Checks to complete before attempting device repairs.

A rushed repair attempt can erase files or make a fault worse. Use a sequence that separates software, network, storage and hardware problems without taking unnecessary risks.
1. Preserve essential data
If the device still works, back up documents, photographs and important information. Verify the copies open elsewhere. Before external service, consider account security and personal privacy.
2. Describe the exact symptom
Record error messages, timing, activity and frequency. A laptop that crashes in one program needs different investigation from one that cannot power on.
3. Inspect power and heat safely
Check suitable chargers, undamaged cables and ventilation. Do not open power supplies or keep using swollen batteries or equipment emitting a burning smell; seek qualified service.
4. Check space and updates
Review free storage and pending system updates. Update through official routes with adequate battery charge. Avoid deleting unknown system files just to free space quickly.
5. Isolate apps and connections
Determine whether the problem occurs in one program, user profile or network. Another app or connection can help distinguish a service issue from a device-wide problem. Never hand passwords to unverified technicians.
6. Use official diagnostics
Built-in tools may reveal memory pressure, storage health or recurring errors. Record indicators without running destructive commands you do not understand.
7. Compare repair and replacement
Request a written description of faults, parts, costs, timings and warranty terms. Compare with device age and needs. Do not approve unnecessary access to private files.
Effective triage puts safety and your information ahead of instant fixes.
