Quick or complete?
Quick Check covers essential signals and observations. Complete Diagnostic adds deeper checks such as microphone noise, display patterns and manual condition review. Both support all five profiles.
You control the session
Pause, skip unavailable checks or retest after a fix. Timed-out checks remain incomplete. A received signal is not a hardware certification. Recovery is optional and retains only coarse outcomes for 24 hours.
