Method for generating reduced snapshot image for booting and computing apparatus

A computing apparatus, comprising:

• a first memory unit;
• a second memory unit;
• and
• a processing unit, for assigning a threshold parameter set for process killing when a specific boot mode is enabled in response to a shutdown request, wherein when the first memory unit of the computing apparatus has at least one process satisfying a process killing condition, the processing unit kills the at least one process satisfying the process killing condition, wherein the process killing condition includes a criterion based on the assigned threshold parameter set;
• wherein the processing unit, in response to the shutdown request, enables the computing apparatus to enter a hibernation state;
• and before the computing apparatus enters the hibernation state, the processing unit generates a snapshot image for booting and stores the snapshot image to the second memory unit, and the snapshot image includes at least one process reserved in the first memory unit after the processing unit kills the at least one process satisfying the process killing condition.
