Questions about this item
How do I connect the 20V 11.5A 230W adapter to my Lenovo Legion Y740 and what step is often missed?
Plug the 6 ft 3-prong AC cord into a 100-240V outlet, then insert the slim plug tip firmly into the laptop's DC jack until it clicks; the step often missed is not pushing the tip in fully, which prevents charging.
What maintenance or replacement will the 230W AC adapter need over time?
The 6 ft AC and DC cords should be inspected periodically for fraying or damage; the ruggedized case resists moisture, but if the cords or internal components fail, the entire 46.20 oz unit must be replaced.
What is the first limit reached when the 230W adapter runs continuously at full 20V 11.5A load?
The adapter reaches its maximum 230W output limit first; it cannot supply the 280W, 300W, or 330W required by higher-wattage Lenovo models, so sustained loads above 230W will cause shutdown or throttling.
