Anyone notice their MBP really hot when taking it out of a bag?

Hey everyone,
I have had my Macbook Pro for about 8 months now and just today I took it out of my laptop bag and found it to be very HOT. It's like it came out of it's own sleep and ran inside my bag. Since there was no airflow it got very hot. How do I know if this caused damage to my laptop? I am very concerned about it. Any information would be helpful.
Thanks,
-David

Hi David,
Waking from sleep unintentionally is something that can happen, but shouldn't happen. Often, Bluetooth settings can be set (possibly as default) to allow the machine to be woken from sleep by a Bluetooth device. If you go to your System Preferences, and click the Keyboard and Mouse pane, and then click "Bluetooth" then you can uncheck the box that says "Allow Bluetooth devices to wake this computer". This should stop this from occurring in the future.
If you do use Bluetooth devices, then you will have to either wake the computer manually (by opening it) or be more careful with the computer when it is sleeping in a case. Even passing Bluetooth devices in other people's bags can possibly wake up the computer when that checkbox is checked.
I wouldn't worry about the heat that the computer was exposed to this one time. The machine itself is designed to shut itself off at temperatures that are dangerous to it. Therefore, you should never have any heat-related damage.
In terms of sleeping the machine when carrying it in a bag: Continue doing it, but with this checkbox unselected. There is nothing wrong with carrying the machine while it is asleep! I do it all the time and have never had any problems!

  • My MacBook Pro gets really hot when I open a video file of any kind and the video starts lagging and the image fades away, also with anything that starts the fan. Is extremely hot on the left upper corner. Is there something I can do about it?

  • Why does the IPhone 4 get really hot, when you are making a phone call??

    I can't seem to find the answer to this riddle . why does the iPhone 4 get really hot when you are making phone calls or when using face Time ??

    It doesn't.
    There must be an issue with your iphone.
    Have you tried reset?  Restore?
    Have you made an appointment at the genius bar to have them look at it?

    my ipod touch won't hold a charge and gets really hot when im using it. what is going on?

    Likely that the battery is dead.  I would make an appointment at the Genius Bar of an Apple store to confirm. Apple will replace the battery for this price:
    Apple - Support - iPod - Repair pricing
    There are third-party places which may be less expensive.  Here is one. Google for more.

  • What should i do if my ipod is getting really hot when i use it/

    I need help my ipod keeps getting really hot when i use it

    I would suggest you stop use for a period of time until it cools down. When you turn it off, make sure you exit out of whatever program you are running. If it persists getting hotter, to the point where it's hard to hold, I would suggest you take it into the Apple store nearest you. Depending on how long you have had it, they may be able to replace it for you free of charge.
    It is abnormal for that device to get extremely hot but when it is running multiple programs, such as playing music and surfing safari, it can heat up.

  • My MBP really hot and really slow recently

    Hi,
    My MBP has become really hot and noticably slower recently (within the last 4-5 months). Before I could keep it on my lap for hours watching video using VLC and run a bunch of other applications (like Safari, Firefox, iTERM, Nisus Writer Pro, TextMate, etc.) without it getting unbearable.
    Now, even when it's nearly idle (running just Safari, with Quicksilver in the background) the temperature is around 130 deg. Fahrenheit, give or take 10 degrees. And the usually silent fans continuously give out an evil hiss.
    The only changes I made to the MBP within that time are:
    1. Upgraded to 10.5.6
    2. Added growl (which I turned off for now)
    3. Purchased some software via MacHeist, which includes:
    acorn,
    appshelf
    boinxTV
    CroMag Ralley
    Espresso
    iSale
    Kinemac
    littlesnapper
    picturesque
    SousChef
    Hitlist
    Times
    Wire Tap Studio
    World of Goo, and
    eventbox
    4. Upgraded to Safari 4 beta
    And that's about it. Safari seems very sluggish on the initial launch, giving me the spinning ball, and more often than not, it would freeze and I would have to force quit. But then again, the previous version crashed quite often too, but I seem to remember it to be pretty perky on launch.
    The only things I run in the background and/or login items are:
    1. Font Agent's font activator
    2. Quicksilver
    3. iTunes Helper
    4. Stuffit's MagicMenu
    5. MenuCalendarClock iCal version
    6. Expandrive
    7. Little Snitch
    8. MacFuse
    Also my wireless connection to the USB drive on my AEBS seem to have slowed a lot too. At one point, I was reading and writing to it at almost the same speed as if it were plugged directly into my MBP's USB port. Now, it's around regular ethernet speed (not fast ethernet, nor gigabit, just regular 11Mbps).
    Anyone have any idea? I'm thinking of just reinstalling from the 10.5.2 DVD I have, but that means I have to backup everything and I know I'll lose something during the process, because I have a WD 320GB disk and have used it all up except for about 10GB. It's gonna take a good part of a day (or two) to do the complete reinstall.
    Any help as to why my MBP's so sluggish and hot would be GREATLY appreciated. Thanks in advance.

