I killed my AW15R3 (service tag: 2TF61G2) by erasing all secure boot variables (don’t ask me why i did it). But before I did it, I had saved them on my thumb drive. After that, the laptop didn’t start at all. It started flashing and beeping a LCD error (i have a video of that, but i can’t post it here due to the forum rules). There is no image on the screen, just blinking keyboard with power button and beeping.
The bios version was 1.9.0. I’m 99.9% sure that’s not a hardware problem, it had worked perfectly fine until I’ve done it.
So I’d brought the laptop to an unauthorized service where they made a dump of the old bios and flashed a new one (they found it on the internet). After that started to work, but it wasn’t a great experience because there is a hassle with powering on (it might go to BSOD with error code WHEA_UNCORRECTABLE_ERROR). Now Windows doesn’t boot due to some driver issue and I wonder if there is a way to revive my old bios before new OS installation.
Thanks in advance.
