Slow charge but no start

So when I opened it up the 0201 cap below the battery chip was fried. Battery was dead so I plugged in a good battery just to see if the system would boot. It booted I played some games on it. It actually docked find too. Just no charging. So I pulled it apart heated up the Caps, pulled off the ones that looked bad replaced them 1 by 1 with some from a donor board. Then I couldn’t get it to start, charge, or do anything. Apparently I flowed the solder on the fuel gauge and it shorted. Got that resolved. In the process I replaced battery ic and m92. Now I get .41 amps but no battery light and it won’t start. Could that shorted full gauge have fried my CPU?
