scheckler21 Level 1 Level 1

First, I have a 2.0ghz CD Macbook with 1GB RAM. I recently did an erase and install update to Leopard. Since then, I have not been able to get the computer to put itself to sleep. I can manually tell it to sleep or shut the lid and that works, but it won't auto sleep.

I have tried:
-deleting all HP files
-Resetting SMC
-Disc utility stuff

Nothing has fixed the problem so far.

Here is the weird part:

If I restart the computer with the ethernet cable unplugged, the computer will sleep fine. If, at any time, I plug in the ethernet cable, the computer will not sleep...even if I then unplug the ethernet cable. I really don't feel like making a launch daemon to solve the problem and I don't feel like downloading third party software to fix the problem.

Basically I'm just afraid that the hard drive is getting unnecessary wear and my battery life is terrible if the laptop is left open and not charging. I'd be perfectly happy to hear that this is an OS problem and will be fixed next update.

Please help! Thanks!

Macbook, Mac OS X (10.5.3)

    I have had a problem with auto sleep, which stopped working under 10.5.2. The computer will manually sleep whenever I want it to, but it won't auto sleep at all.

    I was expecting the 10.5.3 update to fix this (it is fairly evidently a problem affecting several users from the various forums which mention it), but it hasn't.

    Can anyone help please?

    Having the same problem. Just happened since 5.2. 5.3 did not fix it.

    No auto-sleep here (other sleep methods working fine). 10.5.3 has been running on the MacBook (and the MacPro, also experiencing the no auto-sleep issue) since purchasing.

    With both of my machines having the same problem, it's either some software I am running on both, or OS X itself. Find it hard to believe I bought two computers with hardware issues that are exactly the same on two different types of machines. Other than sleep issues, both seem to be working great.

    Ditto here. No auto sleep.

    I think my issue started when I switched from Apple wireless Mighty Mouse to a M$ bluetooth mouse.

    I'm all Apple here, wired mouse. And the MacBook shows the same issues with no peripherals attached.

    It's both situations with my MBP. Sometimes goes in auto-sleep (set to 1.5h on Power) when I leave my desk for a long period. But last night, I started the "publish" new thingy of Delicious Library 2 and went to bed. On the morning, the MBP was still up.

    I guess there are some applications that keep "on" some functions that make the auto-sleep feature believe the Mac requires to stay up and thus cancels auto-sleep. I don't know the specs for this part. Someone here can get you with additional details if required.

    --> Anyways, to the attention of 'scheckler': Don't be afraid letting your Mac on all the time. It's a machine, not a hurdles runner.

    A machine, like a hard-drive, is getting more wear by the warm-cool-warm cycles than staying up and warm all day long. The HD protects itself, by parking during long periods of inctivity.

    Your Mac won't get super-hot during the night because nearly nothing happens besides the daily cron'ed jobs (launchd now).

    I personally put my MBP to sleep only to carry it around. My other non-portable machines are up 24/7 (and on UPS).

    Has anyone had any issues with the sleep function when the power adapter is not plugged in? Since I upgraded to Leopard when ever my macbook is on battery power after about 30 min or at around 50-60% power the macbook abruptly shuts off as if it was a desktop having the power cable unplugged. Prior to leopard the macbook would just automatically put it's self to sleep at about 5% power.

    I had a similar issue with my original MacBook. Have you tried conditioning the battery? Not sure about exact steps, but I believe you let it run down on battery, then charge to full capacity and then some for a set amount of time.

    I ended up getting a replacement battery from Apple under warranty though. Problem went away after that.

    I have discovered that the outgoing network activity monitoring utility Little Snitch was the cause of my problems. Once I disabled it, the MacBook went to sleep normally under Energy Saver settings.

    I dropped a line to the developer on this, but have yet to hear back.

    I just want to warm this thread up again.

    During my iMac & Leopard career I randomly recognized various auto sleep problems.
    With start of 2009 the problems begin to get bigger. The auto sleep mode only works very randomly now.

    I already looked for disturbing processes, reinstalled the 10.5.6 Combo Update, checked the console messages. But still I have no real solution.

    As many other users I am also able to start the sleep mode manulally but the auto sleep mode seems to be not very reproducable.

    Solution: *Reinstall OSX on cleaned and initialized disk (or use another disk that is Vanilla install)* must be a clean Install.

    Unhook all USB Firewire except for Keyboard Mouse.

    Sleep should work fine. Start adding back your extras when you Loose sleep you have found the culprit. I stay Vanilla as much as possible . I found I could not install Office 2008 or I would loose sleep! YMMV.

    But I have prefect auto- sleep after all that heartache. Best to you!
