Diagnose a computer that abruptly loses power during use by checking whether the event is thermal, battery-related, charger-related, external-power-related, or another hardware protection problem.
Diagnose performance that falls as a computer heats up by correlating temperature, clock or performance behavior, workload, airflow, fan operation, and recovery after cooling instead of assuming every warm computer is throttling.
Explain when dust can reduce computer performance by restricting airflow and causing heat-related throttling, while separating cooling-related slowdown from unrelated Windows, storage, memory, or software problems.
Confirm or rule out computer overheating by combining temperature readings with workload, fan behavior, throttling, instability, shutdown patterns, and airflow checks rather than relying on one universal temperature cutoff.
Diagnose a laptop that feels excessively hot by separating expected heat under heavy use from abnormal idle heat, blocked airflow, sustained background load, cooling-system problems, and battery safety issues.
Diagnose a laptop fan that runs most or all of the time by checking current workload, heat, airflow, charging or performance modes, dust, and fan condition before assuming the fan itself is defective.
