One Adapter, Two HP Notebook Connector Generations
Replacing an HP business notebook power adapter is not always as simple as matching the wattage. Older and newer HP systems can use different barrel connector sizes, which is why the HP G6H43AA#ABA 90W Smart AC Adapter is particularly useful as a replacement and backup power solution. It uses HP's 4.5mm Smart Pin connection and includes a 4.5mm female-to-7.4mm male conversion dongle for compatible HP notebooks using the earlier 7.4mm connector.
The G6H43AA#ABA, also identified by the base part number G6H43AA, is an HP 90W Smart AC Adapter designed for HP Business Notebooks and Tablet PCs. HP specifies 90W output and a 4.5mm AC jack, while the included conversion dongle provides connection versatility for compatible systems with a 7.4mm input. The right-angle 4.5mm connector also helps reduce cable bending around the notebook power port.

Compatible Devices
HP officially describes this Smart AC Adapter as compatible with HP Business Notebooks and Tablet PCs that support the required Smart AC adapter specification. The primary device categories include:
- HP EliteBook Business Notebooks
- HP ProBook Business Notebooks
- HP ZBook Mobile Workstations
- HP Business Tablet PCs
- HP Business Notebooks with 4.5mm Smart Pin input
- Compatible earlier HP Business Notebooks using a 7.4mm input through the included conversion dongle
Compatibility should be confirmed against the exact notebook model, required wattage, and connector configuration. HP notes that not every model is available in every region.
4.5mm Smart Pin and 7.4mm Conversion
The connector configuration is one of the most important characteristics of G6H43AA#ABA. The adapter has a 4.5mm Smart Pin connection, while the included conversion dongle changes the connection to a 7.4mm male connector for compatible earlier-generation HP notebooks.
This does not mean that every HP notebook with a 4.5mm or 7.4mm jack is automatically compatible. The notebook must also support the required 19.5V / 90W Smart AC power specification and compatible HP Smart Pin identification.
Replacement & Maintenance
A damaged AC adapter can cause intermittent charging, a notebook that stops charging under load, unexpected battery discharge, or a system that does not recognize the connected power source. Replacing the external adapter can restore normal power delivery when the notebook itself is functioning correctly.
The G6H43AA#ABA is particularly useful where connector compatibility is a concern because the standard 4.5mm Smart Pin connection can be converted to the older 7.4mm HP connector format using the supplied dongle.
Portable Design for Business Use
HP designed the 90W Smart AC Adapter as a portable power source for mobile work environments. Its compact form is suitable for carrying between an office, home workspace, meeting room, or business travel location.
The right-angle 4.5mm connector is also intended to reduce cable stress around the notebook power connection, which can be useful when the adapter is connected in confined spaces or while the notebook is being used on a desk.
