A portable information handling system stores a stylus in a stylus garage having a stylus presence detection so that on removal of the stylus from the garage the information handling system transitions from a low power state to an on state. In one example embodiment, a low power OR gate monitors a pair of contacts of the stylus to initiate power to an embedded controller when one or both contacts separate from the stylus. The embedded controller detects the stylus position, the housing lid position and other factors to determine when to command power up of the system CPU for transition from the low power state to an on state.

A portable information handling system manages power consumption by selectively powering down an integrated display when the housing rotational orientation indicates that visual images have less end user utility, such as between 15 and 80 degrees of open rotation. When the information handling system has a peripheral display interfaced, the central processing unit and graphical processing unit continue to operate to present information as visual images at the peripheral display while the integrated display powers down to reduce power consumption.

Embodiments of the present disclosure provide systems and methods to prevent false triggering of the touchpad buttons associated with a touchpad. The false touchpad button mitigation system and method uses executable logic that upon detection of a button press event, determines whether touchpad data is currently being received from the touchpad, and when no touchpad data is currently being received, inhibit the button press event from being processed by an Information Handling System (HIS). Touchpad data refers to data generated by a touchpad when a user's finger is touching the touchpad. Thus, if the user is not actively touching the touchpad, the false button press event may be blocked by the executable logic.

Systems and methods to mitigate false touchpad button events

A system determines a current state of an information handling system, and receives a sensor output signal. The system determines whether a status change of the sensor output signal relates to an expected state based on the current state and a previous state of the information handling system, and determines whether the sensor output signal is triggered by an external magnet. If the status change of the sensor output signal relates to the expected state and the sensor output signal is not triggered by the external magnet, then the system transitions the information handling system from the current state to the expected state.

State machine-coupled sensor control

An information handling system may detect an event indicating a transition of the information handling system from a first mode to a second mode while the information handling system is in a working state. In response to detecting the event, the system may transition from the first mode to the second mode, disable a human interface device, and switch off a backlight of a display device.
