The hibernation is not done automatically by the kernel. Instead the kernel reports a charger as a batt= ery. That battery, being a charger, reports a charge of zero. User space monitors this and does as it should if its only known power source is a battery at z= ero charge: it hibernates the system. --=20 You may reply to this email to add a comment.
