When I'm finished using my computer for the while, I use [option]+[command]+[eject] to put it to sleep. Yesterday I noticed that nothing happened. So I hit it again. Again, nothing happened. As I pondered, the screen went black and it went to sleep. So I shut it down overnight figuring that it might work itself out with a reboot. This morning, there was about a ten second delay between keystroke and sleep. Do any Mac users have any thoughts? I suppose I can watch the action via Console.
Sleep is not immediate, because it takes time to write out a copy of RAM contents to disk. Next time you issue the sleep command [key sequence, apple-menu, close the lid, etc] listen very carefully to where your hard drive is. You'll hear it writing a *lot* of data for a while, after which it finally goes to sleep, and that can take up to 10 seconds or so. Depends on what you've been doing and how full memory is. . Look in your system log for an idea of all the thrashing the machine goes through on both sleep and wake. . I also recommend if you're going to sleep a machine to let it get fully to sleep mode [breathing] before waking it up again. Some people start the sleep sequence and then impulsively decide "oh, needed to do one more thing" and yank the lid open before things settle down. And then they wonder why their machines get into funny states sometimes. . It's also a bad idea to wake it up if it's been in the cold, before the temp of the drive equalizes to the room. Solid state drives will mitigate that problem once we get away from mechanical spindles, but in the meantime it pays to treat them gently. . _H*
Rebooting does sound PC-ish, but it is the simple way to turn off a misbehaving program that is eating up cpu cycles or gobbling up RAM. If you have a stable of programs you usually use, try to find one that might be the cause through a process of elimation.
1) The short form of perambulator, a wheeled conveyance for transporting infant humanoids. 2) Parameter Random Access Memory I'm guessing number two. Actually, on the newer Intel macs, it's called Non Volatile RAM. Here's an article from Apple support about it.
The Power Manager is an integrated circuit (computer chip) that is usually on the logic board of the PowerBook and iBook. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping. Over time, the settings in the Power Manager may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not seeing the AC Adapter, among others. Resetting the PMU is not intended for resolution of a stall or situation in which the computer is unresponsive. A PMU reset should not be necessary except as a last resort in cases where a hardware failure of the power management system is suspected. Performing a PMU reset returns the iBook and PowerBook hardware, including NVRAM, to default settings and forces the computer to shut down. For most situations, a restart is sufficient. If the computer has stopped responding, try these steps, in order, until the computer responds: Force Quit (Option-Command-Escape) Restart (Control-Command-Power) Force Shut Down (press the power button for 10 seconds)
Fortunately, it hasn't gotten that bad. And I think I have isolated the incident to "Weatherbug Mac" which is small and inconspicuous and I forgot was running. I closed Wb and sleep came more quickly. I haven't done detailed testing but I think I'm getting rid of the Weatherbug. Thanks, all, for your replies. I really am enjoying my venture into Macdom.
You're correct. I went to a Mac, and I have never gone back to it! I don't think it's been turned on in 5 months.
That's a shame. I'm sure you could find someone to take it off your hands, if you don't want it. It may as well be with someone who appreciates it.
