Power Manager Reset

If you’re getting odd hardware errors with a Mac laptop, try the old voodoo trick of a power manager reset before you assume it has a mechanical fault. For instance, recently I started getting “Error Code 0x8002006E” when I tried to burn a DVD. This code is supposed to report a bad blank disc–but if you get the message no matter what you have in your drive, that obviously isn’t your problem.

The specific instructions for a power manager reset vary by model, but it involves turning off the machine, unplugging it and taking out the battery, and holding down a certain key combination for a few seconds. (On newer models, the secret key is mercifully just the power button.)

Here are step-by-step instructions for various models of:
68K Macs
PPC Macs
Intel Macs (note that the Power Manager is called the “System Manager” now)


I do get this error (0x8002006E) when trying to burn CDs and DVDs, unfortunately this happens on a Mac Mini (10.4.11), not a portable. Any suggestions what to do in this case?

Same brand of CD works fine on my Macbook (10.5), so I do not assume it is the CD that is causing the problem.

For just about any model disc burner, there will be certain brands of blank media that give it trouble. Since the Mac Mini most likely has a different model burner than the MacBook, try another brand of blanks.

Aside from that, isn’t the Mac Mini made from laptop parts? Even though it hasn’t got a battery, maybe following the (MacBook?) instructions for a power manager reset would accomplish something?
