Questions about this item

Does the 65W adapter run hot or make noise when powering a laptop all day?

The 65W unit includes over-heat protection and operates from 100-240V AC at 50-60Hz with no fan, so it stays quiet during continuous use.

What must I already have for this 18.5V 3.5A charger to work with my HP G42?

Your HP G42-230US or G42-240US must use a 5.0mm inner by 7.4mm outer barrel connector and accept 18.5V at 3.5A.

Will this 65W 18.5V supply safely charge an older HP G42 that originally shipped with a lower-wattage brick?

Yes — the adapter delivers a fixed 18.5V at up to 3.5A, and the laptop draws only the current it needs, so a 65W unit is safe for models rated for less power.
