Maintenance checklist
| Area | Good habit | Why it matters |
|---|---|---|
| Updates | Keep OS, browser, apps, and drivers current | Security and stability |
| Backups | Copy important files regularly | Recovery from failure or mistakes |
| Storage | Keep free space and check drive health | Performance and data safety |
| Cooling | Keep vents clear and manage dust | Prevents overheating |
| Security | Use strong passwords and MFA | Protects accounts and data |
| Cleaning | Clean carefully using suitable methods | Prevents dust and physical wear |
Troubleshooting mindset
Troubleshooting works best when you change one thing at a time, write down symptoms, check recent changes, separate hardware from software possibilities, and avoid panic clicking.
If a storage device is failing or files are very important, stop unnecessary use and get qualified data recovery advice. Random repair attempts can make recovery harder.
Common symptoms and possible areas
| Symptom | Possible area | First safe thought |
|---|---|---|
| Slow startup | Storage, startup apps, updates | Check drive health and startup load |
| Random shutdown | Heat, power, battery, hardware | Check temperatures and power stability |
| No internet | WiFi, router, DNS, ISP, device settings | Compare with another device |
| App crashes | Updates, corrupted files, memory, bugs | Check logs and reinstall carefully if needed |
| No display | Monitor, cable, GPU, power, sleep state | Check simple physical connections first |
