Looking for options other than scrap

Have a cb11 which one day stop recognizing the battery.  Plug it in and indicator blinks and it boots, but no battery detected.  Bought a replacement battery and figured just swap it in right?

Replacements (tried 2) both have the same result.  You can power the laptop up and it sees the battery, but they will not charge when the adapter is plugged in.  The indicator has no light whether plugged in or not.  battery_test just shows discharging even when plugged in.  And plugging it in when shutdown no indicator so can't charge it powered off either.  And as both replacements have no blinking indicator it doesn't seem to be a battery fault, but something in the power management. 

Tried hard reset (refresh button for 5s and then depress power) no change

Tried complete drain by removing battery, holding power for 30s, replace battery, plug in, boot no change

Feels like there is some charging circuitry that is fried, but i don't see any blow outs on the mainboard.  Basically if it sees a battery it can't push juice into it for an unknown reason.
