Respuesta a "My Acer Aspire E1-531 suddenly won't power on?"On the back of the laptop see if you can locate a pinhole usually it has a small symbol beside it. This contains a switch that would disconnect the small bios battery press and hold for 60 seconds with a small paperclip with the battery and power disconnected. Proceed to press the power button a few times before connecting battery or power supply. Boot without battery until you can get into your operating system . After this computer boots and everything is working then you can install the battery while the system is on to see if the battery will start to charge.
