Latitude 7290 + WD15 Docking station
I bought a used Latitude 7290 + a used WD15 docking station but not working properly.
When the laptop boots up I got error message that says an undersized 60W power adapter is connected BUT this is not true, the WD15 came with a 180W power supply.
If I press F1 to ignore and continue boot process then the system properly boots up, Win10 gives error message the system slowly charging (but charging), the ports I already tried (HDMI, VGA, USB) are working.
I went through on FAQ for WD15, installed the latest BIOS and drivers.

When the WD15 has a 180W power supply attached, it can pass up to 130W to the attached system, although not all systems will actually try to draw that much. I'm actually surprised that a 12-inch Latitude 7290 requires more than 60W. Anyway, this problem has been reported on the forums before, and it always comes down to either a bad WD15 dock unit or a bad dock power supply. If you happen to have access to another dock and/or power supply, you can figure out which one is the culprit. Otherwise, it might be easier to just exchange the whole setup if possible.
