Ok,
Now that is some serious testing. I'm pretty sure that I didn't understand a lot of it.
So if I just have the charger and the cable that came with the Surface, the add on keyboard, an External monitor connected to the mini display port, and an external USB drive, is that too much for the Surface to handle?
Do I need to unplug something in order to get rid of the Plugged in, Not Charging message?
Thank you for taking the time to test and share your results!
Actually, this is one of my standard configurations. When camping in the rv, I have and external USB drive attached and a TV via displayport to hdmi adapter. However, I do have the surface set to turn off the internal monitor when the case (keyboard) is
closed.
I double checked last night and yes, I get connected and charging. At some point I turn off the TV and leave the surface to its own devices - going to sleep/hibernating - and in the morning it is fully charged.
If the display is left on, esp. at higher brightnesses, I wouldn't be too surprised at this point if the battery continued to discharge.
Based on my experiences as related earlier in this thread, along with others experiments, I tend to agree that the issues have to do with the voltage drop across the wire along with the power supplied by the charging device. I have yet to have a problem
using the supplied charger and cable, though others have.
Perhaps this can be tweaked by MS, perhaps not. I thought about returning it for this reason but realize that I am enjoying too much. As long as I have a couple of chargers it will work with, it is not ideal, and certainly doesn't live up to the advertising
claims, but it is so good at other things that I shall stick with it and see if MS comes up with a fix.
Besides, I am passed the return date for Best Buy!
