Power adapter HP 24es, 23.8-inch Display

[NiklasSh]

I have lost the power adapter for my HP 24es, 23.8-inch Display.

Product no: T3M78AA

I've found that the part number for the power adapter is 844165-001 or 844167-001, which seem pretty difficult to find.
So I'm wondering if anyone has any suggestion for another adapter to try.
Also, does anyone know the dimensions for the pin / port?

Hi @NiklasSh,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The HP 24es 23.8-inch Display typically requires a 19V, 65W power adapter with a compatible barrel connector. Here’s what you need to know to find a replacement.

Specifications:

• Output Voltage: 19V DC
• Output Power: 65W
• Connector Dimensions:
  • Outer diameter: 4.5mm
  • Inner diameter: 3.0mm
  • Pin: A center pin inside the connector.

Options for Replacement Adapters:

Original Part Numbers:
If you can locate HP part numbers 844165-001 or 844167-001, they will be your safest bet for compatibility. They are designed specifically for HP monitors like the 24es.

Third-Party Adapters:
Ensure the following specifications:

• Output voltage and wattage: Match 19V and at least 65W.
• Connector size: 4.5mm outer, 3.0mm inner with a center pin.
• Polarity: Center positive (most standard adapters are center positive, but always verify).

Universal Power Adapters:
Many universal power adapters come with multiple connector tips. Choose one that supports 19V output and matches the connector size. Ensure that it can deliver at least 65W to avoid underpowering the monitor.

Where to Find Replacement Adapters:

• HP Official Parts Store: Search for the specific part numbers on the HP website.
• Online Marketplaces: Amazon, eBay, or other marketplaces often have both original and third-party compatible adapters. Look for adapters specifically labeled for HP monitors.
• Local Electronics Stores: Check with stores that sell laptop accessories or monitors, as they often carry compatible adapters.

Note:

• Avoid adapters without clear specifications or reviews; using an incorrect adapter can damage the monitor.
• Measure the barrel connector size carefully if the dimensions provided here do not match exactly, as there can be slight variations

I hope this helps.

Take care and have a good day.
