Questions about this item

How do I connect the 7.4 mm 5.0 mm barrel plug to the MSI GT72 charging port?

Align the centre pin and outer sleeve of the 7.4 mm 5.0 mm connector with the laptop's DC-in jack, push straight in until it seats firmly, and avoid angling the plug which can bend the internal pin.

When will the 330 W 19.5 V 16.9 A adapter need replacement?

Replace the unit if the output voltage drops below 19.5 V under load, the brick becomes unusually hot, the cable sheath frays near the 7.4 mm 5.0 mm plug, or the LED indicator fails to light.
