My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me crazy as the screen keeps going blank and I have to constantly put in my pass code every few seconds. Can someone help me out please. The pass code lock is set at 10 minutes but it's happening every few seconds :(

I've run into the issue and it seems to be related to an app not fully supporting the iOS you're on, the reboot doesn't usually solve it.
I've solved it in the following manner(s):
1) Backup the device to iCloud, then erase the iPad (Content and Network Settings).
2) Setup the iPad and choose to restore from iTunes/iCloud Backup (wherever you backed it up)
3) Perform any software updates
I have not tried simply performing the software updates (which may fix it, but if it doesn't you won't be able to perform the above steps).
Enjoy.

Grey screen boot problem keeps happening after fix

Recently my desktop mac (originally snow leopard upgraded to mavericks, if this information is important) failed to boot and was stuck on the boot screen with the apple logo and the spinning wheel.
I researched how to handle this (youtube being the most help) and managed to fix it by reinstalling mavericks. However, the problem happened again this morning and once again I had to reinstall. I have verified everything through disk utilities and nothing seems to be in need of repair.
Would anyone be able to tell me what the problem could be and if it is anything I could fix myself rather than sending it in to repair?

I have the exact same problem ;) and cant fix it nyself im reinstalling macs right now, if not il try to install snow leopard again, thats the only solution i have right now since all the attemps to fix failed because the problem keeps happening again

My mac hung up while installing an update. It took hours and still did not complete the update. I restarted my mac. Upon turning it back on, a wheel has been spinning on a grey screen. I tried to reinstall OS X from utilities, but encounter an error. Why?

Hey Manaskala,
First point of call on all grey screen issues is the following:
http://support.apple.com/kb/TS2570
Given this issue has appeared after a software update, I'd advise you do the following instead though:
1. Get an external hard drive, with enough space to put the entire hard drive of your Mac onto. Make sure you've safely copied any data you have off of it, as the next step will erase it.
2. In the recovery HD of your machine, use Disk Utility to format you EXTERNAL hard drive with the partition table as GUID, and the format as Mac OS Extended (Journaled).
3. Get out of Disk Utility, and click Reinstall Mac OS X.
4. When asked where, choose to install onto your external hard drive.
5. When the download and installation is complete, your Mac will reboot into a clean fresh setup screen. Make your user account an administrator, and make up a name and password; I use 'Test' and 'test'.
6. Your machine is now running from the external hard drive, not the internal hard drive, so don't be alarmed when you don't see your files.
7. Open the finder, you should see 'Macintosh HD' in the sidebar. This is the internal hard drive of your computer.
8. Open Macintosh HD, and copy out the following folders into a new folder on your desktop:
-Users.
-Applications.
-Library. (This only needs to be done if you use 3rd party software that saves things in the /Library, do a quick google and see if it does e.g. Photoshop, Protools).
9. When these have copied (it'll take quiet a while), you can now use Disk Utility to erase your hard drive. Don't erase Macintosh HD but the ENTIRE hard drive on the inside of your Mac, and as Thomas A Reed mentioned, there was likely an existing issue on your HDD so please go to Security Options and choose 'Zero Out' before clicking erase. This will rebuild the partition table which was a possible cause of the failed update.
10. Reboot the machine holding 'Option', go to recovery HD.
11. Choose 'Reinstall Mac OS X', this time onto your INTERNAL hard drive.
12. When this is complete, make another admin user called test and password test, like you did last time.
13. Run Software Update from the  menu of your Mac.
14. In the Finder, you should see your external Hard Drive. open it up, inside that you should see your desktop etc, and on the desktop will be your folder containing Library, Applications and Users.
15. Go to Finder up next to the  and choose File -> New Finder Window.
16. In your second finder window, open up Macintosh HD (through the Go -> Computer menu), and go to your Users folder.
17. Open the Users folder in your first finder window, and copy your user folder (has your name on it) into the second user folder (the one inside Macintosh HD).
18. This might take a while.
19. When complete, go to System Preferences -> Users and Groups and unlock the padlock.
20. Click the '+' sign, and make a new administrator user.
21. Now, the fun bit. Note the name of your user folder you copied, e.g. 'Nathan', containing all of your stuff. Note the difference between your user folder (has your name on it) and the Users folder (contains YOUR user folder, guest folder and shared folder).
22. Make the ACCOUNT NAME of your new adminstrator user the EXACT name of your user folder (normally lower case and without spaces), this is case sensitive folks. Your full name can be whatever you want, usually your full name.
23. Then click create. You should be informed that a home folder with that name in it already exists in the Users folder, would you like to make your new account from that folder? say YES!
24. When this is complete, log out of the Test user, log into your new account we've just made, all your stuff should be there.
25. ???????
26. Profit.
There's a few little bits that may need to be cleaned up afterwards, applications folder from your external hard drive should replace the applications folder on your internal hard drive, if the previously mentioned /Library folder contained important goodies then that should replace the /Library folder on your new Mac.
Hopefully that will help you out, straight after that is done make sure your stuff is there, erase your external hard drive and turn on time machine!

