⚠️ Things to Watch Out For
📉 Must be 15V 8A — lower‑wattage adapters won’t boot these systems
🔌 Connector is proprietary — not compatible with standard barrels
🧯 Always confirm model number before substitution
📏 Heavy brick — designed for desktop‑replacement laptops, not ultraportables
 
🛠️ Quick Tips for Beginners
🧭 Look for “DC IN 15V” near the laptop’s power jack
🔌 Confirm 4‑pin connector — not the smaller 2‑pin Toshiba plug
🧪 If laptop won’t power on, inspect pins for bending or corrosion
🧯 Label clearly to avoid mix‑ups with 15V/5A adapters
