🔌 Not compatible with older 7.4mm center‑pin barrel connectors (though HP sells dongle adapters)
🧯 Some OMEN 17 and higher‑end gaming models require 200W or 230W bricks — always check the laptop’s underside label

🛠️ Quick Tips for Beginners
🧭 Look for “TPN,” “L1,” or “HSTNN*” on the adapter label for valid part numbers
🔌 Use only with HP laptops that accept the 4.5mm × 3.0mm blue‑tip plug
🧪 If laptop won’t charge, inspect barrel for dust, pin for bending
🧯 Label adapters clearly to avoid mix‑ups with 65W or 90W units
