But of course I already assume you did basic trouble shooting like reloading the OS and have proper anti-virus and malware protection.

Replacing hardware is always the last step.

Except that it works when docked, but not when undocked. Usually it's the docked connection that starts to fail (or battery charging, or external keyboard and mouse, or....)

Could be damage to the motherboard caused by fluctuating AC current? One of the cords I had been using was old and it would stop sending current if was moved a certain way.

Either that or the trojans. But I don't see why trojans would hurt performance when it's undocked but not when it's docked.

The battery tends to help buffer against that sort of thing, almost like a UPS.

I know the power port usually has 3 or 4 thick metal wires soldered to the motherboard. They can break from cramming the power cable in too hard.

Yep, sure do. I've fixed acouple and you can make a good profit of it because the powerjack is an inexpensive fix, but your labor for having to tear shit all the way apart is good.

Back in the early '90s about 80% of the cost of my BMW K75RT came from repairing the keyboard connector area on motherboard, using a technique I developed for repairing the surface mount components by hand.
