Display apparatus and operating method thereof

An operation method of a display apparatus, the operation method comprising:

• receiving a power-off input for the display apparatus;
• in response to receiving the power-off input, obtain information on a system status of the display apparatus;
• determining whether the system status of the display apparatus is identified as unstable, wherein a malfunctioning of a system driver, application, or memory indicates an unstable system or a requirement for a reboot for a software update indicates the unstable system;
• and
• in response to the system status of the display apparatus being identified as unstable:
• storing, in nonvolatile memory, execution status information of the application currently being executed in volatile memory;
• performing a rebooting operation after storing the execution status information in the nonvolatile memory;
• and
• entering a suspend-to-RAM mode after performing the rebooting operation by:
• storing, in the volatile memory, execution data regarding the application which is obtained by executing the application by using application execution status information stored in the nonvolatile memory, and
• maintaining a power supply to the volatile memory.

A non-transitory computer-readable recording medium having stored therein a program for performing an operation method of a display apparatus, the operation method comprising:

• receiving a power-off input for the display apparatus;
• in response to receiving the power-off input, obtaining information on a system status of the display apparatus;
• determine whether the system status of the display apparatus is identified as unstable, wherein a malfunctioning of a system driver, application, or memory indicates an unstable system or a requirement for a reboot for a software update indicates the unstable system;
• and
• in response to the system status of the display apparatus being identified as unstable:
• storing, in nonvolatile memory, execution status information of the application currently being executed in volatile memory;
• performing a rebooting operation after storing the execution status information in the nonvolatile memory;
• and
• entering a suspend-to-RAM mode after performing the rebooting operation by:
• storing, in the volatile memory, execution data regarding the application which is obtained by executing the application by using application execution status information stored in the nonvolatile memory, and
