Boiling hot while asleep?

I've been having trouble with my AppleTV overheating. The surface gets to over 110 degrees F while playing a movie, and at times the HDMI video will flash, flicker, or go black. While asleep the AppleTV is right now about 108 degrees, while the room is an ambient 68. Thats a 40 degrees difference!

Not to really defend Apple, but the case being a heat sink is why it is hot. If they went the traditional route, then it would 1, be bigger, 2, contain heat sinks (more parts) and 3, contain fans to blow the heat out (more parts and something else to power).
I think many relate heat to energy. Thinking, it is so hot, it must be using a lot of energy. Well it is more of the case of being tight and compact thus more focused heat not really using more energy. I would say the AppleTV is using less energy (and less parts thus less waste) than a similar product from somebody else.
As for standby mode...I know many have stated various outputs and since I don't know any of those that say they tested it, I cannot consider it reliable. However, the standby really is just sitting there waiting for iTunes to say it wants to sync. Really not doing much. If you really don't like wasting energy, why have your WiFi always on (that is all it is doing).
You are incorrect, heat generation is directly related to energy use. To produce heat you must use energy, the Apple TV radiates a significant amount of heat from its Heat Sink surfaces (case).
In standby mode the Apple TV is still running the power supply, HD, internal fan, WiFi, processor and TV Output (allthough it shows a black screen the output is still on).
The Apple TV internal power supply is rated at 48 Watts.
There is very little difference between the power used when on or in 'standby'.
If we are generous and assume that the Apple TV in standby only uses 30 watts (I suspect it is in fact higher).
If you use the calculator here :-
http://michaelbluejay.com/electricity/howmuch.html
And select a 30 watt device (like the Playstation 3), you can see that it costs $50 a year to run the Apple TV in the NY area.
In the UK I used the calculator here :-
http://www.ukpower.co.uk/running-costs-elec.asp
Using 30 watts for the Apple TV, makes a running cost of £28.63 ($42) a year.
This is a total waste of money and resources.
Yes I can turn of other devices and I do. It is a pity that other people don't, if we all did we would like in a far better world, that might have a future.

PB gets HOT while asleep

Hi all,
I'm sure this question has been asked before, so please forgive me ahead of time if this is a repeat. I've been doing some searching around the web on this, and I was able to find plenty of people asking questions about this, but never any solid answers.
The problem is with my powerbook when I close the lid to put it to sleep. Every once in a while, shortly after closing the lid, the sleep light stops flashing, then the fans come on (the bottom gets VERY hot), and when I open the lid I get nothing on the display and no response from the keyboard. I have to force a shutdown but holding the power button down to regain control.
I know that plugging in USB/FW devices while it's asleep will wake it up, but I have no devices connected (other than the power cord). Both my airport and bluetooth are turned off, and I don't use any PC cards.
Does anyone know what causes this and if there's a fix of any kind? So far the best work around I've found is to just shut the PB down instead of letting it go to sleep. The reason I'm asking is that over the past 5 years this has only happened a handful of times, but now I'm up to 3 times this week.
Thanks in advance for any responses!

Hi, ggarthe. You have quite an odd problem, and I'm not sure what could cause it. The Powerbook shouldn't be able, let alone willing, to wake from sleep with its display closed and no peripheral devices connected, and doing so is certainly not good for it.
Next time this happens, as soon as you're able to start the PB up again, open the Console application and look at the Console log, which is a chronological record of events in the computer's recent life. Near the end of the file you should find a "System Sleep" notation representing the last time you put the PB to sleep, and following that will be entries telling (in Consolese) what happened next. People who understand Console logs (not including me) may be able to discern a cause for what your Powerbook is doing from reading the log entries shortly before and after the Powerbook awoke with its display closed. If you'll post 40-50 lines of log entries centered on the System Sleep entry and the unwanted wakeup that followed, I'll try to round up some expert interpretive help for you here.

