Hardware details
= Issues = (see this link for more information) working
 * If the device has an UEFI Firmware version >1.61 it will not resume from suspend
 * Sometimes, when the device resumes from suspend, the power LED will blink
 * Sometimes, when the device resumes from suspend, the hotkeys are no longer

= Workarounds = When the device resumes from suspend, the Wifi will no longer work. This seems to be a problem with wpa_supplicant, because restarting it fixes it. On Ubuntu distributions, this problem does not occur, so they have a fix for it. See this Ubuntu bug report for more information: https://bugs.launchpad.net/ubuntu/+source/gnome-nettool/+bug/1311257.
