I faced two issues with the flash - first, flashrom didn't manage to backup two identical bins; which didn't bothered me since the laptop is currently in bricked state, so that bios wouldn't do me any good.

But, the worst part was the failure to flash the chip with the bios you provided. Any idea what could cause this? Is the chip itself damaged and the reason for the laptop to be bricked in the first place?...

Hi guys,

Hi Everyone,

My name is MagicHertz and I've always been curious about electronics. I'm giving it a serious thought about doing it professionally, but I really need a proper deep dive starting from the basics, which I already started doing with YT vids, but considering a course as well.

I came across this forum while looking for a laptop schematic and boardview, since I like hands on learning and I got just the right broken candidate to get going. =)

See you around the forum!
