hi there,
Got this macbook after liquid damage. Nothing major, cleaned and reflowed what was suspect. Now, the laptop turns on and boots up but shuts off intermittently - sometimes after a few minutes, sometimes after a few hours.
Can be immediately started from keyboard right after. Plug stays orange during this time. No battery.
Gives shutdown cause -128.
Seem to work fine in SMC bypass.
Same shutdown happens with disconnected TP/KB/KBLED/CAM.
Observations:
- SMC_RESET_L - when pulled down - plug goes orange/green and... -
History
- Got TV free. Prior owner claims Vizio logo shows up then nothing. He found U202 EEPROM replacement info (I know NickTV says its never EEPROM haha). Lifted 5 pads removing U202 without proper tools and thought thats end of main board. Gave the TV to me.
- I repaired U202 pads and connections. Soldered on prior owner purchased aftermarket EEPROM (original EEPROM was tossed). TV boots to VIZIO logo, then goes blank, shutsdown after a min or so and power on light blinks a number of times.
- Fixed 2 circa 2015 Vizios before with classical main board... -

Issue: Unit Powers On with Display Without HDD or ODD attached
When ODD or HDD is present unit powers on then Shutdown it reaches current of 1A that looks like want to boot but it will shutdown
Unit wont shutdown when ODD or hdd attach if no ram is attach also
I have tried flashing bios, the only different it will not shutdown immediately reaching 1A but eventually will shutdown also -
