Questions tagged [hibernate]

Hibernation (ACPI S4 or HTD) is a power-saving mode in which the machine state is written to disk, either a swap partition or swap file, allowing the device to be completely powered off. On resume, the machine state is loaded back into RAM. This allows a faster boot time than a normal power cycle and for the user to resume their session with the applications that were open when hibernate was initiated.
