Lenovo Edge 15 not detecting SD cards in Ubuntu 16.04

Question

I have a Lenovo Edge 15 (80k9) running Ubuntu 16.04 and kernel 4.4.0-59-generic. I've tried a number of different micro SD Cards (using two different micro-to-SD adapters) and none seem to be recognized by the internal SD reader.

Running blkid only shows /dev/sda* and lines relating to FDE, ditto fdisk -l.

I tried dmesg and searched for lines with "Card", "MMC", and "Reader" but nothing that seemed relevant appeared.
