Mail just shuts off when sending

About 1 in 10 times that I try to send an e-mail, the e-mail application just shuts down, it goes away! What is the deal. I might spend 10 minutes typing an e-mail and then when I push send, the phone returns to the home screen.
Man this is irritating. Anyone else have this problem? Any solutions?

Both edge and WiFi
However, I do not think you guys understand...this is a software issue. The network you are on should not effect the functionality of the software in this issue.
1 time out of 10, when I push "send" the iphone exit's mail and returns to the home screen. It does not even attempt to send the mail. This transition is immediate and very quick. Some of you have experienced it when you are browsing the internet using safari and the browser just shuts down. The mail problem is very similar.
Is anyone else having this same problem.

My iBook just shuts off when it is still partially charged. Help?

Hello, I have an 14" iBook G4, and have been having problems lately with the computer shutting off (going dead, and not into sleep mode) after it has been running on battery power for awhile. It usually shuts off when the battery is at around 45-60 percent charge still left. It never shuts off when plugged in to the charger. Here are some specifics on the battery from the System Profiler:
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1545
Remaining Capacity (mAh): 1542
Amperage (mA): 0
Voltage (mV): 16543
Cycle Count: 225
I have been thinking about getting a new battery but I just replaced this one a year or two ago so I don't think it should be bad yet.
A few things that I think might be causing the problem might be that I upgraded this computer a while ago by putting in a 100 GB hard drive and putting in a Superdrive (it originally had a 40 GB HD and a Combo Drive). I also have an extra 512 MB of RAM installed. I also just recently upgraded to Mac OS 10.4.11. I had been running 10.4.6 for the longest time (mostly because I always though it was safer because sometimes when I had updated computers in the past they'd run into problems. Plus, I have software that I knew would run with OS 10.4.6 - plus the install discs).
Anyway, let me know what you guys think I should or could do to fix this problem. I'm on my computer all the time so I should respond quickly to your guys' (or girls') advice.
Thanks for any help you can give. Later

I looked into resetting the PMU (although I think I already tried that a week ago), I don't know if something specific is supposed to happen to let me know something was reset but everything functioned pretty much as normal.
I tried recalibrating the battery with minimal success, it went down to 31% then actually said 0% and died. I tried recalibrating twice and it doesn't go into sleep mode, it just dies. It'll go down to 0% and still not go into sleep mode. Now my battery reading says this(with the power cord unplugged):
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1315
Remaining Capacity (mAh): 1313
Amperage (mA): -778
Voltage (mV): 16178
Cycle Count: 225
I took continual readings of the Battery in the System Profiler and pasted them into a Word document when the computer was at 0% capacity and was still on but wouldn't go into sleep mode (it eventually just died). I can post some of those on here if you want.
I also tried that Coconut Battery program to let me know any new information about the Battery and it says nothing really new. It says the battery has a max capacity of 1315 mAh (although just couple of days ago it used to have around 1500mAh - read my first post above - I don't know if that means I've made progress or the battery is worse off then when I started) and also the Battery originally had 4400 mAh capacity (so now it's at about 29% of its original strength).
One thing did disturb me though is that the battery might not be recording the number of cycles correctly. Even though I've gone through at least a few charges in the last couple of days, it still says "225" and it should be higher. You'll even notice that it said "224" in the Battery Information in my first post. I've gone through at least a couple of complete discharges, I would think.
Anyway, I hope there are some more options on the table, but I'll see if I can keep re-calibrating it and it will finally work. I am starting to wonder if its the battery or the module inside it or some other problem. Anyway, thanks for the help.

My 6th gen nano just shut off when i was working out. anyone else have this problem?

My ipod touch just shut off when i was listening to some music. Now it wont turn back on, do you know why? Please thanks...

IS THERE A REASON WHY MY IPOD TOUCH WONT TURN BACK ON.? BEFORE IT SHUT OFF MY BATTERY WAS FULLY CHARGED. ANY SUGGESTIONS OUT THERE TO HELP TURN MY IPOD BACK ON PLEASE...??

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My iPhone 3Gs randomly shutting off at any given moment. I could be in the middle of a text, a call, or doing some games and it'll just shut off.
Now here's the unique part. When I go to turn it back on, the apple loading screen pops up but it takes somewhere from 3-5 minutes for it to boot up. Then the lock screen with the time and whatnot shows up. From this point on, my iPhone has a chance to shut itself back down and I have to repeat the process over and over again. Most of the time the lock screen flashes and then goes straight to black (shut down) but sometimes I can make it a few menus before it shuts itself down.
The only way to keep the iPhone on is to plug it into a charger of any sort. I'm fairly certain it isn't a battery charge issue because this happens at any % of power and sometimes my iPhone can use up all of its charge and not have this happen while other times I can be at 90-100% and it could randomly shut itself down. What can I do in this situation if some has some solution to this problem please let me know on [email protected] Thanks!

Not sure if this Term is Relevant towards an iPhone but, my iPhone won't Post unless if it's plugged into a Charger.

When I try starting my iPod touch, it won't start; the Apple logo comes up for a few seconds, and then, it just shuts off. I tried to charge it through an outlet; the iPod didn't even charge, so I tried to restore my settings on my computer. iTunes won't

when i try starting my IPod it won't start, the Apple logo comes up for a few seconds,and then. it just shut off . I tried to charged it through an outlet, the IPod didn't eve charger so I tried to restore my setting in my computer, i tunes won't

But that requires the computer to see the ipod. I am having the same problem and I keep being told to restore it, but you have to either get the ipod to turn on or have the computer see it in order to so that. Right now I have a pretty useless 32GB ipod touch cos I cant get the thing to turn on! I can only get the apple logo for like maybe 20 seconds and it goes away. Ive charged it for days on a wall charger, on the computer usb charger, and on a speaker charger. Nothing works.

