Hibernation is a power management method for saving data when the battery power drops. If the operating voltage of the batteries falls below a default value, the data of the working memory is saved to the hard disk. In addition, the current state of the operating system with all application programs is also saved to the hard disk in the hibernation file.
The hibernation function can also take place after a preset time has elapsed in which no key input or mouse movement has been made.
In hibernation mode, the device is switched off. In contrast, in standby mode the data is not stored on the hard disk, but in the RAM, and so that this consumes as little power as possible, it is switched to an energy-saving mode. Switching back on from hibernation is associated with reading out the swapped files and data from the hard disk to the working memory.
