Power & battery — adapters, cells, safety
Laptop workbook — parts, assembly, firmware, and troubleshooting next to the video.
Adapters
- Match voltage and sufficient wattage (GPU boost pulls spikes).
- USB‑C PD needs a profile that meets peak system draw — undersized chargers throttle performance.
Batteries
- Prefer vendor-shaped replacement packs from reputable sources when possible.
- Rebuilding packs from loose 18650s involves spot welding and BMS knowledge — high risk; not covered as a beginner project.
