I hope so. There was a green LED and a second one blinking during charging. Eventually the LEDs died and now it's dead. Strangely it booted after many attempts

I hope so. There was a green LED and a second one blinking during charging. Eventually the LEDs died and now it's dead. Strangely it booted after many attempts once, and then it gave up ever since. Power cycling has the LEDs all blinking twice, then they are dark again. I tried different chargers - makes no difference.
