US 2025/0085757 A1 · INFORMATION HANDLING SYSTEM POWER USE TELEMETRY TO PREDICT SYSTEM STATE OF HEALTH

Abstract

An information handling system monitors current at plural current sensors during each of plural predefined events, such as power up and boot, to detect power anomalies that indicate failing components, such as bad charger, bad power rail, bad motherboard and/or back cover deck. Current during a boot event is compared to a baseline value for the event, such as a value measure and stored at manufacture of the system, and/or an average of current measured for a predetermined number of previous events. In one embodiment, a separate analysis is performed based upon whether the system boots from battery power or external alternating current adapter power.

Dependent claims

An information handling system comprising:

a housing;
a processor coupled to the housing and operable to execute instructions that process information;
a memory coupled to the housing and interfaced with the processor, the memory operable to store the instructions and information;
plural current sensors configured to measure current at plural locations within the housing;
a processing resource interfaced with the current monitor;
and
a non-transitory memory interfaced with the processing resource and storing instructions that when executed on the processing resource:
determine power use associated with the current at each of the plural locations during a predetermined event;
and
compare the power use against a threshold power use for the predetermined event to determine a power anomaly.
