Examples are described herein for monitoring power source usage of a computing device, including a battery and another power source, over time. In various examples, time periods of this monitored time may be added to a time count based on their immediately previous or immediately subsequent time periods satisfying a condition. The time count may be used to track periods of time during which certain power source usage factors are present that may lead to or may indicate the presence of battery swelling. After a time period is added to the time count, the updated time count can be compared to a time count threshold, and a user of the computing device may be warned based on the comparison. The threshold and warning may be selected to warn a user of potential present or future swelling of the battery.

Detect and prevent battery swelling

An example of a computer-readable medium to store machine-readable instructions. The instructions may cause a processor to update a machine learning model based on first confidential data set. The machine learning model may have been previously trained based on a training data set distinct from the confidential data set. The instructions may cause the processor to apply the machine learning model after the update to a second confidential data set.

Updates of machine learning models based on confidential data

An example of a computer-readable medium storing machine-readable instructions. The instructions may cause the processor to receive thermal data for a device and apply anomaly models to the thermal data to produce grades. Grades for a device may be combined into a system thermal grade and corrective actions identified to improve the system thermal grade.

Receiving thermal data and producing system thermal grades

An example of a server including a communication interface to receive telemetry data from a plurality of client devices. The telemetry data is to indicate a health of a client device from the plurality of client devices. The server further includes a prediction engine to process the telemetry data to determine the health of the client device with a prediction model to identify a hardware issue at the client device. The server also includes a diagnostic evaluator in communication with the prediction engine. The diagnostic evaluator is to request a local confirmation of the hardware issue from the client device upon identification of the hardware issue by the prediction engine. The local confirmation is determined at the client device via a diagnostic engine. The server also includes a reporter to report the hardware issue upon receipt of the local confirmation.

Hardware replacement predictions verified by local diagnostics

A system may comprise a database to collect telemetry data corresponding to a particular component of a device. The system may further comprise a controller coupled to the database. The controller may receive telemetry data for the particular component from the database. The controller may further determine a plurality of metrics for the particular component based on the telemetry data, wherein the plurality of metrics is determined for a plurality of suppliers and select a particular supplier of the plurality of suppliers based on the determined plurality of metrics.

Supplier selection

In some examples, a computing device can determine a data state from telemetry data received from a plurality of client devices, determine a state change using the data state determined from the telemetry data, determine, using the state change, a potential cause of a fault of a component of a client device of the plurality of client devices, where the potential cause of the fault is determined in response to receiving a support inquiry from the client device, and display a timeline of state changes, where the timeline includes the determined state change of the client device.