Really hot while asleep

I always carry my MacBook Pro in the sleep mode. Last night I got home and pulled it out of the case. The computer was really hot and the sleep mode light on the front of the computer was off. I opened it up and rebooted. The fans stayed on for a while, but the computer was fine. Some bump must have disturbed the sleep mode. This must be a very rare event, but it really scared me. Have other had this problem and perhaps lost computers?
MacBook Pro Mac OS X (10.4.9)

It is not a good idea to carry your machine in sleep mode. That doesn't protect the hard drive or screen as well as being shut down, and there is the potential if the latch comes undone, for it to wake up in the bag, and overheat. Shut down notebooks in travel.

My phone switched of while charging was boiling hot aswell and wont turn back on or connect to laptop, help ..

My iphone 3gs switched of while i had it on charge i didn realise untill i went too use my phone and it was boiling hot when i picked it up, it will not switch back on, charge or connect to laptop or dcu mode .. any ideas on what to do with it other then back to belfast .. all tips welcome ...

Unplug it, let it cool down and try to reset it by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

MBPro (brand new) Hot While Sleeping!

Brand new 15" MBPro. I've notice the machine seems very hot while sleeping (and power adapter plugged in).
Today I tried leaving it unplugged while asleep (full battery) and the battery ran out of power as if it was awake and running an application?
Any ideas? Like I said, its brand new and I haven't even finished loading all the software.
I gotta say that I like my old G4 Titanium better. I love being able to open the monitor greater than 90degrees!
Thanks!

I think I figured out my non-problem. Last night I did a hard sleep rather than letting it "fall asleep". It was nice and cool this morning.

Iphone getting hot while sleeping.

i put my iphone to sleep and left it for a few hours. when i went to use it it was extremely hot but it was asleep the whole time. wifi is off on the phone. has anybody experienced this at all.

I noted the iPhone got extremely hot while charging attached to my Mac this afternoon, yet when I switched to wall outlet charging it immediately got cooler. Yet the phone was not even in use during this period. I tried to isolate the problem by removing it from the Speck ToughSkin, thinking perhaps the rubber cover was the cause. But it got quite hot again later while using WiFi and then suddenly taking a call and receiving two text messages. Yet five minutes later, it was no longer hot. Very peculiar. Other user experiences like this out there?

My iPhone 5 gets very hot while in use or just charging?

Is it normal for the phone to get so hot while being used just for simple things like listening to music or charging

Hi Lizard914,
It is entirely possible that what you're experiencing is within normal limits. Here is an article with additional information:
iOS devices: Keeping device within acceptable operating temperatures
http://support.apple.com/kb/ht2101
When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside.
Take care,

Is it normal for my charger adapter to get hot while charging.

IIs it normal for my charger to get hot while charging. Very hot

Hot/ Very Hot are very relative.
Its normal for it to get hot while charging, but if its really unconfortably hot to touch even briefly then there might be an issue.

Fans come on while asleep

I am using a 21.5 iMac (bought in Nov 2009 I believe).
While asleep, the computer fans will come on after variable time intervals. I hit the power button and the fan goes off only to come back on. The fans run only at medium levels.
I do have wake on lan turned on but I have disconnected the Ethernet cable and turned airport off. When I wake the computer with the fans going, Activity Monitor shows no process going except Activity Monitor. The only peripheral attached is an empty usb-ipod cable.
Any thoughts?

Is it ok for my iPod 4g get hot while playing a game

Is it ok if my iPod touch 4g get really hot while plaing games?

It is normal for the iPod to get worm during heavy use like gaming. If you are concerned, you can always make an appointment at the Genius Bar of an Apple store.

MacBook Pro Runs VERY HOT while sleeping after Mavericks update.

My MacBook Pro (2009 model) runs super hot while it's sleeping after upgrading to Mavericks. Additionally the fans run at a very high speed. This issue was not present before the upgrade.
I'm concerned that there is a bug that's going to shorten the life of my machine as it will lieterally run all night like this.
Has anyone else experienced this, and is there a solution?

