Mine died just now and was powered by roboticscape with 2S lipo and USB.
Cape is okay, BBB deadbit miffed about this...
No possible DIY repair ?

If you do not use it properly, it will be damaged. That applies to every
electronic circuit ever designed. I would have stopped using the circuitry
after the second try.
I would be happy to look at your circuit and see if I can identify what the
issue might be.

Gerald: I have 2 BBBs that will give a single brief flash of the power LED
when the power button is pushed, as described by others. It will not
sustain the power LED on nor boot up. When I power it from the barrel
connector (Adafruit regulated 5v power source / AC to DC 5v 2A) while on a

I now have 4 damaged or dead BBBs. On this last board (Element 14), I had
only a stepper motor driver board connected (Pololu DRV8834), and nothing
else. The DRV8834 was initially drawing power from the VDD5v on the BBB.
The BBB "blacked out" twice while nothing was happening and while connected
The flashing LED indicates excess current is being drawn by the processor.
This can be related to damaged I/O pins or power supplies that are not well
regulated..

I have the same issue, already 3 boards has died.
any solution, i tried to use optoisolator/pwm and noting. the BBB is a bad
board.

I have been having this same issue where the LED blinks once when 5V DC
power is applied. I would have to plug and unplug the DC adapter pin, or
press the power button several times before the LED holds steady and the
BBB boots. No such problems if powered by USB.

Hi, How many time did you pressed the power button to get it on? did you
only connect the 5vdc power supply or also the Usb cable to computer? I'm
having the same issue
I tried what it says here:
http://elinux.org/Beagleboard:BeagleBone#Board_Does_Not_Power_On.2C_Power_LED_Flashes.5BAll_Revision
I tried the listed fixes and did not get anything to work.
I tried flashing, using different power sources. In the end, I decided to
switch my system over to use a Rasp Pi 2. The BeagleBone is in a box and I
do not plan on using it again.
Hope you figure something out! I just didn't want to waste
The power supply I bought is from AdaFruit, which I expected to be well
suited to my BBB.
I haven't yet tried booting from an SD card, so I'll do that this evening.

I tried booting from an SD Card and got nothing. I tried a different power
supply, and it won't boot.
Really not happy with the BBB as I've only used it a handful of times. It
died after I pressed the Reboot button, which I now know can cause it
issues.
I think I'll buy the RPi2 and not mess arou
I suggest you switch to a \different power supply. A good one.

My Rev C BBB purchased from Adafruit just died on my in the exact same way.
I can't get it to boot at all whether connected to USB or 5V power supply.

I have seen this before. The USB path and 5VDC paths are different through
the PMIC. It is possible that the PMIC has sustained some damage or it
could be the 5VDC power supply is not powering up properly, where it has a
voltage spike, causing the PMIC to shutdown.

Identical problem this morning: BBB boots fine when powered by USB, but
not when powered by a 2.0 mA rated 5.0 V DC power supply (nicked from some
other device). BBB power LED blinks continuously. This power supply has
worked with this BBB in the past.

Hi, there,
I also have the power problem in my two Beaglebone black, Rev C. One of my

once.
I have disabled the HDMI in Env.txt and use six p
http://beagleboard.org/getting-started. I was happy to see, the
programs on the website worked just fine on my board. Thus, I was able
to conclude that strangely, my BBB board didn't like 5V external power
source!
The BeagleBone Black & BlueSteel Basic seem to be extremely sensitive to

I had a similar problem- my power LED would just continue blinking when
connected to a 5V power source. This meant there was something wrong.
First, I checked if my BBB was still alive. To find that, I connected my
board to a computer via USB. Surprisingly, this time power LED turned on
normal
