.... battery fails to charge. Not only that, but when the AC adapter is plugged into it, no power light comes on to indicate that there is even AC power being provided to the system. ... a problem with the connection between the AC adapter port and the motherboard in the laptop. ... messages stating that the computer's AC adapter was not plugged in, even though the adapter was plugged into it, etc.) .... Has anyone else experienced this type of issue?
Yes. It is the
most common cause of laptop failure.
Moving the laptop while the AC/DC ballast is plugged in and jerking the cord connected to the laptop. Or tripping over this cord. Either way it damages the power connection soldered to the MB. Some laptops are designed for fairly easy repair of this connection, others require removal of the MB and delicate soldering.
Apple notebooks use a clever magnetic connection (patented) to prevent just this type of damage by cleanly separating the power cord from the laptop when people passing by either don't see the cord, or users forget their laptop is plugged in and start to carry it somewhere else.
How is Best Buy responsible, or Toshiba for that matter for user induced damage?
Looks like Toshiba uses a mount off the MB so it is easier but plastic holds it together and as my father used to say plastic is not an engineering material. Meaning it fails.https://www.youtube.com/watch?v=R55es41nwm8https://www.youtube.com/watch?v=zeuArf_4uwg
