HT201177 when I power up only the fan turns on then shuts down

0can anyone tell me whats going on

Try resetting the SMC. Be sure to follow the right procedure. For a unibody or Retina, use the "for a battery you should not remove yourself" method.

HT3964 I just upgraded to Snow Leopard then Lion and the computer shut down after installation. Now when it starts up it gets as far as the apple icon and then shuts down again

I just upgraded to Snow Leopard then Lion and the computer shut down after installation.
Now when it starts up it gets as far as the apple icon and then shuts down again
whenever I turn it on it loads that far and then closes.
HELP!

Restore your bootable backup/clone or Time Machine backup of Snow Leopard, launch Disk Utility from the install disc, repair the boot volume, and reinstall Lion.

IPad starts (only the logo shows up) but shuts down after approximately 10 secs.

My iPad turns on, the apple shows up and shuts down immediatly afterwards. It does the same thing on and on until the battery runs out. I've tried everything written on the net and on your site (recovory mode etc..). Help anyone? Thank you !

Help!
My powerbook starts fine boots the system. gets as
far as when the system shows the right hand dropdown
menus then blacks out. some times the screen flickers
first. It then will not start again unless I reset
the PMU. then It starts fine only to repeat the
problem.
I have tried it with another adapter, and its the
same.
I've tried several PMU resets, and pram reset.
unplugged it for several hours with he battery out
programmmers button etc. But the problem persists.
Any suggestions at all are welcome
further to my first description, the powerbook will run start up of the battery the go to permanent sleep after a few minutes.
also and wierdly, its will run ok with the power plugged in for as long as the battery charge lasts. Then it does something similar to sleep. but without thesleep light.
I'm am really scratching my head here.
Any feedback would be gratefully recieved

The device was drawing too much power and that the USB port will be shut down

New to forum, help,
Cannot add a USB hub, powered or not, keep getting message
The device was drawing too much power and the USB port will shut down.

Hi
Is your machine connected to AC power? If not, connect it, and it should work. You may also try resetting the SMC.
If it still doesn't work when connected to AC, then the hub most likely is drawing too much power (i.e you have too many devices connected to it)

I have Ipad 2. When I touch an icon, a box forms around it and then I have to tap it twice to open. The box is messing up the touch screen and when I go into some apps they open, update then shut down.

I have an Ipad2. All of a sudden when I touch an app or select anything, a box forms around the icon or word and then I have to tap it twice to open it. So everything I do I have to touch 3 times. Also now when I open some of the apps, they open, update then close down. How do I get rid of the box.

You might have turned VoiceOver 'on'. See if triple-clicking the home button turns it off, and if it does then cahnge what Settings > General > Axxessibility > Triple-Click Hme is set to.
Otherwise your need to use the 'touch to select, double-tap to activate' process to go into Settings > General > Accessibility > VoiceOver and turn it off.
The manual (http://support.apple.com/manuals/#ipad) also says that you should be able to switch voice-over off by connecting to your computer's iTunes :
Turn VoiceOver on or off in iTunes: Select iPad in the iTunes sidebar. In the Options section of the Summary pane, click Configure Universal Access. Select VoiceOver, then click OK.
So select Configure Universal Access at the bottom of the Summary tab and set Seeing to Neither

Mavericks will only start in safe mode, then shuts down.

I think the new OS is trying to help me, but it's actually doing the opposite. Does is automatically try to start in safe mode after a hard shutdown or something? Every time I start up I get the spining wheel and a progress bar that takes 20-30 minutes to fully load. When it reaches the end the computer just shuts off. I have been having some problems with the Mac itself - multiple attempts needed to start up etc - but in 10.8 at least it would boot normally.
I can't even boot in the recovery drive or in Windows, because the safe mode boot begins before the keyboard is recognized, so Option does nothing. Any thoughts?
Edit: Tried zapping PRAM etc, still can't get the Option menu or avoid the endless progress bar of doom.

I installed the latest update today and now my computer wont startup. I just shows the grey installation bar then shuts down? Anyone know why?

Hi Guys,
I installed the latest mavericks updtae today.
When I restarted my computer it shows that its inslalling (grey startup screen with apple logo ad insallation bar).
When it completes the installation it just switches off.
When I restart it starts all over again and is now stuck in this cycle.
I cant even start up in safe mode?
Anyone else had this issue?

Fizz21,
if you search the discussions here, you’ll find many people who have had this issue.
You can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it reach the login screen now?

What is the best way to shut down an iMac that has frozen during a data transfer? The disk I was writing to will not eject. Stopping "copy items to" doesn't work either_ it is frozen as well. Is there a way to force eject the disk so I can shut down?

