OS X / G4 fan doesn't sleep, light doesnt pulse

Message #1 - Posted 2001/10/26 - Fred Hickler

With my G4/OS 9, when the thing went to sleep, the screen would shut off, the disk would spin down, the fan would shut off and the power light would pulse on and off.

With OS 10.1, the monitor shuts off and the disk spins down, but the fan keeps going and the power light stays solid. The sleep still works as before when I boot up in 9.

Any suggestions?

Do you have any third-party PCI cards installed? My Dual 450 (100MHz bus) will spin down the disks but won't turn off the video or go into real sleep. I'm fairly sure it's because I have an Adaptec 2930 SCSI card is installed, although Adaptec's web site implies that this problem occurs only with the newer 133MHz G4s.

Well, based on your ssuggestion, I did a search on adaptec web site and came up with this:

  Question
  Is "Deep Sleep" supported by your SCSI cards in Mac OS X? This information applies to the following product(s): PowerDomain 2930, 29160, 29160N, 39160 PCI SCSI Card, AVA 2906 This information applies to the following Operating System(s): Mac OS X 10.0.4 or later, Mac OS X Server 10.0.4 or later   Answer
  No, as of the initial release of our Mac OS X drivers we are not "Deep Sleep" compatible. With the release of Mac OS X 10.1 we believe we now have the software and information needs to start developing support for this feature.

According to system profiler my scsi card is an adaptec 2930CU which i guess is the Powerdomain 2930 listed above.

Thanks for the clue...
