Questions about this item

What length power cord does the 135 W adapter include?

The adapter ships with a total 10 ft long power cord, combining the mains lead and the DC output cable into one continuous length.

How do I connect the adapter to the IdeaCentre Flex 20, and what step is often missed?

Plug the DC barrel connector firmly into the Flex 20 power port until it clicks, then connect the mains plug to a 100-240 VAC outlet; the step often missed is ensuring the barrel seats fully before powering on.

Which protection components may degrade and need replacement after extended use?

The internal smart chip and isolation materials that provide over-current, over-voltage, short-circuit and overheating protection can wear over time, so the entire adapter should be replaced if charging becomes unreliable.
