Hi, my laptop's screen turns black after I wrongly downgrade my bios. It went blank during the update. So, I hold the power button to shutdown then turn on again. The next thing i knew is the black screen. I've already tried to unplug the battery and ac and press the power button for 60secs, even tried replacing the CMOS battery but none of those work, and the bootable USB with my bios on that too, but it not working.
Mine is Acer SP314-51 with Windows 10.
