If you can get your hands on the Windows Update, you can probably extract the BIOS
How?
I can't find the exact model on their website, it seems like Acer produced this device as a low-cost deal specifically for the Indian market and decided to just... not support it?.
Which is very dumb.
update .exe
What .exe are talking about exactly? Is there some exe inside windows iso?
And idk what clevo is. Maybe a mass manufacturer of low quality computers (from my low effort search)
But you'll probably have to check each update and see if the "Supported Hardware IDs" match some sort of UUID in dmidecode. I'm not sure if those are supposed to match though.
Then there are some generic firmware update tools for Linux that might work, or might brick your laptop.
