Abstract

A portable computer and a method of controlling a power saving mode of the portable computer, in which an embedded controller directly turns off system power without system wake up operation in a process of turning off the system power or switching a power saving mode when battery power is decreased. The computer includes a control unit for notifying whether a power saving mode is a hybrid sleep mode when the portable computer enters the power saving mode; and an embedded controller for detecting whether the remaining amount of a battery decreases below a threshold value or a predetermined period of time has passed after the computer enters the power saving mode to perform hibernation or turn off system power, if the power saving mode notified from the control unit is the hybrid sleep mode.

Description

technical field

[0001] The present invention relates to a portable computer and a method of controlling the power saving mode of the portable computer. In the present invention, the embedded controller will directly shut down the system power, so there is no need to wake up the system during the shutdown process, or switch when the battery power is reduced. It is a power-saving mode, and there is no need to wake up the system at this time. Background technique

[0002] Although different operating systems support different power-saving modes in laptops, in most cases, laptop power-saving modes typically consist of S3 (Suspend to Random Access Memory (RAM): Standby mode) and Power management at the S4 (Suspend to Hard Disk: Maximum Power Saving Mode or Hibernation) levels, which are defined through the Advanced Configuration and Power Interface (ACPI).

[0003] The S3 level is a power saving mode that continuously supplies power to the random access memory (the main memory o...
