** Description changed: PCIe NVMe drives are very common in new laptops. The Zesty's kernels (including latest 4.10 rc8 from CKT PPA) does not support APST (autonomous power state transitions). A patch does exist : http://lists.infradead.org/pipermail/linux-nvme/2017-February/008051.html https://github.com/damige/linux-nvme It seems that we cannot expect this before kernel 4.11. - Additionally my laptop CPU does never go under PC3 power saving state, - powertop says. I don't know if it's related. + Additionally my laptop CPU does never go under PC3 power saving state, powertop says.
