[Solved] OpenROV Dead ? no more boot or boot music



hi folks,
my openrov was working fine, it was plugged in my office, i left it plug for 20min and when i cam back, no more leds (except one) and no more cockpit view
Now when i plug it, no beep music, i ve reflashed the sd, and smae, and without sd card no beep either.
here is a short video

Any idea what went wrong? what should i check?
thx for your time


changed the battery in the body of the rov, and now it works.
i thought boot only depends of usb b power, not the life
sorry for the trouble, might serve somebody else
