New Battery Is Charging & Recognized, Won't Run on Battery

Just replaced the battery in the MacBook Pro 13” with a new one from iFixIt. The battery shows up at 78% and is charging, I’m watching the mAh increase. The LED on the charger shows orange, as in charging. If I disconnect the power supply the computer won’t run on the battery alone, it must be plugged in, even though it has a charge. Any ideas?

Thanks Dan, I uploaded that.

Well the battery does appear to be in good condition as you implied.

So that part of the circuit is working so if you now pulled the MagSafe connection he system would just shutdown on its own in a few seconds. Is that correct?

@danj Right, if you pull the MagSafe it powers off immediately. Battery has charged all the way up now thouhg.

Sadly, I think the switching logic which control the power source from the battery to the logic board is not working.

It’s going to take someone with deep circuit diagnosis and access to the needed schematics and replacement parts.

这个答案有帮助吗?
