I had this problem a lot on a Lenovo X230Table under 14.04 (and maybe the previous distro) but the latest firmware update (BIOS update) from Lenovo seems to have fixed it. I have not yet tried upgrading to 14.10.
(Incidentally, if I'm allowed to say so here, my machine still fails to shut down sometimes: that is, it reboots instead of shutting down, even with the latest BIOS. This can be very bad due to the risk of overheating if it's being put away...) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1324028 Title: [Lenovo ThinkPad X230] e1000e driver intermittently prevents suspend in 3.15.0-2-generic Status in “linux” package in Ubuntu: Confirmed Bug description: utopic has been intermittently failing to suspend for me.
