I have A3000 that have issues booting up, constant boot - reboot cycle and usually when it's warm. I did have battery damage on it, and it looks like damaged something, because when I press down in certain area next to the battery, the A3000 boots fine. I did not have time to really fix it.
I would press down on all socket-ed chips, maybe got loose during shipping.
If you need some spare parts, just let me know.
