Charging a completely flat Surface Pro 3
A very short one - if you've got a Surface Pro 3 (and this may well apply to other Surfaces) and the battery is totally flat, charging it from a Surface Dock may not work.
If you see the light on the plug that connects to the Surface flashing, rather than showing a solid white light, swap to a "normal" charger to get the battery started. Once you've got some charge into the battery that way, you'll be fine to swap back to the Dock.
My skillset has matured somewhat since then, which you'll probably see from the posts here. You can read a bit more about me on the about page of the site, or check out some of the other posts on my areas of interest.
