This sounds like an operating system boot loader problem. When a device turns on, it gives permission to the operating system (in this case, Android) for a very small number of devices, such as the CPU and the power supply. As the operating system boots up, it requests and receives more and more permissions. When the device does not get boot loader permissions though, it cannot boot. This is something that will have to be resolved through Acer customer support. Hope this helps.
