed, that was after Lenovo tweaked the BIOS to do a dynamic TOLUD adjustment when detecting EC plugged in. Seems that this feature is absent in the L440.

I will provide some more tests with an external LCD and also comparisons with a X220 and (hopefully) a T540p.
