MacBook Wont turn on over battery (just ac could turn it on )

My macbook can be turn on only with ac power adaptor. (battery detected but not functional)

If i unplug the ac its turn off imidietly and buttery do nothing. ( Battery detected and charging well in os )

I tired all the smc and nvram and … reset.

Note. : It was fine before i just opened and clean it then this problem appear.

  • Magsafe light start with green then stay orange even without battery
  • Auto boot after plug the ac.

Update : this ic looks diffrent ( white buble inside ) ( check the target line in uploaded pic)

This buble mean the ic goes dead ?

When you opened it to clean, how/what were you cleaning. Did you take components out?

If the issue wasn't occurring before cleaning it out, sounds like something happened in the process.

OK you found the comparator resistors! And the one you pointed to R7006 has failed! This happens when you use a knockoff charger as they over power the circuit.
