Low Power Delivery from Surface Dock to Surface Book 2

Anonymous

I am really pleased with the performance of the MS Surface Book 2 for gaming. The GTX 1050 is a good card for the screen size when you turn the resolution down a little bit. Everything works well when plugged into the supplied wall charger, however when I plug into my Surface Dock and try to play games, Battery 2 (The Base Battery) drops to 4% within 20 minutes of gaming and the GTX1050 automatically disconnects, making the game hang.

This seems a little strange as the power supply on the Surface Dock is huge compared to the power supply that came with the device.

I see that the Dock power supply is 90W and the power supply with the Surface Book 2 is 102W. Would it make such a difference?

Can I just buy a larger power supply for the Surface Dock to get the required power to the Surface?

Hi Michael,

Thank you for posting us here in Microsoft community!

Surface Dock supplies 90 watts of power. Surface Book 2’s inbox charger supplies 102 watts. If the device is under heavy use, and using more than 90 watts of power, the Surface may be running off of battery power. As such, the power setting is not recognizing the dock’s power connection.

In this case, we suggest that you may use the inbox PSU and use USB-C for external devices to work around with this concern.

Keep us posted for further assistance.
