DV8T Fan grinding sound when opening lid or returning from sleep mode

I don't know if this is a normal thing, but not always, Id say 50% of the time when the computer wakes or I open the lid there is a breif grinding sound coming from the top left area of the body of the notebook. I am pretty sure it is the fan and im wondering if this is going to eventually lead to a ballance issure with the fan causing it to fail and ultimatly kill the CPU.

I'm having a similar problem that I may have cracked. My screen is on but the backlight is off (so the image is practically 100% on resume from hibernate. Have you reset the pram and cleared the smc?

  • Short flickering when the notebook wakes up from sleep mode MacBook Pro Late 2013

    Hello everyone!
    I have a question concerning the display of my new MacBook Pro with retina display (late 2013).
    Sometimes when opening the lid when the notebook wakes up from sleep mode, the display is flickering for like two seconds. Then everything is normal again.
    This specially occurs when the lid has been closed for a longer time. It makes no difference if the power adapter is plugged in or not.
    Have you experienced a similar flickering with your MacBook Pro?
    Thank you in advance!

    Hello!
    I have the same problem with my late 2012 MacBook Pro Retina. The constant flickering after being awoken from sleep was a minor annoyance for me so I contacted Apple Support.
    I shall explain what I have done thus far, and I recommend you follow the same steps as I did to tick off possible causes:
    Firstly, I reset my PRAM (http://support.apple.com/kb/ph14222) and SMC (ttp://support.apple.com/kb/ht3964).
    The issue still remained so I checked if the flickering occurred in a new user (if it does not then it points to your account having a setting which is causing the flickering - possibly third party). For me the flickering continued so I tested it in Safe Boot (which worked fine!).
    I then ran (just to be certain) the Apple Hardware Test (http://support.apple.com/kb/ht1509). All seemed to be OK. So I reinstalled OS X and still the issue remained.
    It was then I had an Apple Support person 'screen share' with me and we went through certain folders. My GPU folder had an unusual amount of files so we trashed them and began a restart however this led to a bigger problem; my notebook wouldn't boot (not even in Safe Boot!), so be very weary at this stage, I'm not sure if this was a rare case or we deleted something we shouldn't have. I then had to go into recovery mode to get back to square one.
    Back to the initial problem I reinstalled a 'clean' OS X version from recovery mode; this was to determine whether if the data is corrupted on my account or if it's something else; most likely hardware by now even if there was nothing that came up in the hardware test (it won't account for everything). I checked from both a backup of my data and then from a fresh user after reinstalling OS X and still the flickering continued.
    It was then a Senior Apple Support person set up an appointment to have my MacBook looked at and possibly repaired (it could be a minor wire causing the problem).
    That is the point I am at now, so for my case it seems like a minor hardware problem. If your case is as similar as mine I recommend making an appointment with them to run more sophisticated hardware tests that your own MacBook would not run.
    I will comment again when my issue is completely resolved for those who come across this Discussion in the future.
    Hope this helps!

  • When trying to log back from sleep mode, the screen behaves as a rotating cube, with the mouse pointer in the top left corner. Hangs.

    iMac OS X Ver 10.7.3
    21.5 Inch, Mid 2011
    2.5 FHz intel Core 5
    12 GB 1333 MHz DDR3
    When the computer in woken from sleep mode we see two login options (bineg used by two users).
    But when we try to login, the screen just behaves as a sluggish rotating cube.
    Nothing works, we just have to hard boot at this time.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    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.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • My ipad doesn't seem to make a sound when it is closed or in sleep mode to let me know there is an imessage until you see it on the screen that someone has imessaged.  When you're taking it makes the swoosh sound, just not when it's in sleep mode.  Help

    Am having some problems with the sounds on my ipad, specifically my imessage notification sound when your ipad is in sleep mode and someone is messaging you.  It seems to work with the swoosh sounds when you are actively messaging back and forth, but as soon as I close my ipad up and is locked or in sleep mode, I don't know anyone is messaging me until I look at my ipad.  I've tried a few things.. But nothing has worked so far....Please help!

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) http://support.apple.com/kb/ht1430
    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

    http://support.apple.com/kb/ts1630
    http://www.atreks.com/app-no-sound-on-ipad-4-%E2%80%93-what-to-do/
    To solve some sound problems, just follow these simple steps
    1. Go to Settings
    2. Tap on General
    3. Tap on Reset
    4. Tap on Reset All Settings
    What this effectively does is to reset some of your Settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It doesn’t affect your data. All of your email accounts will remain intact, as well as any SMS text or iMessages.

  • X230 shuts down when return from sleep mode

    Hi, 
    a week ago I am facing with a problem - I am entering the laptop in sleep mode, just closing the screen, and when I open the screen (expecting that the laptop should wake up) it starts usual OS boot from scratch, not hibernate.
    How to troubleshoot?
    win7 x64
     As I remember about 2 weeks ago I installed new VMWare player, latest power manager drivers.

