Hi again, > Recently my rather old HP Elitebook 2540p with an SSD in the upgrade > bay running Fedora 27 stopped booting when not plugged on. > The laptop is equipped with an 1st gen Intel Core i5 540M processor > as well as an "Intel Corporation 5 Series" SATA controller (lspci > output attached). The more I analyze this issue, the more I think it is caused by ALPM (agressive link power management). When I switched in BIOS the SATA mode from AHCI -> IDE everthing worked like before, so does the laptop when I am connected to wall power. However I wonder, did ALPM enablement accidently slip into stable Fedora-27 updates? I thought ALPM was targeted for Fedora-28: https://www.phoronix.com/scan.php?page=news_item&px=Rawhide-Flips-On-SATA-Med-Power Best regards, Clemens _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
