Compatible HP G56 models

This 65 W AC adapter is built for the HP G56-123NR, G56-129WM and G56-130SA notebooks. It supplies 18.5 V at 3.5 A from a worldwide 100-240 V input. The package includes the power brick and a US-standard cord.

Plug fit and common issues

The barrel connector measures 5.0 mm inside and 7.4 mm outside, matching the factory jack on the listed models. A loose or intermittent charge usually means the tip is not fully seated or the centre pin is bent. Verify the dimensions before ordering.

Sustained operation behaviour

Over-voltage and over-heat protection circuits engage during prolonged use to keep output stable at 65 W. The adapter runs continuously at 50-60 Hz without thermal throttling under normal indoor conditions.

Questions about this item

How can I confirm the 65W 18.5V 3.5A adapter is working after plugging it into my HP G56?

The laptop should show the charging indicator and the battery percentage should rise; the adapter itself runs silently with no fan.

What comes in the package and is a wall cord included?

The box contains the 65W AC adapter and a US-standard power cord for the wall outlet; nothing else is needed.

Which connector size matches the HP G56-123NR, G56-129WM and G56-130SA models?

The tip has a 5.0 mm inner diameter and 7.4 mm outer diameter, the size specified for those HP G56 models.
