The Blue uses a 2S LiPo battery. ~7VDC vs ~12VDC. In the specs that
William ref'ed look for section e, Power management, ii => 2 cell (2S)
LiPo battery charger.
I haven't checked the schematic, but you might have caused a problem.

Thanks for the response William,
I followed the directions online to put in a formatted uSD card with
firmware, held the boot button down (it's a momentary push button, not
an on/off switch) while plugging in a 3S Lipo (12V). No booting from
uSD happens . To double check I viewed the process on YouTube (for BB
Black) to make sure I was doing what was expected.
What do you think? I realize these boards are new (says Beaglebone
Blue Rev A2 on back) but I hope there isn't some sort of defect with
them. I used a DMM to verify that the push buttons are shorted when
depressed.
Anything obvious I'm missing?

Hello,
I do not have a beaglebone blue personally, but if you mentioned
it I'm not seeing if you switched the boot switch or not.

Scroll down to the "balloon" diagram, and look at the switch that
is nearly opposite of the 5v barrel jack.

Help! My BBBL just arrived Monday and was in the middle of
porting my quadcopter code to it. I was able to get 9DOF
measurements from it and decided to take it to the library
with me, so I put it back into the static bag it came with,
placed it in the original box in between the ESD foam it came
with and placed it into my backpack. When I took it out, I
found that it was unresponsive. I thought maybe I somehow
bricked it by not doing a shutdown -h before unplugging it, so
I tried to follow online directions on booting from an
external uSD card.
If I power the board from USB or an external 3S Lipo, all I
see is the blue ON LED, the LIPO status LED stuck at 75, and
the G and R LED's on (picture below). If I press the SD
button with the uSD already plugged in and apply power, I
don't see any blinking lights that tell me it's booting from
the uSD card.

firmware, I tried a 8GB and a 32GB uSDHC card, I tried 2
different USB cables. When plugged into a USB port, I can't
find the network access point to be able to login using
192.168.7.2, and also I can't ping the device over it's
wireless network after I had configured the wifi using connman.
I'm starting to think that the hardware was somehow damaged
(but I felt I took appropriate ESD considerations, and
transported it in its box).
This is my first beagle bone product ever (but have used many
Arduino's, RPI and Intel Edison). Is there some newbie mistake
I'm making? Thanks for your help in advance!
