No one is talking about running wires all over the board. The original portable power supply was not very well designed from the start, with instabilities that could send VBat straight to the +5V rail (especially with bad capacitors) and weak current handling which makes it impossible to run it without a charged battery.
The photo above just shows how you can power your portable with regulated +5V DC to test if it is working, bypassing the original power supply stages.
Obviously.
I am talking about if you do a redesigned hybrid, how are you going to get 5V out to run the rest of the machine? A patch wire. of course.
Trying to avoid that... You could use the gate control wire to feed it down but that's not a good option ether because thats an awful small connection to hold the entire 5V bus.
Also the AC does not pass directly over into the battery, there is a MOSFET in between. Sure, it is a simple switch but the window comparator directly controls this switch.
