Questions about this item

How do I connect the 20 V DC output to my Lenovo 3443 notebook?

Plug the barrel connector firmly into the notebook's DC-in jack until it seats with a click; the step people miss is verifying the tip polarity matches the 20 V DC label before powering on.

What part will need replacement after the 24 month warranty period?

The AC adapter unit itself is the only field-replaceable component; internal capacitors and the output cable are not user-serviceable.

At what sustained load does the 65 W limit engage?

Continuous draw at 3.25 A triggers the 65 W maximum output power protection, causing the adapter to shut down until the load drops.
