⚠️ Things to Watch Out For
📉 Must be 16V — 19.5V adapters may damage older VAIOs, 12V/13.5V won’t boot them
🔌 Connector is pin‑barrel — not compatible with plain 5.5 mm barrels
🧯 Always confirm “DC IN 16V” on the laptop label before connecting
📏 64W rating is sufficient for ultraportables, but some desktop‑replacement VAIOs required higher‑wattage 16V bricks (up to 6A)
 
🛠️ Quick Tips for Beginners
🧭 Look for “DC IN 16V” near the VAIO’s power jack
🔌 Confirm connector: 6.0 mm × 4.4 mm with pin, center‑positive
🧪 If laptop won’t power on, inspect pin for bending or corrosion
🧯 Label clearly to avoid mix‑ups with Sony’s 19.5V adapters
