    My G4/450DP running 10.2.6 will deep-sleep if I press the power button
    or if I select Sleep from the Apple menu, but if I just let it sit
    there for 30-60 minutes, it only goes into light sleep (e.g. screen
    goes dark and drives spin down, but the fans stay on).

    I checked my Energy Saver settings, and "Separate sleep" and "Spin
    down HDs" are both un-checked.

    Anything else to look at? Thanks!

  2. Certain (actually many) older PCI cards will interfere with deep sleep.
    SCSI cards, video cards, etc. xlr8yourmac.com trys to keep track of some
    of them, and is a good place to get familiar with the issue.

    Also, some hubs and other peripherals can interfere with deep sleep. Try
    this: strip the machine back to stock, set sleep to 1 minute, then start
    adding back devices until you find the culprit.

  3. MY DP450 has the same problem that Steve Kan's DP450 has. I had an
    Adaptac 2930 SCSI board installed that I quit using when I replaced my
    Jaz and Syquest SCSI drives by a Firewire CD burner. So I removed the
    SCSI board and any file that had Adaptec in its name. Same old problem.

    Are their other files witaout Adaptec in their name, which were
    necessary for proper Adaptec 2930 operation that I could now remove?

  4. Actually, the latest drivers should allow deep sleep with the 2930. I
    have a 2930 in my Dual 1 GHz and deep sleep works fine. Regardless, once
    you pull the card the drivers won't load, so that is not your problem.
