My MacBook will not log off and will not switch back on

I tried to log out this morning and all I got was the blue screen. I cannot switch on again, what should I do

Have you turned it off? Hold the power button fo 10+ seconds and it should turn off. Try to start it then. If no success, post back.
Ciao.

HT5538 Hubby's phone has switched itself off and won't switch back on. It has been charged but nothing works.

Hubby's phone has switched itself off and won't switch back on. As far as we know it's fully charged, can't check as got a blank screen but does buzz when charger is plugged in. Has been left on charge for quite some time. As you will gather, I am sending this on his behalf.

A reset may help. Tap and hold the Home button and the On/Off buttons for approximately 10-15 seconds, until the Apple logo reappears. When the logo appears, release both buttons.

I turned my iphone 3g off and it wont switch back on

I turned my iphone 3g off during a movie and it wont switch back on, i tried turning it back on resetting it and whatnot but it comes up with a blank white screen and then turns back off. I tried recovering it but it gets stuck at 3/4 and then freezes.. ive looked through the forums already but nothing helped, what can i do?
I never had WiFi sync and it has never been jailbroken.

Could be short in the iPhone charging port. Clean the charging port with a clean dry toothbrush. See if better. If not, iPhone 5 has Warranty. Make Genius reservation or set up service and take or send to Apple for resolution.

Q5 turned off and won't switch back on

Hi,
My friend went on holiday and the Q5 he was turned itself off and won't turn back on again.

Connect your Q5 to the OEM charging cable. Let it charge a few hours.
Then, with it still connected to the charger,
Restart: Press and hold the upper edge power button about 20-30 seconds, ignore the 3-2-1 timer and hold until the screen goes black and you see the red LED.
Do you see any LED or screen activity on thte deivce?

Macbook Pro - WiFi turns OFF and won't turn back ON

Hello,
this is my first time posting something on this forum; I will be as detailed as possible. I bought a Macbook Pro back in 2011 and It came with Lion OS. Last year I upgraded it to Mavericks and so far it has been a nice experience. However, in the past week I have experienced a very strange and irrating problem with my macbook. While doing work all of the sudden the WiFi would turn off and lose all connection to the web. I attempted to turn it back ON by clicking on the wifi signal icon but something weird occured, it was still 'ON' according to my mac and the only option available was to actually turn it OFF, so i clicked on it and the icon would go empty with no curvy lines (i attached a picture). Then i clicked again on the icon to turn it back on, however, as was doomed to remain in this state cause no matter what I tried.. the wifi will remain off even after clicking on the 'turn wifi on' option multiple times. I tried going to the assist me option under network preferences and I obtained multiple results with no fix. I tried sending my mac to sleep though at first seemed to fix the problem.. the wifi inmediately went back to being off and wont catch a signal. The only thing that fixes this is a fresh restart which is annoying and unacceptable...this is really annoying and I need a solution asap because this problem is become very frequent (once every 2 hours)... any help will be appreciated it.
I attached 2 pictures and the console log when this happened.
1. A picture of my assist me window before i sent it to sleep, shows the WiFi on the left with the 'Failed' (which confuses me). it also shows the wifi icon empty ( like it was off) but the computer shows as if it was on and would ask you to turn it off... weird?
A second picture after I sent my mac to sleep. Though it seems like there was no wifi signal available, the router was on and literally next to my mac...but my machine wont catch up the signal. (other devices were connected to the wifi and have no problem with it).
Here is the console log right before and after my this problem occured:

Thank you for your detailed troubleshooting attempts. Very helpful. Sorry, I cannot read "logs." My eyes just glass over on those things. Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled." Have you tried the "Automatic" setting? Run the diagnostic test? Results?
Try the basics first:
 Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Macbook air randomly shuts off and won't turn back on

I have a 2011 Macbook Air that was given to me by my sister. She told me about a year ago she spilled water on the keyboard and it stopped working for a while. She took it to apple and they told her it was going to cost 700 dollars to replace so she decided not to. After a while the laptop randomly turned back on and started working fine. I ended up getting it as a free gift and it was working perfectly fine for about a month and a half until recently it randomly shut off on me. After it shuts off, it wouldn't turn back on through pressing the power button I left it alone and after a day it randomly turned back on and worked like normal. After about 15 minutes of use it randomly shuts down and won't turn back on. I tried resetting SMC to no avail. It randomly turns on for about 15 minutes before it feels like it gets slightly hot and shuts off. Any help will be great!

Try running an Apple Hardware Test:

If you find you can't, make an appointment at an Apple store genius bar. The evaluation will be free and then you should know what the problems are with your MBA.

Everytime I log in to my computer firefox comes up in "Work Offline" mode. Even tho I uncheck the box the next time I log off and in it's back in the "offline" mode. How can I stop this?