Some more information on the above: OS: 7.2
1. None of the shutdown commands would work so I held the power button down and received a prompt that asked if I wished to force eject the drive, I selected
the force eject and then shut down.
2. Just recently I installed an eSATA _ Thunderbolt_ port multiplier compliant PCIe card (Seritek Q6G) into a thunderbolt external chassis (OWC Helios) (seritek Q6G).
This freeze data transfer also happened when I connected a Firmtek 5PM external tower to the iMac via thunderbolt cable.
The driver for the seritek Q6G was installed in the iMac previous to connection of any of the devices.
Both external towers mount ok on the iMac but have frozen during data transfer.
The initial freeze was with the Firmtek 5PM which is (JBOD)_ I thought that might have had something to do with the freeze_ it being JBOD_ so next I tried the Mercury Elite AL Pro Q2- which is formated in RAID 5. But then froze too.
Anybody have any experience with this?
Maybe I need another driver?
Or maybe some update to my OS?
Any suggestions welcomed.
Thank you

Hello BDAqua, thanx for the suggestions. Before I saw this reply I tried to first quit the finder and then to relaunch the Finder but that resulted was a blank gray screen.
In the end I ended up having to power down the iMac.
Fortunately the RAID array that was "active" seems to be fine and also has a firewire 800 connection so I can use it_ just not with thunderbolt until this issue is solved.
I'm going to check in the Applications>Utilities>system log to see if any clues are evident_ thank you for the suggestion.
PS: Nothing of note was obvious as a root cause in the Activity Monitor though.
hmmm....I was told that the Helios and seritek card were compatable and that the Helios didn't require any drivers..it will be a drag if there isn't an easy fix for this since this new PCIe card from seritek is the first to offer port multiplier compatibility for eSATA to thunderbolt...since they are both new I'm hoping that an OS upgrade will be the fix (presently7.2)...we shall see.

Why is my iphone coming on only connected to a PC and then shutting down after 1 minute???????

Seriously need help. My phone is going crazy right after ios is installed. It turns on only with a PC and then shuts down after 1 minute? Never thought Id have problems with Apple.

I have had the same problem with my daughter's IPOD nano. Spoke with several technicians to try to fix the problem to be told it was a battery problem and to send it in it was covered under warranty. Was told that it was a problem with many of the nanos. I sent it in to have it returned with 1 week stating that it had "liquid spill or submersion damage indicated by the pink/red color of liquid submersion indicator located inside headphone jack." It has not had liquid or submersion damage and I can't prove otherwise. It works only if it is attached to computer. Will not turn on unless attached to computer. Maybe I am wrong but it it has damaged by water would it still work plugged into computer. Now I am out $200.00. This frustrates my because my ipod shuffle quit working 2 months after I got it. Thats why I bought the nano thinking it was better quality.

Fully charged the ipod works for 2 mins, and then shuts down, why?!

Fully charged the ipod works for 2 mins, gives the battery warning and then shuts down. I took it to an apple store, they said battery is fine, restored ipod to original settings and it still wont work! Help!

If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store. This time be more persistent.

When I go to my folders in the doc, the fan feature is not there. It stays in grid. I can click list. Once in list (and list only), the fan option returns. However when I click it, it just goes to automatic. My folders just have 3 items or less in them.

Quick note...when my son logs into his user account, the fan feature pops right up and works fine. Thanks!

Is the Dock on the bottom or the side? Fan is not an option with it on the side.

Hallo Wein and welcome to Apple Discussions ,

Well try this and see if it helps:

If so it's U28 on the bottom of the board. The shim fix will work for a good time but a permanent repair is to have the chip resoldered. $40 at Superior.
the first problem was that date/time will lost,
That's because the power is interuppted.
is the problem the Backup battery? And how to change?
There is no backup battery or PRAM battery like in the PowerBooks. There is a .22 Farad super capacitor that will hold settings for a while but not long. Meant to allow a battery change.

Re: Equium - Not booting up only the fan kicks

Hi, I need some assistance with my laptop.
The power, and the battery light comes on when I switch laptop on at the mains.when I go to switch the laptop on only the fan kicks in it's not booting up at all.
Can anybody help?
Thanks
dean

Hi
What Equium notebook you have exactly?
Its really hard to say what is causing this issue but maybe its a hardware problem and you need professional
But at first try this workaround:
Remove the battery and AC/DC adaptor, then wait up to 1 hour. Next connect both devices again and try to start the notebook. Maybe it will work
If not you should contact the nearest authorized service provider. The technicians should check your notebook for hardware problems.
