How do I flash the bios of the Acer Aspire ES1-521-266Z?

When I turn on the laptop, it opens up to "the screen of death" meaning that it's just a black screen. I already replaced the ram and hard drive, but it still turns on to a black screen. I downloaded the BIOS of the same model on a USB thumb drive, but I don't know what to do to flash the bios. I pressed the Fn and esc key with the usb drive plugged in, and it's fans are running at full speed and the screen is constantly turning on and off, and it still doesn't turn on after 40 minutes. I learned that from an Acer Aspire 1 bios flash tutorial, so I don't know if it also works on this laptop as well. Does anyone know how to fix this specific model?

This procedure is only used when the bios is corrupted. Have you tried resetting the lition battery?

Did you try to update the bios before the problem occurred?

I don't know how to update the bios if the screen only opens to black, it turns on, but it only goes the the death screen.

Have you tried disconnecting the lition battery and pressing the power button for thirty seconds? Also try leaving the notebook off for a few hours and with the battery disconnected to discharge the capacitors.

I've done the first one, and nothing happened. I'll try the second option
