How testing tools help

Testing tools are useful for quick visual or input checks. A dead pixel test can help reveal display issues that are difficult to notice during normal use, while a keyboard test can help identify keys that do not respond as expected.

These tools are designed for quick checks and early troubleshooting. For serious hardware issues, repair decisions or warranty claims, professional inspection may still be needed.
