Macbook shutting down by itself, and very hot when being used

Hello!
My 2009 Macbook has me worried. When I put it in sleep mode and plug it in, it shuts down by itself at some point, so every time I go to use it again, I have to turn it on as though I had initially shut it down. Also, the bottom of my laptop is very hot.
Does anyone have any idea what might be going on? I am so grateful for your input!
I am just outside of my Apple Care warranty coverage, unfortunately.

Answer to ur 2nd question : it's quite normal ! don't be nervous.

My macbook shut down from itself

hi
after i upgrade to mountain lion my macbook pro shut down from itself when i'm searching or doing somethin (weird proplem)!
idk what's the proplem is it because i opened more than 2 apps (which i think it's a silly proplem if it's in the mountain lion)
or because i connected my iphone 5 wirelessly with my my macbook!
apple needs to fix this proplem, it happens everyday to me!
what do you suggest?

Hi,
Try a hard reset of your iPod: Press/hold the *home* and *sleep/wake* buttons until the Apple logo appears.
Hope this helps!

After 2 weeks my Iphone 4s shuts down by itself and I cannot turn it on. What can I do. Itunes is telling me to restore the phone but the phone is saying the software isn't available

My Iphone 4s shut down by itself after a phone call and I cannot turn it on. I took it to istore and they said it was unrespinsive and there is nothing they can do? Anyone has a clue what can be done? When I connect the phone to itunes it indicates that the phone should be restored, however when i try to restore it, it says the "software for this iphone is not currently available" Is there anything I can do other than put this brand new iphone in the grabage?

On computer, at the top of this page is a Tab for iTunes, click it, make sure iTunes is up to date. Also make sure computer Fire Wall and Anti Virus do not interfere with iTunes, turn them OFF to be certain.

Satellite A100 - Shut down by itself and will not boot anymore

Satellite A100 PSAA9A-10U038. Laptop shut down by itself whilst in use. No BIOS upgrades or changes. No lights of any kind showing, no POST.
I have tried the AC power adapter on another machine and works fine. Called Toshiba told me power adapter probably at fault, if I wish to have them look will cost $120.
I'm thinking maybe motherboard died? Any help would be appreciated.

hi Laptop Larry,
try to boot without the batterypack....
can you see the "toshiba screen" while booting?
you can also try to:
- remove hdd
- remove added memory (with no mem the unit should "beep")
- remove odd (cd-drive)
if you cant get the system to boot (able to enter bios, see toshiba logo on screen, no beep)
than it's possible that your mobo died...

Boatmoter, welcome to the forum.
Have you checked to see if the computer is overheating while gaming. Games are intense and can cause heat to rise. This can definitely cause the computer to restart unexpectedly. There are many FREE programs that you can use to check the temps.

Ever since my upgrade to IOS 5, my ipad 1 has been causing a lot of problems. The apps shut down by itself and I even have tried to reset the iPad but no real effect.

Help. Ever since my upgrade to ios5, any and all apps simply close by themself. I have tried to shut down all the apps which are not in use and I have also reset the iPad a few times (reboot) and yet there is no real effect. Is there a way to go back to the older ios so that I can have peace of mind. It is a crying shame to see all such hassles with ios5.

Downgrading to an older iOS version is not supported on iOS devices.
Make sure that you have downloaded all of the updates for your apps and see if that helps.
Try this as well. if the Apple apps are working OK and it is the third party App Store apps that are crashing - try downloading another app - any free app. See if that helps.
You said that you reset the iPad but you may have to restore your iPad to factory settings and then to a backup if you can't resolve the problem.

Monolingual, dead apps, shuts down by itself and reformat concerns

Hi, I'm new on Mac, so any advice given to me should be clear and without abbreviation, so I can follow it properly. Thx.
1- I used monolingual without unchecking all the stuff in the two last tabs. The first tab was for the languages, the two last, for the architecture and some other internal components.
2- Since then, my whole Office won't work. I also discovered recently that Toast Titanium and Mac the Ripper would not open either (I did not try them before, thought).
3- Lately, my MacBook would just shut down just after I open it, sometimes 2 times in a row before I can use it. It just happened 5 minutes ago, while I was just surfing on Firefox.
4- When Office was the only symptom, a friend told me to reinstall Office. Now that i have bigger problems, he tells me I should reformat Mac OS. He told me reformatting a Mac is a heavier operation, that as opposed to Windows, it keeps some traces from the older installation, that it is impossible to remove everything, just like if this installation waws the layer on which I a going to reformat and over which the new Mac OS is going to install itself.
I am aware I shoud reformat, even though I did not try to fix the shuts down any other way. I realized that it happens to a lot of user while reading the discussions of some topics. Anyway, my priority concern is the fourth point of my topic. I would still like to know if reformatting is my only way, if there is any other solution.
Thaks in advance, sorry for my bad English, I am francophone.
Regards

You have described two main problems:
1. You used Monolingual in a way that may have removed all the ability to run non-Intel applications, e.g. MS Office.
2. The shutdown problem.
To be sure of fixing the first problem, you can reinstall the OS. There are two choices for reinstalling: erase and install, or archive and install. They are described here:
http://docs.info.apple.com/article.html?artnum=301270
Once you have restored the OS, then you can see which applications do not work, and reinstall them. What your friend said about reinstalling the OS is not correct. If you do an archive and install, you will still have your old files from which you can choose what to keep. If you do an erase and install, none of your old files will remain on your disk.
If you are still having the problem with shutdown, contact Apple.

