I don't have a second MacBook. Is there an option without additional hardware?Leave a comment:

I don't know how it happened, but it only works on battery. Maybe it required an SMC reset. After starting it up and entering passwords, it freezes and the touchbar doesn't light up.Leave a comment:

MacBook A1990 — No Display With Battery Connected
Hi, I have a problem with MACBOOK A1990 - The laptop starts with no image when the battery is connected, but without the battery it starts with an image - however, when using only the power supply, when logging into the system it turns off and resets again.
Battery replaced with another unit → same problem.
ISL9239 replaced → no change.
SMBUS_BATT_SCL / SDA measure ~20-50kΩ to GND with battery disconnected (normal).
Any ideas or advice would be a huge help!
Thanks in advance for your time. -
