How to use

Connect the adapter to an AC mains outlet using the appropriate power cord for your region, then attach the 3-pin connector to the laptop power inlet until it seats securely. When connected correctly, the laptop will draw power and charge the battery while operating. Avoid bending or sharply twisting the cables and keep the adapter on a flat, ventilated surface during use to allow heat dissipation. Unplug from the mains before disconnecting the adapter from the laptop if the device is not in use for extended periods.

Recommendations

Use only the correct regional power cord and verify the outlet voltage matches local standards. Keep vents unobstructed and avoid covering the adapter while in operation. If the adapter becomes unusually hot, emits odors, or shows visible damage, discontinue use and replace it with an approved unit to prevent damage to the laptop or risk of fire.
