1 A1502 only works with battery disconnected
I’m struggling to figure out my GF’s Macbook issue. She had A1502 (Late 2013 Retina) and hardly uses it (occasional at home and music studio to play songs). One day it was used and carried back home but would not turn on anymore after return. After quick search, tried all the resets and then disconnected the battery. It was a changer as Macbook would boot with only charger connected and can boot once with battery connected but after shutdown, would not.
Symptoms.
- Only works with charger connected, does charge the battery, but would not work with battery connected to MB
- CPU seems like under-clocked running on charger, loads everything super slow and thinks too much
- I have tried to change the battery with iFixit kit, same issue, no change (anyone need spare battery?)
- Keyboard/touchpad works without flaw, all keys do work.
The only other thing I can think off is the motherboard but not willing to invest more money into unnecessary parts, would like to figure out solution. Keyboard replacement?
Update (09/12/2019)
FIXED: Keyboard was the culprit. Replaced with new OEM keyboard from eBay and all the problems disappeared. 3 hours to change though.

When the battery is removed your system will go into safe mode which is why your system is running sluggishly. The CPU's clock is reduced to protect the system from overheating.
At this point I'm suspecting your battery has failed until you get a new battery installed it will be hard to see if you also have other issues.

@danj thanks for the reply. I did change to the new battery but it had no effect on making it work as it should be.

What are the thoughts on replacing the keyboard for this as error code doesn't detect anything?