    Yes, you need more free space on your HDD, for sure. But...
    Let's back up a minute. I just re-read your original post - 130 °F is NOT hot. That's barely warm. Most of us are used to looking at temps in Celsius (at least, I am). 130 °F = ~55 °C. My CPU is at 49 °C right now, 5 minutes after waking the machine up from an overnight sleep in a cool downstairs office. Normal MBP idling temps are in the mid 50s °C (the 130s °F), so you are most definitely not having a temperature issue. Running a heavy CPU load will push the temps into the 70-80 °C range (160-175 °F); fans normally don't spin up past idle speed until the CPU/GPU temps are in the 70s °C (your idle speed is 2000 rpm).
    So, if the fans are making an 'evil hiss' that's not due to temperature.
    To conclude - your initial issues were 1) really hot, 2) noticeably slower and 3) an evil hiss from the fans. So, #1 is a non-issue, since your temps are quite normal. #2 is most likely due to lack of HDD free space (you've run out of room for virtual memory and swap files). That leaves #3 - just how evil is that hiss? What fan speeds does your monitoring software (iStat Pro, for example) report?
    Have you run the Apple Hardware Test? (Insert Install DVD 1 and reboot with the d key pressed.) That will check out your fans, sensors, etc.

  • My macbook pro is getting really hot when I leave it running but put the screen down.   When I open it only shows password box not rest of screensaver.  I'm not doing anything differently

    The past 2 days my MacBook pro has been running really hot, especially when I close it.  When I open it the screensaver doesn't show completely.  Yesterday when I moved the mouse it made spiral trails with the graphics, very strange.  I'm really concerned!  Help... I've restarted it, powered it off last night, etc.

    You can always take your Mac in and give it a check-up for free. What will cost you is the repairs you select to have preformed. I recommend shutting your Mac down before you go to bed. Problem solved. There is no need for you to keep it running if all applications are quit. Why do you need it on?

  • Anyone got their MBP back?

    Anyone sent in their MBP for CAPTURE? Have you got a new one back yet? Does it still whine?

    Hi,
    Could you please tell me how many video`s you encoded using Handbrake, 3hrs seems a long time if it was only one
    I used to do a 4.5 gb video in around 30 mins on my Dual G5 2.7.
    Have ordered a MacBook Pro but if it`s that slow using HandBrake then I will cancel my order.
    Also are you using the Latest HandBrake which is now Universal Binary.
    Have Been waiting since the 12th Jan for My MacBook
    Hope it`s been worth it, I`m expectng good things from this Baby!!

  • My iPhone 6 has started getting really hot when I am on the phone.  Any thoughts?

    My iPhone 6 has started getting hot when I make calls.  It does not do this when I am using my apps.  Thoughts?

        Oh no! I know that the iPhone 6 is one of the hottest smartphones but I didn't mean literally! Let's cool things off with your phone. Have you adjust your setting to extend battery life? If not, here's a link to check out, http://apple.co/1xnEkjF. Also, do you close out the apps that are running in the background to ensure proper resource management? Here's a link on how to do so as well. https://support.apple.com/en-us/HT5137. Once you have done so, please retest & keep us posted.
    Thank you…

  • MBP running hot when connected to Cinema Display

    I have a 2.33 MBP that I use for work and at home. I also have a 23 inch Cinema display on my desk at home. I have noticed that when I have my MBP connect to the Cinema and the screen on the MBP closed it runs hot and the fans never seem to stop running. I was wondering if anyone has seen the same thing and if so what they have done to resolve the issues. I have had looked at the laptop coolers that go under the laptop and that powers the fans off an USB port, but I really like my desk clean and don't want to add something else to it. Any ideas or suggestions would be great.
    Thanks
    Matt

    Try running with the lid open and see it temps drop.

