Component level system board repair.
Hi. I am a tech at a laptop repair shop. I want to learn how to do component level repair on stuff. Laptop MBs, video cards, usb flash drives, etc. I'm sure that is a far away goal, but right now I don't know what the starting point is.
This week I recovered data from a flash drive that had been dropped. I was testing voltage aimlessly on the drive while it was plugged in and I tapped a refrigerator with a probe and the drive just suddenly came to life and I have no clue why. btw, I call it a refrigerator because that is what it looks like and I have not clue what it is actually called.
any advice to point me in the right direction?
Oh, also I have no formal schooling, certs, or anything. Just a mind for troubleshooting.
