Suits laptops requiring this exact voltage and tip

The centre pin and barrel dimensions are the single detail that decides physical fit. Match these numbers against the original adapter or the laptop service manual before ordering.

Questions about this item

Will the 7.4 x 5.0 mm connector fit my laptop charging port?

The adapter uses a 7.4 mm outer diameter and 5.0 mm inner diameter barrel connector; match these dimensions to your device port before purchasing.

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

Connect the supplied power cord to the adapter brick first, then plug the barrel tip firmly into the laptop before switching on the mains supply.

What maintenance or replacement will this 135 W adapter need over time?

Inspect the power cord and barrel tip periodically for fraying or looseness; replace the entire unit if output voltage drops or the brick becomes excessively hot.
