Question about Apple iMac G5 Desktop
Received an error message in Apple Service Diagnostic - Ambient Temperature error -25128
so I replaced the HD temperature sensor and cable but still get the same error when I run Apple Service Diagnostic again. The Hard Disk Temp.Sensor does not show up in Temperature Monitor or iStat. Computer behaving well mostly but sometimes will not startup, stays on black screen with front light on.
iMac G5 20" PPC 1.8 ghz V.1 2005
There is more than one sensor in the unit, the other two are part of the logic board and can't be changed unless the logic board is changed.
