  • Why does my PowerBook sometimes not wake up from sleeping?

    It's rare but sometimes after my 'puter sleeps it won't wake up normally. I have to restart it with commandcontrolpower. Other than that, everything seems fine. Any ideas?

  • Why does my macbook Pro pinwheel after reopening from sleep?

              I have a 2.4 i5 MBP with 8GB Ram running 10.6.7.  It is attached to my work exchange server with authenicates my login and network. 
    My problem is that often, but not always, when i reopen the lid of my MBP awaking it from an overnight sleep, programs are unresponsive and even basic finder/OS functions are not available, like force quit or system preferences.  The pinwheel usually starts when I click the wifi icon in the top bar.  The only way out of this is to hard reset the machine.  Today I had to hard reset it twice because even after a reboot the machine was unresponsive for a long period of time. (20 minutes maybe).
    Could this be an exchange problem?  I never have trouble connecting to the exchange while the computer is awake, and i am connected to the ethernet and wifi.
    Help!  If I go to the IT guy he'll just want to wipe my mahcine rather than troubleshoot.

    Shutdown the machine nightly instead of using sleep.
    Try running all of OnyX cleaning and maintenance features and rebooting.

    Also use the Verify Preferences (check show only corrupted plist) and make  a not of which ones are bad, seek and move these to the desktop and reboot, they will automatically rebuild.
    If everythign is fine, then move the bad plists to the Trash and empty.

  • My MacBook pro wont wake up from sleep. The screen is blank at all times, but I can hear the fan for 5 sec then everything stops. Please help! I don't kno what to do.

    My MacBook pro is about 3 yrs old. It is a 2008 model right before the new design came out. Recently I closed it up which puts it to sleep and a couple minutes later when I opened it up the screen stayed blank but could hear the fan running but then the power clicked like it was shutting down and I could hear nothing more. My power supply is working and I have already tried resetting it. Can anyone help me? I don't live exactly near a Mac store to get help.

    Before resorting to an LB change-out, try this, as it has fixed many of the "silver-key" Macbook Pros with wake-from-sleep issues:
    1) To get the computer running, do an SMC reset. Instructions here:
    http://support.apple.com/kb/HT3964
    Your MBP model uses the first option under the subhead, "Resetting the System Management Controller (SMC)"
    2) If you get it running, go to System Preferences > Network and select your Airport connection
    3) In the result main pane, click the "Advanced..." button.
    4) You should be looking at a window with multiple tabs at the top; the "Airport" tab (far left) should be active---if not, make it so.
    5) There is a panel showing "Prefered Networks." Use the "minus" button below that window to eliminate any networks that you don't need to access on more than a weekly basis. I'm down to two: the home Airport Extreme Base Station and the network for a museum at which I volunteer once a week.
    5) Click "OK" and close System Preferences.
    Now try letting it sleep and see it if wakes up.
    When this happened to my Late 2007 MBP, I used Console to read system.log and found that, on waking, the compuer was looking for the wireless network at a lodge where I'd stayed weeks earlier and miles away. Clear the morass of old networks and keeping the list short has completely cured my wake-from-sleep issues.
    The steps I listed take less time to do than to read, and are within the ability even of novice Mac users.
    If that doesn't work, you may need to seek professional help. If you take it to an Apple Store and they recommend a logic board replacement, ask about a "Depot Repair." Instead of replacing the logic board on-site (which will whack you to the tune of US$700-1100), they send the computer to a central Apple refurb facility that fixes whatever they find wrong for a flat fee of about US$315 (last time someone reported using the service here). Turnaround is about one working week, and people who have taken of this service have reported being very pleased with the outcome.

  • Why does my MacBook Pro not boot up with the Snow Leopard Disk?

    I have erased the entire hard drive on a 2011 macbook pro that had snow leopard on it. I was corrupted. I not insert my Snow Leopard Disk and the machine will not boot. I chose target mode to erase the hard drive from my mac book pro with Mt. Lion on it.
    Thank uou for any help,
    Ken

    Target mode?  Is there a second computer involved?  Why not insert the Snow Leopard disc in the computer on which you wish to install and hold down the C key to boot from it?
    If the disc came with a different computer it will not boot another model.  Retail discs also may not boot all model computers, even those that came with the same major version.  For example, some MBPs came with 10.6.6 but a retail disc may only be 10.6.3.

  • Why does my macbook pro not start up?

    Today I changed ram on my old macbook pro. 667hz DDR2 type from 2X1 TO 2X2.
    After i finished the installation my laptop has not worked properly. It currently runs 10.7.
    No startup sound, and the white light at the bottom flashes constantly in sequenses of three. Three quick flashes.
    What is wrong? Even when I re-inserted my old RAM the same problem occurred.
    Please help!

    MacBook Pro 3,1  15' 2,2 Core 2 Duo Late 2007.
    I used the same buss speed (667 mhz) and the same type DDR2. Same number of pins.
    I also checked what happened with 0 ram in slots, and then it started blinking constantly.
    So it must see the RAM but the RAM seems useless for some reason...

  • Why does my macbook pro not have an apperance tab under display

    I am trying to connect my macbook pro to my tv to watch Netflix via an adapter and HDMI cable.  I went into Display to go to Appearance and turn on mirroring but I don't have an appearance tab under display.  Is there somewhere else this would be?

    Thank you very much but now I have another question.  I plugged in my adapter to my computer, plugged the adapter into the HDMI cable, plugged the HDMI Cable to my TV. I have tried the Detect displays button after I changed my TV to the HDMI source and Before I changed my TV but I still can't get my computer to detect any displays.  Do you happen to have any suggestions?

