PD2200 Pen Display – No Power or Won’t Turn On

If your PD2200 pen display isn't powering on, follow these steps to troubleshoot the issue:

1. Check All Cable Connections

   • Make sure the following cables are securely connected:

     • Power cable and adapter (for electricity)
       

     • HDMI cable (for video signal) - for a desktop with a separate graphics card (GPU), please connect this cable to the GPU, not to the motherboard.

     • USB cable (for pen and touch input)
       

2. Confirm the Power Source

   • Plug the power adapter directly into a working wall outlet (avoid power strips or extension cables).

   • Check whether the power indicator light on the PD2200 turns on.

   • If the light does not turn on:

     • Try a different wall outlet

     • If possible, test the power adapter with another compatible device

     • Ensure the adapter brick is not loose at either end

3. Inspect the Power Adapter and Cables

   • Make sure the power adapter is the original one that came with the PD2200.

   • Check for:

     • Bent pins

     • Frayed or damaged cables

     • Loose connections at the adapter brick

   • If the adapter feels unusually hot or makes noise, unplug it immediately.

4. Restart and Reconnect

   • Turn off your computer.

   • Disconnect all PD2200 cables from both the display and the computer.

   • Wait at least 10 seconds.

   • Reconnect the cables firmly.

   • Turn your computer and the PD2200 back on and check whether the PD2200 powers up.

5. Test With Another Device (If Possible)

   • If you have access to another laptop or desktop:

     • Connect the PD2200 to the second device

     • If it powers on there, the issue may be with your original computer's USB or power delivery

6. Check for Indicator Light Behavior

   • No light at all: Power issue

   • Light turns on, but the screen stays black: Likely a signal issue. Please refer to this article: "No Signal" Troubleshooting (for PD2200).

   • Light flickers: Possible loose cable or failing adapter.
