Same issue is occurring with F5200 removed. C5250 voltage goes to 12.30v then drops to 0V while magsafe or usb-c is plugged in as they go off and come back on
This arrived with no liquid damage. Power cycles every few seconds. Board looks pristine. Checked all coils and do not see any shorts.
When magsafe or usb-c is plugged in they both turn on for two seconds then off then on. All voltages appear as well.
What should be checked next?
This arrived with fans spinning fast and slowness. Replaced Q5852-Q5854 but no change. What should be checked next and which program is recommended to find which sensor is at fault. Trackpad works as fine
Arrived with a burnt CD3217 and usbc amp meter going on and off every few seconds. Second port stays on at 5v
Replaced bad CD3217 from a donar M1 board but same issue. What should be checked next?
To save trouble of replacing U8600 would the data be readable or even boot into the OS if U9120/U9200/U9100 were moved and soldered to a working 820-00923 board since these have the T1 chip?
Trying to replace U8600 pad 315 PP1V8_SSD_HOT is missing however all other pads are present after cleanup. Will replacement U8600 still work for data recovery with this pad missing?
