White log in rectangle remains on my screen despite Imac sleep

Discussion in 'Apple' started by Robert Montgomery, Sep 30, 2011.

  1. Sometimes the while log in rectangle remains on the center of my screen,
    even when the Imac remains asleep.

    How can I avoid this problem?

    Even when I use Hot Corners to activate the screen saver, about five
    seconds later, the white login rectangle appears on the screen, with the
    fields for my user name and passcode.

    if the mac is sleeping, there can be *nothing* on the screen, as it's
    not powered at all. it's basically off (but memory is maintained).

    if you put the mac to sleep and the box appears, then something woke it
    back up, or it wasn't sleeping like you thought it was, i.e., it could
    be just the screen saver, not sleep.

    some apps will prevent the mac from sleeping or the screen saver from
    one or more apps you have running is causing it to appear, or your
    mouse is sending data and activating it, even if it's not moving. i've
    seen this happen with third party mice but not apple mice.

  3. Thanks, NoSpam.

    The program appears to have been caused ins Safari – maybe because of a
    paused video in Safari.

    I just quit Itunes and Safari. Then I used Hot Corners to put the Imac
    to sleep. The white rectangle didn't reappear.

  4. You could complete the login, then sleep it. Actively put it to sleep,
    not just let the screen saver come on before it eventually sleeps itself.

    Possibly not related, but I noticed that if I put the Macbook to sleep,
    and then turn off the bluetooth mouse, the macbook wakes up.

    That's normal. A few ways to avoid it:

    Leave the mouse on. When the computer sleeps the mouse LED should be
    off, so it won't use much battery power. It takes a click, not just a
    move, to wake the computer.

    Turn the mouse off before you put the computer to sleep.
    Command-Option-Eject can be used for Sleep.

    Use the Advanced button in Bluetooth system preference and disable
    waking via Bluetooth.

    I should have mentioned that I discovered that eventually.
    Still, I think that is a design error. Turning one OFF
    should not constitute a wake-up call.
    I think after you put your vibrator away, you should wait an hour
    for your mind to clear before posting. And don't set it on the
    table, as it takes very little mouse movement to wake the computer.

    Have you got "Allow Bluetooth devices to wake this computer"
    ticked in Sys Prefs?

    If not, does it happen when you switch your mouse off or take the
    batteries out when a few feet away and not in vibrating contact
    with the MB?

    To turn a mouse off, don't you have to handle it? Does not
    handling it risk moving it and triggering the wake up?
    My mentioning the possibility of vibrations from handling your
    blue tooth mouse near the Macbook and possibly any other
    connected usb device like an external keyboard is an excuse for
    you to be rude to me? That is a surprise coming from you Wes,
    perhaps you are thinking that talking to me should be balanced by
    some ill manners on your part. Perhaps you are not beyond
    disgracefully wanting brownie points from TBG? Shame on you!

    I made a joke based on a misunderstanding of what you said.

    Since it is you, I have no way of knowing whether the original
    comment was a joke or not, nor whether you are serious about
    thinking it rude.

    In those respects, we are similar.

    But what is a TBG and how does it differ from a TBD ?

    It is not joking to suppose that movement of a laptop and any
    attached USB devices like keyboards or mice (yes, I have had a
    usb mouse connected as well as mainly using my bluetooth one)
    needs to be avoided.

    Something you are not addressing: it seems simply extraordinary
    to me that you would suppose turning off a mouse would not
    trigger wake - if you have the wake pref ticked (have you given
    an *unequivocal* answer about whether you do have this ticked?) -
    since you need to touch the mouse to do it?

    Perhaps you have a second order Bluetooth connection to your
    Bluetooth mouse to turn it off without touching it? Or do it by
    ESP? By looking at the Bluetooth a certain fierce way to frighten
    it off?
