We love Real Life Learning! Today my kids learned how to disassemble & reassemble a laptop!
My poor DH has no idea what we do for school. We have several laptops and an old desk top computer. Today's lesson? Re flowing a motherboard. The kids main laptop, the one they mostly use for school, had the motherboard die on us a week ago. Today I taught them how to completely dis-assemble the laptop, what each part of the mother board was for, etc. With many HP laptops they get really hot under the bottom. This can cause the soldering to get a microscopic honeycomb shape to it, essentially introducing microscopic air bubbles. This prevents the computer from booting up. Since it's over 5 years old we can't find a new/replacement motherboard anywhere, even eBay. So the last resort is 'reflowing' - essentially you bake the motherboard at 385 degrees for between 7-10 minutes. This re melts the solder. The concept is to melt then re-harden the solder without the air bubbles.
Poor DH got home from work to find our futon, which we use a a second couch, pulled out covered in all the pieces of the computer. He was slightly horrified to learn how I was fixing the computer...lol
