Hi, I have the same laptop and am currently facing the same issue. I have bought a ch341a from amazon, but I am very new to this stuff. I can't identify the bios chip. Could you help me identify if the bios chip is the one in the image below. Also, is it ok if I just flash the Engineering BIOS given or do I need to update anything on it.