Others have reported an issue with their systems after upgrading to Mavericks that might be related in https://discussions.apple.com/thread/5497235
No fix is posted yet, but you might want to check to see if you have the kernel_task process using 100% CPU after coming out of sleep, and if plugging/unplugging headphones stops that task from using so much CPU.
It shouldn't be the new Power Nap feature in Mavericks, as your system appears to be too old to support it, but you should check your settings to see if it's enabled: http://support.apple.com/kb/HT5394

HT201263 My I phone 5 got hot actually very hot.. Boiling hot and then the battery charge went from 100 to 50 and within a minute was shut down and never on again...I bought the phone from the apple store in manhattan new York I bout the unlocked phone

My I phone 5 got very hot actually boiling hot although it was not exposed to any external heat ...it was fully charged and within 10 minutes it was half charged 50% and within one minute it was shut down ... Tried re charging through the computer and through the power but no response the phone is totally black... Tried connecting to I tunes and no response.. The thing is that I bought the I phone 5 on the 23 rd December 2012 from Manhattan new York and I live in Qatar and there is no service centre in qatar .. I am now without a phone although I paid 706$ and that's a big amount .. I am disappointed .. I bought an original phone from the original apple store and I ended up with a product that didn't survive for a month.. What quality assurance do the apple have on their products...I need help here

I appreciate the fast reply.
Well, I checked the iphone and the battery charged going from the bolt to the plug in the upper right hand corner very quickly. On my other cell phones, charging took a REAL long time.
Again, is this normal? I unplugged the iphone from the charger and I am going to monitor the battery power today. I find it odd that the battery would work on standby for 4 days without recharging the battery and then start doing something wacky. Any thoughts?

Does my iMac check for new Mail messages while asleep?

The Energy Saver settings on my iMac are to sleep the display after 15 mins. and the computer after 20 mins. and I do check "Put the hard disk(s) to sleep whenever possible."
Two questions:
1. *Is permitting my hard disks to sleep helpful or harmful to my iMac in the long run?* I care less about energy costs than the long-term health of my computer. So what's worse: spinning the hard disks down (causing wear and tear) or constantly exerting the disks by never letting them rest?
2. This is the key question for me at this moment: *while asleep, does my iMac retrieve new email messages?* This is an issue because I have a number of Rules I've setup within Mail on my iMac that move messages to certain folders. So if the iMac is asleep while I'm out and about, these messages clog up the inbox on my iPhone's Mail app until I come home and wake the computer (I have a gmail IMAP account). Also, does checking the option to put the hard disk to sleep affect my iMac's behavior in retrieving email while the machine is asleep?
I'd appreciate any clarification.
Grant

1) There are lots of arguments about all kinds of esoteric questions and whether you should spin down the drive or not sounds like a good candidate. Drives do die of course, but in the greater scheme of things you and I are more likely to either replace the drive for something larger or replace the computer before that drive dies.
2) If your computer is asleep it cannot check for mail or do anything else for that matter. End of story. Assuming you have broadband, when you restart/wake your computer it may appear that mail has been accessed while the computer was asleep but that's because your mail application probably checks as soon as the computer was awakened/restarted.

Pismo shuts down while asleep. PMU cause -96?

Hi. My Pismo has recently started to shutdown unexpectedly while asleep. Since it's intermittent, I can't really tell if it realy goes to sleep and then shuts down or if it just dies when I close the lid, but not only MacOSX took notice of a forced shutdown (and offered to report it to Apple, but the CrashReporter never came up), it also had a line in system.log with "localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -96".
Now, I know that ApplePMU messages seem to be some kind of state secret at Apple and that several guys with G5s are having problems with cause -122, but does anyone have any experience with this?
I've only been noticing it lately because I have a new battery and now I keep it sleeping far longer than before, because my old battery only had 5 minutes of life in it and this Pismo was basically chained to a wall.
Powerbook G3 Firewire Mac OS X (10.4.5) 1GB RAM, 40GB HD, Airport

Tiago,
I don't know what the error -96 represents, but I have seen the same PMU Forced Shutdown with numbers like -122 and -127 (again, no info).
I would reset the power manager and PRAM, then test.
You mentioned not knowing if it crashes or shuts down immediately; if you see the pulsing sleep light, it still is sleeping normally.
Does this issue occur only on battery or also when connected to the power adapter?
