No POST / no boot
- Reseat RAM and SSD; try one SODIMM if unstable.
- Listen for beep/LED codes if documented; external monitor to rule out panel.
- Strip to minimal devices β USB hubs and docks can confuse early boot.
Thermals & noise
- Repaste if CPU/GPU spike to throttle under light load after a poor job.
- Clean dust from fins yearly; replace dried thermal pads on VRM where specified.