Macbook pro screen stuck on grey screen while system working

Hi everyone. I would like to share with you a very annoying problem I am experiencing with my macbook pro since yesterday.
It's a 15" Intel Core 2 Duo 2.4 ghz (late 2007).
I should start by saying that my macbook was already having, since months, a problem at the display which was kind of flickering at any movement. The Apple Center told me I should have replaced the entire display because the problem is due to a cable which is located inside the display itself and Apple does not provide this kind of repairs. Anyway I decided not to replace the display (which is a very costly operation) since I was very often using an external monitor without any problem.
Yesterday while I was working (without external monitor), the display suddenly freezed with a kind of blinking light. I forced the shut down by holding the START/STOP button for some seconds. Since then I tried to start again many times: I hear the standard startup chime, the computer normally loads for a couple of minutes until the screen get freezed on the grey screen with apple logo, I suppose right in the moment the desktop should appear.
The strange thing is that I discovered, after several attempts, that while the screen is freezed, the computer is normally working! It is regularly connected to the internet through my router and, even if I cannot see anything but the grey screen, when I press the STOP button and then the "ENTER" key it normally goes off.
I tried to connect it to an external monitor as I usually do, but this time it did not work at all. I also checked the hard disk by starting in target mode and found no problem in it. The hard disk and the system on it are OK.
I found on the web that late 2007 macbooks have a well known problem with geoforce video card and that apple is even providing free of charge repairement.
So I thought it might be my case, brought the macbook to the Apple Authorized Service Provider and asked about it. The people there told me that the Apple policy on the replacement is very strict and that classic symptom of geoforce failure is a black screen and not the grey screen with apple logo. They said they will check, but gave me very little hope. They told me that a logic board replacement is worth at least 600 euros which I think is too much for a 2007 computer.
Did anyone have this kind of problem? Do you find more likely to be a problem due to the video card or something different?
Thank you for any help.
Antonio

Holding the shutdown buttom down for several seconds solved the problem. When I booted my mac again, it continued with the update. However, do you guys think my mac have taken damage of this?

My new MacBook Air keeps shutting down the screen while I use it

My new MacBook Air keeps shutting down the screen while I use it and has to be rebooted. I took it in to the Genius desk at my local store, but they couldn't find anything wrong and said that they have never seen this problem before.
I Spoke to the IT support guy at work. He has the same problem with his new MacBook, but not with his older one. He suggested that it is a software issue with all new MacBooks and is connected to the timing of it going into sleep mode. Does anybody have a solution? Apple doesn't seem to have one.

Try a SMC reset.

What operating system version, and do you have any backups of your data off the machine? TimeMachine? Option Key bootable clones? Storage? DVD's?
A reinstall of the operating system may be in order as a last resort, so if any of these steps on these links get you into the machine, make sure to backup your personal data (Music, Pictures, Documents, Movies) off the machine to a non-encrypted powered external drive regular storage drive (not TimeMachine as it might be corrupted too) and disconnect as soon as possible.
Good Luck and report back all what you tried.
Also report what change occured before this tragedy happened, was there a Software Update? A EFI firmware update? Etc.

A few thoughts and experiences after a few hours using my new ThinkPad E440 with Win 8.1