  • Macbook Pro Screen wakes up from sleep without any acitvity

    I've set my MacBook Pro screen to turn off after two minutes of activity. I've had this setting for all my Macs and I've never had any problems.
    Recently though, my MacBook Pro's screen turns on by itself without me touching the computer or any mouse attached to it. What could be the problem?
    It's really annoying when the screen turns on at night.
    Any help will be appreciated.

    I have the same problem. I brought up console and there is nothing at the same time as the screen turning on. My situation is as follows:
    I put on a podcast. The only applications running are firefox and iTunes. I turn the screen brightness all the way down with the F1 key, then mouse over the corner of the screen set to turn the monitor off.
    After about 6 minutes, the screen comes back on at brightness level 1. If I touch a button or the trackpad the screen turns back off. It stays off for about 6 more minutes and does it again.
    Edit: I just checked the logs with all showing and the only thing I see is a Wake Reason = EC LID0.
    Any tips?

  • Macbook Pro not always waking from sleep

    The only time I sleep my Macbook Pro is when I close the cover. Before I open it, I make sure that the light on the front is pulsating, indicating it is fully asleep.
    Sometimes when I open it is is waking up fine, and other times the screen just stays black and the light on the front remains pulsating. When the screen is black, pressing the power button or shutting the screen and opening it again has no effect - the only thing I can do is hold down the power button for 10 seconds and restart my computer.
    This only recently started happening. I'm running 10.5.4, but it started happening with 10.5.3, although I don't think it's system related because it didn't start right after I upgraded to 10.5.3 but some time after, only about 2 weeks ago from today.
    Any help on this matter would be appreciated!

    if you do a search, you will find other threads related to the sleep issue, and might find some insight there . . .
    it is strange, i was having the problem too, where the sleep problem would happen intermittently. after i realized there was a problem i stopped putting my mbp to sleep. but recently i have started to use the sleep mode for my mbp, and have not had this problem again.
    have you consulted with apple on your issue?

  • April 2006 macbook pro core2duo wakes up from sleep with in sleeve

    The title pretty much sums it up, The past couple of days I've gotten home from work and my macbook pro will have the screen on, and running. I have no open programs, I have reset the pram and the cmu to no avail. This really concerns me, I'm wondering if anyone has any insight. I made an appointment at the genius bar tomorrow, but I know that the problem won't be able to replicate when I get there. Just seeing if anyone else has encountered this.
    Thanks

    Welcome to Apple Discussions!
    There are a couple of things to check.
    First, be sure the Mac is truly asleep before you put it in the sleeve.
    Second, be sure the latch is working properly. If the lid pops open because the latch pops loose, the Mac could wake up.
    Otherwise, good luck at the Genius bar.

  • Leopard: MacBook Pro rarely wakes up from sleep

    Hey all,
    I just installed Leopard last weekend, and have noticed that at least half the time when i shut the lid and put my computer to sleep that it will not wake up when i re-open it. it is not an issue of power supply because this happens when i have the computer charged decently and even plugged in.
    any suggestions?
    thanks a lot

    Same problem here. Of course Apple support is vacant on this issue. I think its time for Consumerist. This issue has been posted dozens of times with no response from Apple. Other options are if you purchased with American Express you could probably get them to force a repair/replace.

  • Why does my MacBook Pro not find USB hard drive after waking from sleep?

    is this a known issue? i have to manually turn off/on the Mac's Airport to re-establish USB HD connection (or Time Machine won't find it either).

    I hate to have to tell you this, but backing-up that way is "iffy" and *+not supported by Apple.+* See [Using Time Machine with an Airport Extreme Air Disk|http://web.me.com/pondini/Time_Machine/Airport.html] (or use the link in *User Tips* at the top of this forum).
    It sounds like you're using that disk for other things besides your backups; if so, and if you're going to continue backing-up that way, it really should be partitioned so Time Machine has it's own, exclusive space. See #Q1 in the same link.
    Time Machine should find it's partition when OSX wakes up; if it doesn't, try a "full reset" of Time Machine, per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).

  • Why does my macbook pro not discover a bluetooth headset?

    I have a Philips SHB6110 bluetooth headset. I went to the place where you can set up a new bluetooth device, but it does not show the device on the list.
    The headset is on and charged.
    Any answers?

    Hello sig,
    I don't think, that you completely understood my question. The problem in your question, is that there is something wrong with the sound output/input, but my problem is, that my headphones will not pair or even be discovered by my computer.
    However, during the time, that it took to get the first answer on here, I found it out myself.
    While pairing, your headset must be in a so called "pairing mode" you can get it by switching your headset off, then holding the power button until the LED starts blinking red and blue. Then your mac should discover it without a problem.
    The audio quality is quite bad on this headset, so I will only be using it for skype. It's really weird to listen to music on these.
    All the best,

  • Why does my macbook pro "goes to sleep" when charging?

    Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
    I read from threads that it is a logic board problem....How do I solve this problem?

    Try an SMC reset. Follow the method for "a battery you should not remove yourself."

  • Why does my MacBook Pro and Mac Pro keep freezing?

    Why does my MacBook Pro freeze?
    MacBook Pro
    2.4 GHz intel Core2 Duo
    4BB 1067 MHz DDR3
    OSX 10.6.8 Snow Leopard
    I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
    Tried safe boot several times. No help.
    Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something  - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
    Couldn't clear cache etc as couldn't get to the relevant part to do it.
    Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said  “The volume appears to be OK”. No help.
    Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
    Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
    Cheers

    ... does Apple products work much better with using Apple routers?
    While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
    Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
    If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.
