My iMac 2.8 goes to sleep randomly when I start typing.

The computer will wake up as I frantically hit the keys to wake it up, but it happens often enough to get very frustrating. Does anyone know how to fix this?

Thanks for the insight. I'm totally dreading a reinstall. I just bought a 1.5 TB hard drive to run Time Machine for a system back up. I'm wondering if this problem will carry over when I load Time Machine on the fresh reinstall and if it will work on a later version (10.6.1)?

  • Satellite A665-S5170 - display dim if goes to sleep or when i start up

    Hi, everytime my Satelitte A665-S5170 goes to sleep or when i start it up my screen resolution is very dim and the only thing that solves it is to recalibrate the display in color managment settings.
    Has anyone else had this problem?

    Hey,
    Can you change the display brightness by pressing FN+F6/F7 key combination?
    Im a little bit confused about this Dim resolution. Do you mean a low screen resolution or dim display brightness?
    If its related to screen resolution you could also try updating the display driver. Have a look on Toshiba website if you can find a newer version.

  • Macbook goes to sleep randomely when connected to Apple LED Display

    I have  an issue with my Macbook Pro (2009 model) when it's connected to my 27' Apple LED Display. For no apparent reason that I can tell, it just goes to sleep at random, and after I wake it up by pressing a key (bluetooth keyboard), the mouse cursor looks messed up:
    It might be a bit hard to tell from the blurry photo (I don't know of a way to take a screenshot with the cursor, so I used my iPhone), but it's too halves of the spinning beachball.
    There's nothing in the console's log that indicates the reason for switching to sleep mode. It's also not the magnets of the Macbook pro used to detected when the lid is closed (I'm using the NoSleep utility that prevents that behavior). I've already tried resetting the PRAM. Also, this behavior never happens when the macbook isn't connected to the external display, so that probably aint a heating problem either (also the temperature readings are all in bounds).
    Any help would be very appreciated, as that thing is driving me crazy.

    Jon,
    Along the lines of my comment in your other thread. The battery connection cable between the logic board and the battery is also known as the "sleep/switch" connector. This little cable not only communicates battery power to & from the machine but also has a handle on regulating the machine's sleep process (and wake from sleep).
    I've seen several MacBooks that have come across my work bench which are suffering from this exact issue you're describing and we're remedied by replacing that cable.
    The component I'm referring to is this one-

  • My new Mac Air continues to disconnect from WiFi after going to sleep.  When waking it up I have to manually re-connect.  How do I keep it connected?

    My new Mac Air continues to disconnect from WiFi after going to sleep.  When waking it up I have to manually re-connect.  How do I keep it connected?

    I had this problem too and solved it by doing a clean install. After that it was gone.
    This is a drastic method since it takes quite some time to reinstall lion and all your software.
    Thoughts I had why it started working after a clean install are the following:
    It looked like the airport wasn't able to reconnect fast enough before the connection timed out. So what could have prevented my mac from being able to connect fast enough?
    Apps that consume processor cycles. I love what I would call 'System Enhancers', little apps that enhance my workflow (Moom, Alfred, Dropbox, Default Folder etc). I'm not saying that these are the problem, they might be programmed processor friendly, but check if you have apps that consume processor cylcles. It might prevent airport from being able to reconnect quickly enough before it times out.
    Mobile Config profiles. Another thought I had was that I had a mobile config 802.1X profile installed for the company were I worked. It used TTLS to connect to the corporate network. This profile might have gotten in the way.
    And a sidenote...
    Routers with hardware acceleration might also be a problem. My router is a Wireless Gigabit Router 300N WL-351 and has hardware acceleration. As soon as I activate that my wifi connection keeps dropping. It is as if a Macbook Air can't handle that amount of optimisation.
    That's it, hope it helps those who are still having the problem.
    Best, Jan

  • My macbook goes into 'sleep' mode when my mobile runs over the bottom left corner, next to the trackpad, does anyone else have this problem?

    Not sure if anyone else has this problem. I only noticed it a few weeks ago when I left my mobile on the keyboard, towards the left of the trackpad. When I started typing I accidentally nudged my phone off the board and then everything went black. I hit any button and everything turned back on again. I'll assume that it went into 'sleep' mode. Is this normal or should I be worried about the health of my mac?

    I am facing pretty much the same problem ... although sometimes the click does work on other parts of the trackpad, but largely I have to stay focused on the left bottom corner. It's getting slightly frustrating esp. because I like the click better than the "tap" and my MAC is only a month old!!
    Is this a software issue or a h/w problem?

  • How do I disable the simplify awesome toolbar? (when i start typing it goes to the address bar instead of where I put the cursor)

    When I am in Gmail or most other sites, when I type it automatically goes to the address bar. For example, in Gmail, I will click reply, and the cursor starts flashing in the message box. However, when I start typing, it goes into the address bar instead. When I am on another website (for example I am on my library website), i place my cursor in a field, start typing, and again it goes in the address bar. I have tried disabling the add-on, but it doesn't appear in the list of add-ons. When I search, I have the option of installing, as if I don't already have it. Any suggestions would be helpful!

