Coverage Map: What Coretest Validates
Coretest validates a machine across primary hardware domains with per-test status and progress telemetry. It is designed for intake verification, repair confirmation, and pre-handover confidence.
- Motherboard checks (ACPI, PCI, secure boot signals)
- Audio checks
- CPU stress suite with granular CPU test families
- Memory stress suite including row-hammer style patterns
- Drive diagnostics (SMART, read tests, NVMe-specific checks)
- GPU and graphics validation
- Network diagnostics for wired and wireless paths
- Battery checks for portable endpoints
Pre-Run Configuration Standards
Set configuration before execution to make results comparable across devices. Coretest supports fine-grained configuration in CPU, memory, storage, and network categories.
CPU
Choose cores/threads and specific CPU test families for load profile control.
Memory
Select memory test patterns and thresholds according to device class and expected stress window.
Drives
Choose SMART/read/write validations, including NVMe checks where supported.
Network
Run wired or wireless-specific checks, including loopback and communication validation.
Lock profile settings per service tier so technicians execute consistent diagnostic baselines.
Execution Patterns: Single, Batch, And Loop Runs
- Select only relevant tests when diagnosing a known subsystem issue.
- Use selected batch runs to validate cross-domain stability in one pass.
- Use looped runs when you need evidence for intermittent or thermal-linked behavior.
- Monitor live status and logs; cancel only when a hard stop condition is reached.
Loop reports are valuable for proving repeatability. Keep loop count and test selection documented in notes.
Reading Statuses And Acting On Failures
Coretest emits clear status states (idle, pending, running, success, error, cancelled, skipped). Treat error and repeatable cancelled events as escalation candidates.
- Hard failure: immediate escalation and isolation
- Intermittent/degraded: rerun targeted subset under controlled conditions
- Skipped/cancelled by policy: annotate reason in handoff report
Do not compare pass/fail confidence across runs that used different configuration profiles.
Report Handoff And Evidence Quality
At completion, save the Coretest report, verify report ID/session linkage, and attach operator notes for any non-trivial outcome. Export JSON when escalation or offline handoff is required.
- Open the saved report and confirm test status completeness.
- Attach remediation intent or replacement recommendation.
- Route the report to the correct owner/team in hierarchy.
Field Troubleshooting Playbook
Thermal Instability
Reduce parallel load and run focused CPU/GPU loops while monitoring trend direction.
Storage Slowdowns
Cross-check SMART outcomes with read/write behavior and interface type.
Network Variance
Separate local path checks from internet checks before concluding adapter failure.
