Asleep at the Wheel -- A number of folks commented last week that you can approximate some of the sleep features in the new PCI Power Macs with Sleeper, a $20 shareware control panel from St. Clair Software. Sleeper blanks your monitors and spins down your hard disks, but it does not power down Energy Star monitors. I'm pleased that Apple has done what they have with the new Power Macs, but even still, to me, a sleep mode should work like the one in the PowerBooks does. I want the entire machine down and silent - no moving parts at all - but the Mac should be able to wake up exactly where it left off. I realize that may not be technically possible with the existing chips and system design, but if PowerBooks can do it... [ACE]
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