    Hi Barabas,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that your Lenovo ThinkPad X230 is restarting while you try to wake it up from sleep.
    Go to control panel -> Power options -> Click on choose what closing the lid does (on the left side of the window) -> Select sleep -> OK.
    If the above settings are as recommended, update your BIOS and Intel Management Engine firmware to the latest versions from Lenovo Support page. Enter your MTM number in the “Quick Path” and download the drivers.
    Try reseating your memory. Try running the system with only one memory if you have multiple RAM in your system.
    Hope this helps!
    Best regards,
    Mithun.

  • Why is my Macbook Pro running so slow when returning from sleep mode?

    I got my new Macbook this past Christmas so it is about two months old. I have the 13" Macbook with the standard 4GB of RAM (not sure if that matters), but when I got my mac I downloaded a bunch of games and such which may have slowed it down initially, though I have downloaded OnyX and Appzapper to uninstall apps and clean my computer. Also I have deleted EVERYTHING from "Login Items" which I thought might help. Basically whenever I am done using my computer I just shut the screen, I don't shut it down or actually click "Sleep Mode" so I'm not sure if shutting the screen puts it in "Sleep Mode," but whenever I open my computer back up I get that spinning loading icon when I click on anything on my desktop and it usually takes 5-10 minutes of this super slow loading before I can actually use my computer. Not sure what the deal is but it is clearly super annoying and I'm hoping to find out how to get around this. I have six 2GB sticks of RAM that I am hoping to trade for two 4GB sticks of RAM to speed up my computer but I am not sure if that would even fix my problem. This is my first Macbook, besides my mothers Mac desktop that I have been using for years throughout High School, but I am a windows guy. I consider myself pretty good with computers, not an expert but I can fix 95% of the problems I encounter, but this one has been stumping me! Thanks a million in advance!

    Hello Linc -
    I hope you don't mind but I have a similar issue. Might I be able to enlist your assistance with this issue? I've done as you said, and I have copied the approximate range of messages during my most recent incident. What I'm noticing is that my Mac is staying busy even while asleep. I'm concerned about this behavior, hoping you might be able to help debug the situation and set me on a good path to resolution.
    Here's my data (I don't know for certain that I grabbed the proper amount or range of data, but hoping this will help):

  • Flicking noise when I boot my iMac from sleep mode??

    Another problem that has struck my iMac..
    Every time I boot my Mac form sleep mode it comes on and starts clicking/flicking like the fan's cough on somehting. I know it's not the fan and it's most likley to be the HD but worth asking just incase it's a problem that I can fix (which i dought).
    I think I'm going to take the Mac into a Apple store and see how much it will cost to fix. Because I can't see myself going back to Microsoft windows again if this brakes.. I would rather just wait and save for a new iMac.
    I've had this problem quite a while but never payed much attention to it as I thought it was because of the room tempreture. But it's annoying me now, so if anyone knows what it could be please tell me..
    Thnaks
    Nick

    Been waiting along time for this problem to be fixed. Unfortunately the update hasn't help at all and even made the situation worse. Now my airplay connection from iMac to stereo abruptly stops after about 10-15 min. so I have to go over and quit wifi, start it up and find my airport network. Not sure why it always has a problem with the apple airport network. My neighbor's pc network is always there.

  • Does the Alrt for iCal sound when my Mac Mini is in sleep mode?

    This is the first time I have visited this forum... I do hope you can answer this rather mundane question...not exactly high-tech, but the Geniuses at my local Genius Bar didn't know for sure....

    No.

  • HP DM3 - Mouse Freeze's up when the computer wakes up from sleep mode.

    Hi Guys,
    I just had a DM3 with the 2.26 sp9300 intel chip built for me and every time the laptop goes to sleep and wakes up the mouse freezes up with a magnifying glass and its impossible for the mouse to do anything.  I have to tab over to the task manager and tab down to the power button to restart my PC and than it works again. Anyone know whats going on?  Driver problem? any updates yet?
    Thanks !!
    Jon

    Hello,
    I picked up my DM3 from PCWorld last night and I'm having the same problem every time (4 times) when I've closed the lid and re-open it again.  The magnifying glass appears and I can't move the pointer using the trackapd and have to restart the machine to gain control again. 
    Any word from HP on a solution?
    thansk,

