Wonder if someone got in trouble for this

Laptop motherboard with some "external" circuitry. Possibly a mistake in the original board design?

    If that were mine, I'd be looking to see what those "corrections" are connected to. Might be a little after-manufacturing improvements for gaining access to your secure personal data.

    ...very, very common

    Maybe not so much "mistakes", but definitely "after-thoughts".

    What makes the difference is the quality of the work.

    Maybe it's an upgrade or a feature? :innocent:

    Back in the mainframe days we had an upgrade that was a piece of wire wrap wire and instructions on where to wrap it. It seemed like it was a $20k upgrade.

    The laptop won't power up :( if it did I would remove some of those wires and see if it still worked. That might provide some clues on if it were a mistake. I could see it as an afterthought, and the quality of the work is horrible. It is about 10 years old though.

    They also glued the DC jack to the mobo with a huge glob of something. Now when you drop the laptop and it's plugged in you probably break the mobo instead of just the jack. It is rare I take apart a laptop to fix it, but this was my moms so I offered to. It would seem every time I get into something like this I get the oddest issues.

    This thing is going to recycle. The DC power jack isn't shorted, but when you plug in power it overloads the adapter into some fault mode as if it were. It stops producing power until the AC side is cycled. The power adapter itself tested okay for both voltage and current.

    Circuit board modifications are not unusual especially for minor changes. These changes are usually done as a result of testing or based on customer feedback. Those little board mods could be the reason why it's lasted as long as it's had. It's also testament to the skill of the people who performed those mods.

    Same with mini's and supermini's, mind you the same upgrade cost a bit less. Those were the good old days.