White Macbook (mid 2006) Runs loud and very hot, battery not charging

I know my Macbook is getting a bit old now, but I don't think the way it is running is very normal.
The battery will say that it is fully charged, but it will only last about half an hour when disconnected from the charger. The light on the charger will not come on either, or it will blink when i attach it, then stay out.
My Macbook will also run very loudly, and hot. I don't ever run too many programs at once, so I know that it's not a strain on the system from what I can tell.
I tried resetting the SMC since it sounded like the problems I am having would be solved by resetting it.
Are there any known problems such as these, or fixes? Thanks.

After Lion install Macbook shuts down by itself

At random times My Macbook just shuts down for no rhyme or reason. Then I have to wait for a few minutes before it will turn back on.

After upgrading to Lion, my computer overheated and I had to have my graphics card replaced. It's happening again, and I'm using a fan control program to keep my system cool. This is a bandage and I'll be asking Apple to look into this because there must be something wrong with Lion.
I have done the resets, both the SMC and PRAM/NVRAM. No effect, and that's true for the original video card and the new one.
I'm tempted to use the Firmware Restoration, but will wait on Apple support.
I have an iMac 24" from ~2006. It's worked like a charm until Lion.

IMac DV G3 Lime shuts down by itself and buzzes

Not sure why this keeps happening. It starts up and runs for about 20 minutes and then shuts down but the light on the front stays on and buzzes. Can't start up again until I unplug it from the wall for a long time. When it's running everything works fine. I LOVE this Mac and want to keep using it. I've had it since brand new oh 2000 something. I have an iBook G4 with 10.4 that I use for everything and everywhere but this iMac is the family computer. Can anyone offer advice? Should I take it to a Genius Bar? Thanks!

Hi,
I dumpster dive, gather, restore, upgrade and repair iMacs near Chicago.
These are typically high needs schools. Many have no computers at all!
The iMac is particularly well suited to this application.
A. It has a small foot print and is self contained.
B. Mac software is intuitive and easy for teachers and students to use
right away.
C. The kids think they're cute! I've seen kids hug iMacs! I don't see
that with any other computer.
So I can see why you're so attached to your Lime iMac. My 9 year old daughter calls her's "Pinky" (Strawberry iMac).
Generally the symptoms you're describing are due to a failing PAV board. This is the brown board that you can see under the clear top with all the big parts on it. The most likely culprit is the flyback transformer. The insulation breaks down with long usage when it heats up and starts to fail. Usually shorts out probably the buzzing you hear. Sometimes this will fail but the computer will still run with an external monitor. (spigot is under the perforated grill under toward the back.)
My general repair procedure with these is to pull the logic board and put it into a working 350.
An alternative in your case would be to find a working 400 - 700 used, buy it ($20 - $70 around here in Chicago) and swap the colored parts on your Lime onto that machine.

IPod Touch 5th Gen shut down by itself, and will not turn back on?

I was just on the YouTube app when suddenly my iPod shut itself down, and the battery was well over 50%.
It will not turn back on, and when I plug it into the charger, nothing changes. Any suggestions?

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.

The phone seems to shut down by itself, and won't start up w/out pressing power and home button

I shouldn't have to reset the phone to start it up. What is triggering this?
The phone will be shut off (pressed the power button on top). Normally, I just press the same button again, or the home button. Sometimes I have to reset the phone. It is a 4s with iOS 5.

Is there anything at all on the screen? Try this procedure:
Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

My iPhone 5 shut down by itself and can't be turned on.. help?

I woke up this morning and I couldn't turn on my iPhone. I've tried charging it, just in case if it runs out of battery, but still it can't be turned on. My lock button on top is slightly broken too...

Try a Reboot press & hold power button & menu button hold both down until you see Apple Logo You may need to do this more than once If your power button is broken Take iPhone to Apple Store they may exchange iPhone but you will need to pay part of cost. Bsydd uk

Iphone 4S shut down by itself and will not turn on.

I was using my phone in the car on Sunday and it was working perfectly fine, got home and placed it on the table. Went away for 10-15 mintues and I had come back to find it was off which I thought odd as the battery was almost fully charged. I attempted to wake it using the sleep wake button - nothing. I assumed it had gone flat for some reason so I put it on charge, an hour later still nothing, plugged it into the computer - nothing. Tried to hold down the sleep/wake + home button for 30-45 seconds - NOTHING Itunes wouldnt recognized it either it has been off since Sunday afternoon and hasn't turned back on at all - no heat either. It is still under warranty so I am hoping I'll get a replacement when I send it to apple it's about 10 months old + water indicators have not been set off.
Any help or ideas would be appreciated I think I have tried almost everything to try to get it working.
