45W HP Blue-Tip Replacement

This 45-watt AC adapter supplies 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre blue tip. It matches the original charger for a wide range of HP Pavilion and Stream laptops listed in the compatibility data. The unit accepts 100 to 240 volt input at 1.5 amps for worldwide use.

Replaces Lost or Failing 45W Units

It substitutes any HP charger carrying part numbers such as 741727-001, 719309-003 or PA-1450-36HE when the original is lost, damaged or no longer holds a charge. The upgrade is worthwhile only if your laptop requires exactly 19.5 volts and 2.31 amps with the blue-tip connector.

Plug-In Installation, Tip Mismatch Risk

Installation is a simple corded connection: plug the AC cord into the brick, insert the blue tip into the laptop, then connect to mains power. The common error is fitting this adapter to a model that needs a different tip size or a higher wattage rating, which will prevent charging.

Questions about this item

What clearance does the 4.5 mm by 3.0 mm blue tip need to plug into the laptop?

The blue tip measures 4.5 mm outer diameter and 3.0 mm inner diameter; ensure the laptop's charging port matches these dimensions exactly.

Which step is often missed when connecting the adapter for the first time?

Verify the laptop requires 19.5 V at 2.31 A and 45 W output before plugging the blue tip into the DC jack.

How can I tell when the adapter or its cable needs replacement?

Replace the unit if the blue tip becomes loose, the cable shows exposed wires, or the charger no longer delivers 19.5 V at 2.31 A.
