In the process of nodding my bios(grubbing) I happened to change a setting that bricked my bios this resulted in a booting issue. Whenever I tried to boot my laptop, the keyboard rgb would light up but the screen would remain black. I then purchased a ch413a programmer to re-flash the bios, to it default state. I then attempted to flash the bios with the bios file I found on acer’s website. Now anytime I try to boot, the screen remains black and no keyboard lights, although the power light blinks goes blue and then goes away. Is there something I am doing wrong?? If anyone could take their time to help, I would really appreciate it. Thanks !