14" iBook G4 shuts off when I open it up

I just started having this problem two days ago with my iBook. When I close it everything looks fine, the little light in the front is lit showing that it is still on but when I open up the computer, instead of waking up, it just shuts off and then won't turn on forever. It seems like I have to hit the power button just right for it to come back on. It does not shut off at any other time, only when I open up the computer. Other than this I have no problems. It does not appear to be the battery and it does not shut down at any other time. Why is it shutting off when I try to open it and why will it not turn on again? I hope this question makes sense!

nerone,
but when I open up the computer, instead of waking up, it just shuts off and then won't turn on forever. It seems like I have to hit the power button just right for it to come back on. It does not shut off at any other time, only when I open up the computer. Why is it shutting off when I try to open it and why will it not turn on again? I hope this question makes sense!
I tried to put it to sleep through the Apple menu and it also shuts down then.
OK that last step eliminated the cable, reed/cable and inverter problems.
So that makes it a PMU problem. The PMU is actually a tiny computer within the computer. It's official designation is PMU99.
http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G4/12inchPowerBookG4/2_Architecture/chapter_3_section4.html
"Power Control IC
The power manager IC in the 12-inch PowerBook G4 is a Mitsubishi M16C/62F microprocessor, also called the PMU99. It operates with its own RAM and ROM. The functions of the PMU99 include:
*controlling the sleep and power on and off sequences
*real time clock
*controlling power to the other ICs
*monitoring the battery charge level
*controlling battery charging
*supporting the interface to the built-in keyboard
The 12-inch PowerBook G4 can operate from a 15-volt power outlet on an airliner, however for safety reasons the computer will not allow battery charging. In order for the computer to detect the connection to airline power, the airline power cable should have a sense resistor of 24.3K ohms connected between the power plug's shell and ground.
The PMU99 also provides the hardware interface to the keyboard. Software in the PMU99 IC scans the keyboard, then sends the data to the system in packets like those from the ADB. To the system, the keyboard behaves as if they were ADB devices"
Try resetting it:
http://docs.info.apple.com/article.html?artnum=14449
If that doesn't work try what I call a deep PMU reset.
Pull all power including the battery, push the power button to remove residual charge in soft start capacitors.
Then walk away from it for at least 10 hours.
Try it again in the morning. Stuff like this has happened and people have left things alone and come back days, weeks and months later and their Macs are fine.

Please Help! MBP shutting off when plugged in, now not recognizing MagSafe Adapter

I started seeing this problem a few weeks ago, my MacBook Pro just shut off spontaneously while watching a video full-screen. I turned it back on and the problem went away for a while. But now, the shut-downs happen more frequently. It doesn't matter if the MBP is running off of the battery or if its running off of the AC cord, it will just shut off. No warning. No standard shut-down process, everything just stops and a balck screen shows up. After it shuts off, it takes a few seconds to get it to restart, and when it does, the computer's date and time will be reset to some date in 2000. Very strange, I've had this computer for a year and I know people with the same model that have had no such problems. The battery is at 168 cylces (I use this for school, so it was being used everyday throughout the last two semesters), and the Condition is listed as Normal in the System profiler, so I doubt the problem is with the battery, but I could be wrong. I've seen posts about the RAM/PRAM causing the date/time resets. Nevertheless, the MBP has been running normally on the battery, battery life is still the same length of time as it was when I first got the computer, and runs smoothly. Up until last night, the AC MagSafe Adapter was still working, so I only used that as the power source. Everything was fine, but the MBP shut off once or twice while it was plugged in within the last month or so, but the AC would still have a green light, indicating the computer was still recognizing the power source. Now, I can't get the MagSafe to be rocognized at all. The computer is running on battery only, and I've tried resetting the SMC, but I'm unsure if it worked since the MagSafe is still unrecognized. When its plugged in, the System Profiler says it is not connected and not charging.
I'm running on Mac OS X 10.6.8, a 2.4 GHz Intel Core 2 Duo, with a 4GB memory (of which less that half is used). Computer usage is low, so its not like I'm running several programs at once, at most, its two or three at a time, for short periods. My MBP is a 13" aluminum body, doesn't seem to be overheating, has worked fine after long periods of being on and getting hot, I always let it cool down after I feel it getting too warm.
Please help if you can! Thank you!

HT1338 My Macbook Pro is just shutting off by itself

I just upgraded to Mountain Lion but it was happening before that tool.

Hi Leslie198,
If you've just updated to OS X 10.8.2 does the MacBook Pro still shut off when you have it connected with the magsafe power adapter connected to the mains?
If you can get in to your mac, open About This Mac from the Apple Menu and select More Info, this should open some details up about your MacBook Pro, click on System Report and tell us what model you have it's next to Model Identifier.
Select Power from the options on the left and Copy & Paste the contents of this screen into a reply to this post, we should be able to see the health of your battery from this.

MBP Shuts off when there is slight movement

Hi,
Today my MBP started acting weird. I've never had this problem before. If I tap it, or move the lid it randomly shuts off. I'm afraid to type to hard b/c I feel like it will just shut off with any slight movement. I've reset the SMC and done a bunch of other troubleshooting.
Is this a software issue or hardware?
I feel as if there is a sensor loose inside my mbp which is causing it to suddenly shut off.

Bound to be hardware, Rudy.
Does it occur both when running from battery and from the mains?
Is it definitely shutting right down rather than falling into an unwakeable 'sleep"? (If it is shutting right down then a single press of the power button is all that is needed to restart, rather than holding the button down for a few secs and then pressing it again.)
What model is it?
Cheers
Rod

Help! My iPad just shut off wont charge or come back on? Whhaaaaa

Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - 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.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
