Hand held apparatus having sleep function and operating method thereof

Abstract

The hand-held apparatus having dormancy function comprises a dormancy triggering module for receiving a dormancy signal, a dormancy mark, a non-volatile memory and a processing module, wherein the processing module responds the dormancy signal and switches the hand-held device to privileged mode, the system information of hand-held apparatus is stored to the non-volatile memory, while the dormancy mark is labeled as a first value, and a power supply circuit is triggered to shut down the hand-held apparatus.

Description

technical field [0001] The present invention relates to a handheld device (Handheld Device) with sleep function and its operating method, and particularly relates to a method of transferring system information of the handheld device by triggering the hardware abstraction layer (Hardware Abstraction Layer, HAL) of the handheld device. The hand-held device and its operating method are stored in a non-volatile memory, thereby causing the hand-held device to enter a dormant state, so as to actually achieve the purpose of saving power. Background technique [0002] With the popularization of mobile communication, handheld devices, such as handheld computers (Handheld PC), personal digital assistants (Personal Digital Assistant, PDA), etc., have become one of the necessities in most people's lives. For existing handheld devices, when the user presses the on / off button on the handheld device, the screen of the handheld device will be turned off, and when the user presses the on / off...

AI Technical Summary

Problems solved by technology

The first way is to add a backup battery (Backup Battery) to the handheld device. However, this solution only delays the time of data loss. Similarly, once the backup battery is exhausted, the handheld device will be damaged due to The same reason makes the system power interruption and causes data loss

The second method is to add a hold key (Hold Key) to the handheld device. The user can completely cut off the battery of the handheld device by pressing the hold key to save power, but this will also cause data loss.

[0005] The third way is to provide a backup / restore (Backup / Restore) application program (Application Software) in the handheld device. Through this application program, the system can back up user-related data, but its operation is quite cumbersome , Inconvenient to use, and users need to purchase additional memory cards, increasing user costs

In addition, when the user wants to save back and turn it on, the handheld device cannot be directly restored to the operating state before it was turned off, and the user must re-operate the relevant application program to continue the relevant operation