    Hi,
    There are a few keyboard shortcuts that jumps to the awesome (location) bar. Please see [https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly?redirectlocale=en-US&redirectslug=Keyboard+shortcuts#w_miscellaneous this]. You can try to check if any keys are stuck.
    If keyboard problems can be ruled out, you can also Reset Firefox.
    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.

  • Imac no longer going to sleeping after update on July 8, 2014

    just did the latest update on this week to 10.9.4 Build 13E28 on my iMac 2.5GHz Intel Core i5 and now my iMac well not go to sleep on its own.
    have already reset SMC
    pulled the com.apple.PowerManagement.plist
    reset PRAM
    reset power setting in system Preference panel
    anyone else having this issue? my system was working perfect before this update..
    really don't want to wipe and rebuild my system at this point.

    Test after each of the following steps that you haven’t already tried:
    Step 1
    Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer  will not sleep if Internet Sharing is enabled.
    Step 2
    From the menu bar, select
               ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
    Step 3
    Select
               ▹ System Preferences ▹ Bluetooth ▹ Advanced...
    and uncheck both boxes marked
              Open Bluetooth Setup Assistant at startup if...
    Step 4
    Reset the SMC.
    Step 5
    Disconnect all wired peripherals and test. If you use a wired keyboard and/or mouse, use different ones. You must rule out the wired keyboard and mouse as possible causes of the problem.
    Step 6
    Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Safe mode is much slower to start and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
    If sleep now works as expected, go on to the next step.
    Step 7
    Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
    Step 8
    If sleep is still working after you’ve launched all the usual applications, restart as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
    If you still have the sleep issue after restarting out of safe mode, post again.

  • IBook G4 goes to sleep randomly

    My iBook G4 was running fine until I replaced the optical drive. I went from a combo to a superdrive (UJ825). After installing and reassembling the iBook it boots and then goes to sleep. I can wake it up but it goes back to sleep again after about 1 minute. I am confident in my work as I did the hdd upgrade and had no problems. Any clues? I also tried a reinstall of the OS and ended with the same result.

    Hey Keith,
    This is the switch that rests on top of the optical drive, correct?
    Right, the manual shows it on the front right corner of the drive.
    Should it be on the frame?
    No I think you have it right. Originally I was looking at a totally taken apart 1.33 12" but I just looked at the manual.
    Did you try disconnecting that cable? That would disable the reed switch and test if it was bad. The action can be checked by using a magnet over where the switch lies.

  • HT1338 My macbook pro goes to sleep randomly and only wakes up when i tilt it

    I bought my new macbook pro last june in miami and somehow it just goes to sleep on its own in the middle of doing anything.
    Clicking, pressing the start button, the space bar or anything won't wake it up. Tilting it or lifting the computer would. And that's scaring me. It just did it 4 times in a row and i am just browsing the web
    Anyone know if this is a hardware thing or the software is going nuts or my mac is haunted ??
    I have the mac insurance thingy so should i call them or what do i do? Thanks for the help

    Check your current setup (I left my MBP as "3")
    go to Utilities > Terminal
    After you launch Terminal, the first step is to determine which sleep mode your Mac is currently using. You can both view and change the sleep mode using the Unix program pmset. To see your current settings, type (or, copy and paste)
    pmset -g | grep hibernatemode
    press 'enter'
    You should see something like this:
    $ pmset -g | grep hibernatemode
    hibernatemode 3
    Great, so your machine is using mode 3, whatever that might be. Well, thanks to the documentation for the handy Deep Sleep Dashboard widget, which puts your machine immediately into hibernation mode (so you don’t have to yank all the power sources to invoke it), we can tell exactly which mode is which:
    * 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
    * 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
    * 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
    also, I enabled this:
    go to Utilities > Terminal
    type in sudo pmset lidwake 0 then "enter"
    it will ask for your password. type it in, that's it!
    Now, when your computer is sleeping with the lid closed, when you open the lid nothing happens until you press any key ... nice: keeps it off when accidentally opened, like in a backpack?
    WARNING: Improper use of the sudo command could lead to data loss
    or the deletion of important system files. Please double-check your
    typing when using sudo. Type "man sudo" for more information.
    To proceed, enter your password, or type Ctrl-C to abort.

  • IMac acting strange... restarts randomly, difficult to start...

    My iMac has been acting very weird lately.
    It started with random restarts when I was not even standing by the computer. It has been freezing frequently also.
    Lately it has restarted and I heard the initial start up noise for a quick second and than it restarted again. This happened about 20 times before the computer actually booted.
    If anyone else is having these problems please let me know. I have no idea whats going on :S

    Hello Philip
    Reset your iMac's SMC (System Management Controller) exactly as described in the "how to" link below.
    http://docs.info.apple.com/article.html?artnum=303446-en
    Then if you are still have a power issue, you should take it in for service.