After waiting 36 days for my new ThinkPad to arrive, I guess I'm just "eh" about it after using it some. Here are some of my thoughts, opinions, and experiences I've had after using it for a few hours... Hope this helps other people.
I should not be surprised because I read all the reviews, but the touch pad really sucks. I hate everything about it, the way it clicks - it's so loud and clunky! - and it's insensitivity (and I adjusted this to be more sensitive). Thank goodness for the track point. I love that thing.
The touchscreen stopped working after a few hours of use. After I rebooted it came back. Is this a bad omen? Or did I inadvertantly turn it off? Is that even possible? I am new to Windows 8 so anything is possible.
The touch screen, when it's working, is not very responsive. It's MUCH LESS responsive than my Samsung Galaxy Note 2 Android phone or my LG G Pad 8.3 tablet. This is very disappointing.
I ran the hardware scan that is in the Lenovo Solution Center and got a warning under the category "Local Connection Test". I looked at the list of System Events and it's very long. The first application error event name is MpTelemetry. Response is "Not available". The next one is "PnPRequestAdditionalSoftware". Response is "Not available". And the list goes on and on and on for pages. I have no idea what to do about this or what it means.
Also in the Lenovo Solution Center, under Software, there is a Critical Alert that says I never updated Windows. But I did when it prompted me to while it was first booting up and it was updating and installing things. Where it says "To update your operating system, you must run Windows Update", I click on the Launch button and it takes me to Windows Update where it says No Updates are Available. Go figure. It also says there have been 9 Windows updates made to the computer. I guess I'll have to just always ignore that Critical Alert.
In the system tray, it says "ThinkPad OneLink Dock Detached!". I don't have a dock... So, yes, that's true, it is detached. I'll have to hide that one.
I realize there is a Lenovo Recovery Partition on the hard drive but I would really like to create a set of recovery disks before I start customizing this thing, installing apps, and moving my files over. I can't find anything that tells me how to do it. Under the control panel, there is the Recovery icon. The only choice there for creating recovery media is to create a Recovery Drive, not disks. I'll post a separate item to get information on this.
On the positive side, I have had it in my lap the whole time and it's not gotten too hot for my legs. That's a big improvement on my old Toshiba Satellite Pro.
This locating the Fn key to the left of the CTRL key decision must have been made by someone smoking crack. Why would anyone in their right mind want to do this? We've had the CTRL key on the outer left edge like, FOREVER, why move it now?? This will be something that will take me a long time to adjust to - if I ever do. I use the CTRL a lot for cutting, pasting, and formatting things in Excel and Word. It's going to be a battle. I wonder if any software exists that allows you to redefine the keys? Speaking of location of keys, I keep hitting the Page Down key when I want the Page Up key. I'm used to the Page Up key being above the Page Down key instead of to the left.
After being told here in the forum that the fingerprint reader was not an option in the US I am pleasantly surprised to see one on my new ThinkPad.
I use the right-click on my mouse often. For example, to open a link in a new tab instead of switching to the new URL. For some reason, when I click on the right part of the touch pad when the mouse is located over a link, it just opens the new URL instead of giving me options for opening the URL. I'll have to figure this out.
So anyway, I guess that's more than a few things... hope this is useful to someone...

You can change FN and CTRL key in the BIOS

HT5278 I lost a screen after this update, does anyone know how to fix this?

I lost a screen after this update, does anyone know how to fix this? Update iOS 5.1.1 It used to have three screens with icons on them, now only 1.

No offence, but as with quite a few others, my Iphone stopped charging on mains after iOS 7.0.4 update too.
Not sure you can categorically advise that "it simply is not a software issue" when so many different people are having the same symptoms after updating their iOS Just have a quick Google!
Luckily my (original Apple) cable will still allow recharging via USB to a laptop. So, process of elimination would point to a bricked charger that was working faultlessly up until the iOS 7.0.4 update was applied. Seems quite a stretch to be a coincidence.
Look forward to an explanation ..... and an update? ......

Gnome-shell and its CPU hog after a few hours of using

(Yeah, I know there was many threads like mine, but most of them are about old bugs or people who have hardware acceleration turned off; I use GeForce G210M and my system is up to date (systemd and all that stuff))
I have to restart Gnome Shell after a few hours, because it starts to constantly use 30% - 40% of CPU.
Is there any patch for this?
Are there any debug tools to see if it's not some badly written extension? I use only a few of them, so I guess that's not the problem.
I already use ulatency and verynice. Would it be safe to set gnome-shell as 'runawayexe'? IDK if it'd restart itself. Now I have it in goodexe.

Are you sure it is the Gnome Shell? (Try running htop and monitoring the processes)
Try disabling all your extensions and re-enabling them one by one to see if any have memory issues.
Another possible issue would be extensions that cause updates all the time. For example the netspeed extension constantly updates with your internet speed.

Unable to boot Z10, stuck on loading screen at 99% after a few hours.

Hi, I am unable to boot Z10, stuck on loading screen at 99% after a few hours. I did not try to update, nor load any other OS versions. Running a Bell Canada 10.1. Tried to pull battery, leave phone boot for 5 hours, still stuck on 99%. I tried plugging it in BB Link and computer will not recognize it.
