No guarantee of diagnosis
Browser behavior depends on hardware, firmware, drivers, the operating system, permissions, browser policy, power state, connected accessories, and environmental conditions. A pass or concern does not identify a root cause by itself.
Safe testing
Use safe audio levels. Do not press or strike displays, force connectors, expose batteries, disassemble energized equipment, or perform any action that could cause damage. Stop when you observe swelling, odor, unusual heat, smoke, liquid exposure, electrical damage, or mechanical instability.
