Replacement 45W HP Blue-Tip Adapter

This 45W AC adapter replaces the original charger for HP laptops that require a 19.5V 2.31A supply through a 4.5x3.0mm blue-tip connector. It accepts 100-240V input for worldwide use and includes the AC power cord. Built-in IC protection guards against over-voltage, over-current, overheating and short-circuit events.

Upgrade From Damaged or Lost 45W Unit

The adapter is a direct swap when the original 45W blue-tip charger fails, is lost or shows cable wear; it restores the same 19.5V 2.31A output without changing the power profile. The jump is worth it only if your laptop specifies 45W and the 4.5x3.0mm blue tip — higher-wattage or 7.4x5.0mm units will not fit or match the required current.

Simple Plug-In Installation

Connect the supplied power cord to the adapter brick, plug into a mains socket and insert the blue tip into the laptop port; no drivers or configuration are needed. What usually goes wrong is ordering without verifying the original adapter's 19.5V 2.31A rating and the exact 4.5x3.0mm connector, which leads to a physical mismatch or insufficient power.

Questions about this item

What connector size does the LX-65W adapter use for HP laptops?

The adapter uses a 4.5x3.0mm blue-tip connector designed for compatible HP Stream and Pavilion models; it will not fit 7.4x5.0mm ports.

How do I install the charger and avoid the common polarity mistake?

Plug the AC cord into the brick, insert the 4.5x3.0mm blue tip firmly until it seats, then connect to mains; the key error is forcing a 7.4x5.0mm port which this tip does not fit.

When should I replace the power cord or adapter?

Replace the cord if the insulation cracks or the plug overheats; replace the adapter if output drops below 19.5V 2.31A or the blue tip becomes loose in the laptop port.
