Archived - iMac G5: Loose power cord could cause power loss

This article has been archived and is no longer updated by Apple.

To avoid a sudden loss of power, be sure that the power cord is fully inserted into the power cord receptacle on the back of your iMac G5. Loss of power occurs most often when you reposition the iMac, or if the power cord gets tugged. The ring on the power cord should sit flush with the back of the iMac case. Also be sure that the power cord isn't tangled with other cables or objects.

The pictures below show a correctly installed power cord and an incorrectly installed power cord.

If your iMac continues to experience a sudden loss of power and shuts down unexpectedly, try removing the cosmetic trim ring attached to the end of the power cord. The trim ring is circular and can be removed easily by holding the power cord as shown below, while gently pulling the trim ring away from the power connector. Once the trim ring works free, slide it down the power cord where it will be out of the way. The power cord trim ring is not necessary for iMac operation.
