[SOLVED]Strange power management after replaced isl6259 820-2936-A

[aurel476]

After replaced ISL6259 U7000 macbook works in good condition but when unplug magsafe status is power adapter bad solder at pin of ISL or short circut at the pin of U7000 ? How it possible

Pictures does not help...... Check sense resistors R7051 and R7052, better yet measure resistance between pins 17 and 18 from U7000

 

[aurel476]

Pin 17/18 of U7000 4,8 ohms
R7051 3,4 ohms
R7052 2 ohms

It means ACOK is not dropping down when you disconnect the charger. Probably bad soldered U7000

Yes it's good bad solder at U7000 solved thanks
