I have an Acer Aspire E-15 E5-511-COPC laptop that was brought 7 years ago. It was working perfectly although sometimes a sound would suddenly whir for about 10 seconds (i think the fan or hard drive) then stop. When i turn on the laptop by pressing the power button, the screen stays black but the fan turns on. I’ve also tried to connect the laptop to a monitor via an HDMI cable but i wasn’t able to view the screen on the monitor either. Before, i would hear the fan noise and some mechanical whirring (probably the Hard drive and other stuff) back when it was working. Now i ONLY hear the fan noise. Ultimately, it isn’t booting up.
