Questions about this item

What input voltage range does the 85 W adapter accept?

It accepts 100-240 V at 1.6 A across 50-60 Hz, so it works on mains supplies worldwide without a voltage switch.

What comes in the box for mounting or connecting the adapter?

A detachable power cord is included; the adapter body has no mounting brackets and sits on a desk or floor.

How do you install the adapter, and what step is often missed?

Plug the power cord into the adapter, connect the barrel tip to the laptop, then plug the cord into a live mains socket — skipping the wall-outlet check is the common mistake.
