laptop motherboard repair how?

I keep seeing ads in the local newsgroup from people looking to buy broken laptops (and Ipods too for that matter), so I suspect they are transplanting. Either that, or they are hoping the problem is insignificant and they can get it cheap enough that the time spent fixing the problem provides a profit

Surface mount technology requires a rework station; for repairs at a professional level. Disassembly/reassembly is a PITA with laptops. Chips are not always easy to get.

Given the three points above, I doubt their claim.

yah it sound like they are frankensteining them in other word taking pull out bgoard and transpalanting them to your unit

A hot air rework station speeds up the work, but it can be done by hand under a stereo microscope, with the proper training. I did surface mount rework by hand on almost every board I worked with at Microdyne. It was faster to do it myself, than wait for the rework dept. to do it, then have it inspected. I did the repairs, tested the board, had it cleaned, then inspected after I finished. They intentionally "misplaced" some custom embedded CPU boards for 10 months

My guess is that most failures are either damaged connectors or failed electrolytics, so most of the work is in the disassembly/reassembly.
