I have the display screen dock system that hooks up to my surface studio, but it wont charge my computer anymore. It is still displaying to the screens, but not charging while it's connected. The magnetic connector is doing a slow blink. I have already tried disconnecting the charger, unplugging it from the power source, restarting my computer, and doing a hard reset ( holding the power and the volume up button for 15 seconds), but nothing is working.

    Hi Chelsey DeFrancesco,

    Welcome to Microsoft Q&A!

    I know how stressful it is when your Surface Studio displays through the dock but suddenly stops charging. Since you’re already seeing the slow‑blinking Surface Connect light, that gives us a clue about what can be happening:

    • The dock’s power delivery is not supplying enough wattage
    • The dock detects a fault on the power side
    • The connection is physically obstructed or not making full contact
    • The dock’s internal power circuitry is failing

    Because your displays still work, the data/video path is fine. The failure is specific to the power delivery portion of the dock. The Q&A Assist has pointed you to the right path, so I'll just add some suggestions you can consider:

    1. Try plugging the Surface’s original power adapter directly:
      1. If your Surface does charge, the dock is confirmed to have a power-delivery failure.
      2. If it does not, the issue may be with the Surface's internal charging circuitry. Figure that out will lead you to the correct place to resolve this issue.
    2. If the dock is overloaded, it may refuse to send power. Disconnect (if) anything plugged into the dock that uses power (e.g. USB drives, monitors with USB‑C power, etc.).
    3. Surface docks sometimes blink when the outlet doesn’t deliver stable voltage. Plug it directly into a wall outlet without a power strip just to test.

    If the slow‑blinking connector continues and your Surface charges normally with the original charger, then the dock’s power section has failed. At that point, your best option is replacement through Microsoft or your retailer, depending on warranty.

    It sounds like you're experiencing an issue with your Surface Studio dock not charging your device, even though it is still able to display to external screens. Here are a few troubleshooting steps you might consider:

    1. Check Power Supply: Ensure that the power supply connected to the dock is functioning properly. If possible, test it with another device or try using a different power supply to see if the issue persists.
    2. Inspect Connections: Make sure that all connections are secure. Sometimes, a loose connection can prevent charging.
    3. Firmware Updates: Ensure that your Surface Studio and the dock are running the latest firmware. Sometimes, updates can resolve charging issues.
    4. Dock Compatibility: Verify that your dock is compatible with your Surface Studio model. Not all docks support charging for all devices.
    5. Power Budget Policy: If the dock's total power budget is exceeded by connected devices, it may not allocate power for charging. Disconnect any unnecessary peripherals to see if that resolves the issue.

    If none of these steps resolve the issue, it may be a hardware problem with the dock or the Surface Studio itself, and contacting Microsoft support may be necessary.