Work Offline is always checked when I log in to my laptop. I have to uncheck it to get to the internet. I don't usually want to work offline so this is very annoying

You can try this:
Create a new Boolean pref with the name network.manage-offline-status and set the value to false.
Right-click on the about:config page to open the right-click context menu and use "New > Boolean" to create a new Boolean pref.
Name: network.manage-offline-status
Value: false

My iMac20 powers off by itself and won't switch back on

I'm sorry this is a bit of a saga but I'm at the end of my tether with so will be really grateful if anyone has any experience of this issue and can give me some help?
The problem started in May when, after an hour or so of use, my iMac 20 suddenly started to turn itself off and wouldn't turn back on again until the following day. This happened around half a dozen times so I took the machine to the local Apple store and was told that it was probably the thermal trip and if I removed the power cord and left it disconnected for a while, it would power up again more quickly. That evening when it cut out, I followed the advice I was given and removed the power cord from the back of the machine but it made no difference and the machine would not restart until the following morning. Back to the Apple store I went and this time they took the machine in to the workshop; a day or two later I was told that they had cleaned out the fans and tweaked some software and had run it successfully on the bench for several hours with no problem. After paying £49, I collected the machine, took it home, ran it for an hour or so and off it went again and as before, refused to turn on. Back again to the Apple store; "Had I reloaded the operating system?" Well no, because I hadn't been told that I needed to. And anyway why would I... surely the thermal cut-out was a hardware issue? The response was that the problem was definitely software-based and nothing to do with overheating or a faulty power supply unit (which was/is my favourite candidate for villain of the piece). So off home I went, backed up my stuff and ran Disc One successfully and started running Disc Two. After about 20 minutes into Disc Two the machine did its usual trick and powered off, and I went looking for a bottle of wine.
Back to the Apple store. The guy controlling the 'guest list' for the Genius Bar said that if I wanted to return the machine to the workshop that day it would be considered a new incident and there would be a further charge for any repair work. However, if I made a fresh appointment (for a couple of days later) then the work would be done as part of the previous 'repair'. Somebody at Apple really needs to look at the way the stores deal with dissatisfied customers.
So, Saturday the 11th of July arrives and I head back to the Genius Bar for my free appointment. I explained to a very helpful guy that this is my fifth visit and I would like to get to the bottom of the problem. He referred to the tech person who dealt with the original workshop repair and she came out to explain that the issue is caused by 'something' lurking in my Library folder and that if I wipe my hard drive and re-install the OS from scratch but without the Library folder, the problem should be solved.
I spent Sunday wiping the hard drive, running the OS discs and then reinstating my iTunes, photos etc and waiting for the machine to turn itself off - but it didn't! I left my external hard drive returning all my files and documents overnight and when I woke up on Monday, everything was still up and running... bliss!
Then, this afternoon, after downing loading a music file in flac format, I found that it wouldn't go into iTunes without the help of Fluke software. I downloaded the Fluke stuff and then as I dragged the flac file into iTunes - boof! The machine went off and won't switch back on again.
So finally... has anyone seen any similar behaviour with their iMac and was it caused by software or hardware? And if it is software that's causing the problem, why can't I switch the machine on again immediately?
,

Amsys plc, the company Apple uses for off-site repairs returned my iMac20 today and the accompanying advice note states that the fault was resolved by replacing the power supply unit. I am really grateful to Apple for finally getting to the bottom of the problem, particularly as the repair was done free of charge, although I had already paid £49 for a useless workshop investigation at the Kingston store. The service given by Amsys was exemplary... the collection and return of the machine was carried out at the times promised and whenever I contacted the company by phone, each person I spoke to seemed to have knowledge of the repair without having to refer to the case notes (and none of the 'press 1 for service, 2 for sales...' rubbish).
So once again BDAqua, many thanks for suggesting I call Apple... it's just a shame that the staff of the Kingston store refused to accept what was obvious to me.

After updating to 10.10.3, now my Macbook Pro will not stay logged in. I log in after restarting, and it will stay logged in for 3-5 seconds then immediately log off and go back to the login screen. Any help?

After updating to 10.10.3, now my Macbook Pro 15" (mid-2014) will not stay logged in. I log in after restarting, and it will stay logged in for 3-5 seconds then immediately log off and go back to the login screen. Any help?
By the way, I also updated my Macbook Pro 17" (mid-2009) and it seems to be running fine, though I haven't tried to restart it and log in. I'm afraid I won't be able to get this one to work either if I do.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Does it power on if you plug in the charger?
But to be honest I see in your description it says 'Late 2011' so there is a good chance you have warranty right, I would take it to Apple store and let them sort it out

Hey saintbless,
Thanks for the question. The following article outlines troubleshooting information for iPod nano. While it mostly refers to the 6th generation, most steps apply for your model as well:
iPod nano (6th generation): Hardware troubleshooting
http://support.apple.com/kb/TS3474
Will not turn on or screen remains dark
- Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
- If iPod does not turn on after ten minutes, try resetting the device while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Volume Down button for at least eight seconds or until you see the Apple logo appear.
- If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
- If the screen remains dark and will not turn on, then your iPod may need service.
Thanks,
Matt M.

My phone just turned off and will not go back on. my top lock button has been broken for over a year. Help!

my phone just turned off and will not go back on. my top lock button has been broken for over a year. Help! I have tried plugging it into wall unit and computer but my home button just doesnt do anything!

It seems that year long delay from having your lock button repaired has finally caught up to you. Sounds like you have some damage to your phone that requires repair/replacement. Take it to a Apple store or contact Apple Tech Support.
