Dear team, i have problem i start hardware test and find this error.What should need to do?
MacBook Air, OS X Yosemite (10.10.3)
Make an appointment at an Apple store genius bar for a FREE evaluation. Your MBA has a power bus voltage problem. This is a hardware issue with no software solution.
Ciao.
Connect its power adapter, and run Apple Hardware Test again.
After smc resset 3 or 4 times in one time. And connect power adapter
I start full test and nothing all is ok
So this is a problem?

No. That particular code will normally appear if the power adapter is disconnected when you run AHT. Your Mac is fine.
So it is a error of not connected power adapter?😕
I would more accurately describe it as a bug in Apple Hardware Test.