  • Satellite U400 wont turn on & when on wont come back from sleep mode

    I have a Satellite U400 and its a year and a few months old.
    In the last little bit it has been acting up, and it started with when the computer goes to sleep and goes to the black blank screen it will not come back from that.
    The only way to do anything is hold in the power key till it turns off and then turning it back on. This brings me to the warning screen I have turned my computer off incorrectly. It has been doings this for a few weeks and started randomly out of the blue.
    Then just today it wouldnt turn on at all, I was pressing the power key and the key itself would light up, and on the bottom right hand side the little lights would light up but wouldnt turn on, I kept pressing it over and over and over again and finally it did turn on. Once on I only used it for a few mins before turning off again and then would do the same thing, I kept pressing the bottom till it turned on. Its been on now and hasnt turned off again.
    Not to log ago I had to reformat my computer due to me forgeting my password and had locked myself out of the computer. About a week after that is when the issues started. I am not all that computer smart, to be honest, I do understand something things, I can follow step by step to do something.
    I really dont want to pay to have it fix I want to just do it myself and soon as its in great shape and never had any issues before.
    Does anyone have any idea what this could be, or why it could be?
    I am thinking about reformatting again as I am worried that didnt work out right the 1st time or something.
    Or if this is something that needs to be repaired does anyone have a clue on the cost of it?
    Thanks ^_^

    hi aev270,
    sounds like a serious problem to me.
    try the following: take out battery, cd-rom, hdd and try again.
    if it starts up without this components - you got lucky!
    this means it probably a software issue (but i dont think so - sorry)
    do you see the toshiba logo / bios messages? no - the you are in trouble.
    this strange behaviour could depend on many things: defektive components like ram or grafics... or (badest thing) the mainboard...
    if you have still warranty on it you should go to a servicepartner having the system checked.

  • Why does my computer turn black when I wake it up from Sleep Mode

    When I need to go somewhere or just eat lunch, I put my iMac to sleep. After that, when I come back to wake it back up, it stays black, I called Apple Support and they said I need to pay 20 dollars just to see if they can resolve the issue. So, if there is anyone that knows how to resolve this issue, I would very much appreciate it.

    Try resetting your iMac's SMC and see if that fixes your issue. This happened to me once with my MacBook Air and resetting the SMC did the trick.
    Shut down the computer.
    Unplug the computer's power cord.
    Wait fifteen seconds.
    Attach the computer's power cord.
    Wait five seconds, then press the power button to turn on the computer.
    Note: For Intel-based Xserve computers that are not responding, you can shut down locally, or by using remote commands, or by pressing and holding the power button for five seconds.

  • Magic mouse not working when my computer wakes up from sleep mode sometimes

    This does not happen all the time but it is starting to happen more and more. When my iMac is asleep and I wake it up the mouse is non responsive. I have looked at the green indicator light on the magic mouse and it does not respond as well. I have turned the mouse off then back on and that does nothing. I thank this may be a Bluetooth problem because I have tried this with 2 magic mice. The only way I can get it to work is to restart the computer.
    Please advise??

    I would add the mouse to bluetooth favorites in System Preferences > bluetooth > Highlight mouse on the left > click gear icon below this list > click "show more info" if not already checked > click the gear icon again and "add to favorites".

    If that doesn't do it then a SMC reset might be in order:

  • BT Keyboard Loses Connection When Waking from Sleep Mode

    I'm running Windows 7 on a late 2009 27" iMac and my Bluetooth keyboard keeps loses connection when I wake my computer from sleep mode. Usually the only way I can get it back is my resetting. Anyone know of a way to fix this? Any help would be great appreciated.

    If the MBP doesn't wake when you open the lid but does when you press any key afterward, do this:
    Applications > Utilities > Terminal
    Copy and paste the following text in the Terminal window:
    *sudo pmset lidwake 1*
    You'll be asked for your admin password. Type that in (Note: the password will not be displayed as you do so). Press Return, and quit the Terminal. Close the MBP, wait for it to sleep, and open it again. Does it wake now?
    If you want to change it back so the system doesn't wake when you open the lid, repeat the procedure, but this time type or paste:
    *sudo pmset lidwake 0*

  • Can't use mouse/keyboard/trackpad when waking iMac from sleep mode

    Basically as the title says. When I wake my iMac from sleep mode I am unable to use my keyboard/trackpad/mouse during the login window. Once the screen goes black by itself, after a minute or so I can then log in properly.
    Yes the keyboard/mouse/trackpad are all connected when it wakes from sleep as I can use any of them to wake it from sleep, I just can't move them or type with them in the login window.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain models. The next normal boot may also be somewhat slow.
    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. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Error in AJAX call when resume from Sleep mode?

    We have developed a HTML5 web app and added it to home screen the app is working fine. But the AJAX call is not working when we resume the app from SLEEP MODE. If the app keep opened.
    THIS ISSUE COMES ONLY IN iOS8.
    Please give the solution for the above issue.
    Thanks

    Sounds like maybe the eject mecinisim is stuck..? Try inserting a CD or DVD and then Eject it to see if that makes a difference.
    If not, try reseting both the SMC and PRAM
    as per > Resetting the System Management Controller
    and > Resetting your Mac's PRAM
    Then if it is still acting up, contact Apple or your local AASP
    at > Apple - Support - iMac - Service FAQ
