Managing power states of an IHS, including: identifying, at a first time, an output of a first sensor, a first output of a second sensor, and a second output of the second sensor, the first sensor and the second sensor detecting a presence of one or more magnetic fields; determining, based on the output of the first, second, and the third sensors, that a power state of the information handling system as a working power state, and in response, and at a second time after the first time: determining that the first output of the second sensor changed from a first state to a second state; determining that the output of the first sensor is in the second state; and in response to determining that the output of the first sensor is in the second state, adjusting the power state of the IHS to a low-power state.

Managing power states of an information handling system

System boot-up can be enabled in low temperature environments. A laptop or other battery-powered computing device can include multiple batteries and a battery architecture that allows the multiple batteries to simultaneously discharge to thereby provide adequate power to boot the system in low temperature environments. The battery architecture may also allow a battery with a higher relative state of charge to charge another battery with a lower relative state of charge to thereby equalize the batteries' relative states of charge.

Enabling system boot-up in low temperature environments

An information handling system implemented as a convertible notebook may include a first assembly, a second assembly hingedly coupled to the first assembly, a magnet housed in the first assembly, a giant magnetoresistance sensor housed in the second assembly, a Hall effect sensor housed in the second assembly, and a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.

Systems and methods for avoiding undesired power on when information handling systems are stacked

In one embodiment, a method for preventing an operable state in a plurality of components of an information handling system in response to a reset of a power supply includes: receiving, by an embedded controller of the information handling system, power from the power supply after the reset of the power supply; causing a platform controller hub of the information handling system to receive the power from the power supply; receiving a signal from the platform controller hub indicating that the plurality of components should be placed in the operable state from an inoperable state; determining that the reset of the power supply was caused by the power supply being previously removed from the information handling system; determining that a position of a lid of the information handling system is in a closed position; and causing the plurality of components to remain in the inoperable state.