  • Has anyone had their MBP die after installing a new hard drive?

    hi,
    the reason why I ask is because:
    a while ago I had a lovely PB12" which was my favourite little laptop.. the only thing it was missing was hard drive space, so I had a certified apple centre install a 250GB drive in it to make it a much more usable personal machine. a few days later the motherboard fried itself, and because the machine was long out of warranty, there was pretty much nothing to be done about it. I'm pretty sure it was a dodgy job on replacing the drive that killed my machine but I obviously can't prove it.
    anyway that was then, this is now.. I'm thinking about replacing the 100GB 7200rpm drive that came with my MBP core2duo 2.33 17" machine, seeing as there are now 7200rpm drives as big as 320GB. but I really rely on this machine for a lot of work, and I'm not exactly ready to have it mysteriously die just like my old powerbook. I know the 12" powerbook was apparently notoriously difficult to open up and replace components so I get the feeling that the technicians must have bashed something up when they were trying to do the swap out. so my question is, has anyone at all with any recent MBP had the machine go seriously wrong after changing the drive? looking around on the internet it seems that changing the drive in my current machine is something easy enough that I could do it myself, which I'd probably do if I don't hear too many horror stories about it. my MBP is out of warranty and I don't have apple care, but is it correct that even if it still was under warranty, that would have been voided by my changing the hard drive?
    anyway, any experiences and opinions on this most appreciated, especially from anyone who has had major problems..
    cheers,
    antonio

    thanks for the replies, appreciate the feedback.
    as I mentioned in my original post, I think I'm probably overly paranoid because of the fact that an authorised repair centre managed to kill my PB just doing a simple drive switchover. but from everything I've heard, the powerbook 12" was already in a category of its own in terms of how difficult it was to access parts inside, with a high risk of breaking something in the process. so I'll probably end up swapping out the drive on the MBP myself, perhaps with the help of someone more technically nerdy than me (and who has the right tools).
    I originally got a 7200rpm drive, and will most probably go for the latest 320GB 7200s that are out there because I need the best performance running logic. but I'm also slightly tempted to go for a 500GB 5400 because I've heard there's not much in it performance-wise nowadays given that the 5400s use perpendicular technology rather than longitudinal. do any of you know if the current 320GB 7200s also use perpendicular recording?
    thanks!

  • IPhone 5 getting really really hot when plugged into MacBook Pro Retina?

    Hi
    I have had my Macbook for about 1 month and I recently discovered that my phone is getting extremely hot while charging through USB port.
    I was not sure if it was my phone as I was having issues with volume buttons, so was not sure if I had some dodgy software or something. So I went to the apple store and it was replaced as it was actually a hardware issue.
    But then with my new replacement iphone 5 I am still having the same issue of the phone becoming unbearable to touch because it is so hot!
    Does anyone know if there is an issue with the Macbook Pro Retina's giving out too much power and whether I should go and see someone about the issue ? But in the mean time is it still okay for my phone to be charge this way?
    Thanks
    Elle

    You said:
    "So far so good on the iPhone but it does not appear to be charging when I have it plugged into my MacBook Pro."
    My iPhone charges when connected to my MacBook.
    "FYI...the Edge Network out here in Wichita (of all freaking places) Kansas is pretty darn fast. I was really, pleasantly surprised. It does not help my heartbreak over moving to this burg from Sausalito but it helps a little."
    Even data is anxious to leave Wichita, it seems .. and wants to linger in Sausalito

  • IPod Touch 3rd generation is not turning on and gets really hot when I plug it in but is not charging...

    I have an iPod Touch 3rd generation and yesterday I was using it and noticed that it reset to a different time zone and when I dug a little deeper realized that it reset the date to December of 1969. I just went in and changed it all back. I was out of the house all day today and didn't take it with me, when I went to use it, it wouldn't turn on. I assumed it was dead, so I plugged it in and got ready for bed. I realized that the charging screen never appeared and it never made the little noise it does when you plug it in. I picked it up and right near where the charger plugs in, it was very hot. I use it when it'd plugged in from time to time and it is NEVER that hot. I then tried to plug it into the computer where it again didn't do anything and didn't show up as a device that was plugged in on my iTunes. Again, it got very hot very quickly. I am using the cord that came with it and an actual Apple brand wall charger. I don't know what else to do. Some people said to hold the two buttons down for a little bit, but nothing happened on mine. Please help!

    Warm is normal, too hot to handle, literally, is not.
    If you're concerned, make an appointment at your local apple store and have them check your charger out.

  • IPhone 5 randomly shutting off and gets really really hot when it's charging

    I have had my iPhone 5 for a month now and it started randomly shutting off and it would turn on by itself hours later. When I charge it, it gets incredibly hot... it's not normal should I go to the apple store about this issue? I am starting to get really scared about this... I don't know what it's causing it. How do I fix this? HELP!

    Your phone is still under warranty, due to the battery service. Contact Apple and have them check the phone again.
