Problems solved by technology

[0003] However, the power problem of personal digital assistants has always been a fatal wound. Although the current personal digital assistants do not have hard drives, optical drives, and display screens are smaller than those of notebook computers, the power consumption is better than that of notebook computers. Many, but when the notebook computer is turned off, the power of the whole machine is turned off, and the operation of the whole machine will only start when the power is turned on next time, but when the personal digital assistant is turned on, pressing the power button does not turn off the whole machine. The power of the machine is completely turned off, but only the power of the screen is turned off, and part of the power is provided to maintain the data in the memory in operation. More power-saving will reduce the operating frequency of the central processing unit (CPU, Central Processing Unit). Reduce the power consumption rate, but despite this, if it is not used at all, it will still completely lose power for the system for a period of 10 days and a half months. Memory) data will disappear, which will cause great inconvenience to infrequent users

Embodiment Construction

[0021] Please refer to Fig. 1, this is the system structural diagram of the present invention, has included following parts:

[0022] The setting module 190 is used to receive the time threshold input by the user and the setting of the standby mode activation, which may include well-known keyboards, joysticks, buttons, remote controllers, or touch screens, etc. for the user to operate. The input device is used to receive the setting value selected and input by the user, for example: select which standby mode to set through the setting menu, and input the set time threshold according to various standby modes.

[0023] The system parameter table 180 is used to record the time thresholds of various standby modes, and information records when the system enters the deep standby mode 240; once the system enters the deep standby mode 240, the working information in the random access memory 120 will be lost due to Therefore, the time threshold set by the user must be recorded. The BIO...

Abstract

An power-saving method of personal digital assistant includes operating system to enter into deep standby module by power-saving monitoring module and compressing operation data in RAM to be memory image file being stored into NVRAM, storing said file into external storage unit if storage space of NVRAM is not enough and interrupting power supply of personal digital assistant completely when storing operation is finished.

Description

【Technical field】 [0001] The invention is a power saving method of a personal digital assistant, especially a method for maintaining the working data in the random access memory after the power of the whole system is turned off so as to achieve the power saving effect. 【Background technique】 [0002] Personal Digital Assistant (PDA, Personal Digital Assistant) is small in size, can be used regardless of time and place, and can be started quickly. Its functions can range from simple personal notebooks to complex application software, such as accounting, Internet access, and satellite navigation. , Notes, stock market quotes, multimedia and other functions, all of which fully demonstrate the style of digital assistants. Among them, the lightness and smallness are the important features of personal digital assistants. Currently, the weight of personal digital assistants on the market is about 150 grams. They can be put directly in the pocket and used wherever they go, which is ...
