    Use a USB-C Power Delivery charger that explicitly provides 20V ⎓ 3.25A (65W), together with a cable rated for that power; sharing the USB-C connector shape alone does not make other chargers compatible.

    Your laptop’s label specifies:

    • 20V DC
    • 3.25A
    • 20 × 3.25 = 65W

    HP’s 65W USB-C charger supports USB Power Delivery voltage profiles through 20V and has a maximum output of 65W, matching those requirements.^1^

    What to check on a replacement

    Look at the small-print Output section on both the charger and cable packaging:

    1. The charger must say USB PD or USB Power Delivery.
    2. Its listed outputs must include 20V ⎓ 3.25A or a higher current at 20V.
    3. Its USB-C cable must be rated to carry at least 65W.
    4. Connect it directly to the laptop’s charging-capable USB-C port, not through a hub or dock.

    A phone charger may fit but provide only 5V, 9V, or insufficient wattage. Microsoft notes that the computer, charger, and cable must all support the required charging standard and power level; otherwise, the computer might charge slowly or not charge at all.^2^

    Since you have already tested multiple chargers and the original still works, battery-driver resets and Windows repair steps are not indicated. The working original charger also makes a failed charging port less likely.

    Identify the exact HP Envy before buying

    Because some USB-C computers require a manufacturer-compatible charger, identify the precise model and confirm its supported adapter with HP:

    1. Press Start, type System Information, and open it.
    2. Note System Model and System SKU.
    3. Use those identifiers when purchasing from HP or asking HP support for the compatible USB-C adapter.
    4. Prefer an HP 65W USB-C adapter specified for that model, or a reputable USB-C PD adapter whose printed output explicitly includes 20V ⎓ 3.25A.

    Microsoft also recommends contacting the PC manufacturer to determine the correct charger where compatibility is uncertain.^3^

    Do not use a charger merely because its plug fits. Avoid adapters with no readable electrical ratings or ones that list less than 65W.

    Hi,

    Depending on the model, chargers typically have specific voltage, connector types, and internal chips required for proper operation. This is why using a charger that isn't the correct one for your specific model may result in it not working properly.

    This can be due to differences in voltage, connector specifications, and other factors.
