DIY Laptop Repair Guides
Step-by-step how-to articles and reference material for laptop technicians, repair shops, and DIY enthusiasts. 16 guides covering AC adapters, DC power jacks, batteries, LCD screens, keyboards, cooling fans, and common troubleshooting paths.

- Compatibility references — connector pin counts, wattage tables, eDP versus LVDS, OEM versus aftermarket trade-offs.
- Troubleshooting decision trees — when symptom X means the adapter, the jack, the motherboard fuse, or the battery controller.
