HP 608428-001 90W AC Adapter, 7.4 mm Connector

Keep compatible HP notebooks ready for work with a 90W AC adapter designed for dependable daily charging and system power. This replacement adapter is intended for HP systems that use a 7.4 mm connector and is well suited for IT teams standardizing spare parts across user deployments, service inventory, and bench repair workflows. A 90W adapter provides the headroom needed for many business-class notebooks that draw more than basic charging power, helping avoid underpowered operation during active use. The power factor correction design supports efficient AC input behavior, which is valuable in environments where adapters are used continuously at desks, in conference rooms, or as field replacements. For procurement teams, this part makes sense when the goal is to restore a known-good power path without changing the user’s existing hardware setup. It is a straightforward replacement component that helps reduce downtime, simplify support, and keep mobile workers productive.
