Will this 230W adapter work with my HP laptop that originally came with a 150W charger?

Yes, you can safely use a 230W adapter on a laptop that requires 150W, as the laptop will only draw the amperage it needs, and the larger adapter will actually run cooler.

Does this power adapter come with the AC wall cable?

No, this product includes the power brick only and requires a standard IEC C13 power cable (kettle lead) to connect to the wall outlet. You can reuse your old cable or [purchase a compatible 13A power cable from our store here](https://scccltd.com/products/computer-power-cable?_pos=7&_psq=13a+power+cable&_psid=678beb42e&_ss=e).

Why does my HP laptop say "plugged in, not charging" with my old adapter?

This error usually occurs when the tiny center communication pin inside the 7.4x5.0mm connector of your old charger breaks, and replacing it with this new OEM adapter will fix the issue.

Can I bring my HP laptop to your Hong Kong store to test the charger before buying?

Absolutely, we highly encourage you to bring your laptop to our Sun Cheong Computer Co. Ltd. physical store in Sham Shui Po so our staff can test the fitment and charging status on the spot.

Is this an original HP branded charger?

This is an OEM (Original Equipment Manufacturer) adapter, meaning it is produced in the same factories and to the same technical specifications as the branded versions, offering identical performance at a better value.

Full Product Description

High-Power 230W Delivery for HP Workstations

This OEM 230W power adapter provides the stable, continuous high-current power required by HP's most demanding mobile workstations and gaming laptops. Standard 65W or 90W chargers simply cannot supply enough energy for laptops equipped with high-end dedicated graphics cards and multi-core processors. By delivering a robust 11.8 Amps at 19.5 Volts, this adapter ensures your laptop's battery charges efficiently even while rendering 3D graphics, compiling code, or running intensive gaming sessions.

Exact 7.4x5.0mm Center Pin Compatibility

Featuring the classic HP 7.4x5.0mm barrel connector with a smart center pin, this charger ensures your laptop correctly identifies the power source and accepts the full 230W charge. HP laptops use this center pin to communicate with the adapter; if the pin is broken or missing on your old charger, the laptop will throttle its CPU performance and refuse to charge the battery. This brand-new OEM replacement restores full functionality and performance to your machine instantly.

Pro Tip from Our Technicians

Always match the Voltage (V) exactly and ensure the Amperage (A) is equal to or higher than your original charger's specifications. Our Sham Shui Po repair specialists warn that using a lower-wattage adapter (like 150W) on a 230W laptop will cause the power brick to dangerously overheat. Also, remember that this adapter requires a heavy-duty C13 power cable to handle the high wattage safely.

Please Note: This unit is sold as a replacement brick. The 3-prong power cord (kettle lead) is not included. If you need a power cable, please click here to add one to your order.
