Important Notes ⚠️

• This adapter is **non-original** (third-party) — not the original manufacturer’s charger. While safe and matching specs, some brand-specific features (e.g., firmware signalling) may differ.
• Verify your laptop’s original charger voltage, required amperage and connector size before purchase. Using incorrect specs can result in under-performance or damage.
• If your laptop originally required more than 45 W, using a lower-wattage adapter may cause performance throttling or instability.
• Ensure adequate ventilation for the adapter during use — smaller/cheaper units may heat up more under load.
