Questions about this item

Will the 90 W rating cover continuous load without thermal throttling?

The adapter delivers a steady 90 W output across the 100 V to 240 V input range, matching the original supply shipped with compatible ThinkPad and Lenovo 3000 series models.

Does the brick stay quiet and cool during all-day operation?

The sealed 1.18" x 1.97" x 4.96" enclosure has no fan; it runs silently and relies on passive convection, so surface warmth is normal but it stays within certified limits.

Which cable do I need to plug this into the wall?

A standard IEC C7 figure-8 line cord is included in the retail box, letting you connect the 100 V–240 V input to any local mains socket.
