DeviceTriage Diagnostic Center

Narrow the problem instead of guessing.

Start with the symptom, locate its boundary, and build a controlled test plan for your device.

Guided diagnosis

Narrow the problem in three steps.

Step 1 of 3

What are you experiencing?

Choose the closest symptom. This does not assume a diagnosis.

Diagnostic discipline

The goal is to gather evidence with fast, reversible steps.

Determine whether the symptom exists only in one browser, across one device, or throughout the network.

Test one browser, connection, permission, or profile difference instead of changing several settings at once.

A missing API, hidden hardware name, or denied permission is not evidence of physical failure.

Troubleshooting library

Read symptoms, causes, controlled diagnosis, and low-risk solutions.

Focused device tests

Test screen, keyboard, camera, microphone, audio, graphics, browser, and network separately.
