Heard a guy at the parts counter in Phoenix say he fixes flickering laptop screens by baking the motherboard, which sounded insane.

I tried it on a dead Dell Latitude 7490 from 2018, and the thing powered right up after 8 minutes at 385 degrees. Has anyone else had a legit fix with this method, or did I just get lucky?

Wait, you put a whole laptop motherboard in your kitchen oven?

That 385 degrees is way too hot for a motherboard. You want to stay under 200 degrees Celsius, which is about 392 Fahrenheit. The goal is to reflow the solder, not cook the plastic parts into a puddle. Your oven probably just has bad temperature control and ran cooler than it said. A proper reflow needs a controlled heat gun, but even that's a temporary band-aid for a design flaw.
