My iMac sometimes will not switch on.
I have a late 2012 27" imac. Its always plugged in to an APC500CS UPS but isnt always left swithced on. I frequently have to reset the SMC as the MAC won't switch on, is this a common problem or is there something I can do to prevent this from happening?
Thanks for your reply. I thought it might now be okay as it was in sleep mode all night and woke up this morning. However, left it in sleep mode over lunch today and when I came back it had shut down and had to reset SMC to restart. Turned off Time Machine yesterday in case it was something to do with external drive.
Here's the etrecheck report:

My iphone 4s will not switch on. Supposidly it has been "charging" all day and stll it does not have enough life to switch on. Rang Apple this morning and they will replace the phone under warrenty free of charge. Only problem is with this being my first Apple product i didnt realise my phone did not automatically back up on itunes or icloud as i had to set this up.
Now i am trying desperately to get my phone to switch on so that i can save all of the baby pictures of my 7 month old son and its not working. i have tried to reset the phone but it does nothing!!
Can anyone PLEASE help as i am very upset and do not want to lose these precious memories?You cannot get Applecare plus now.
It is unlikely that they will replace as it is damaged. The only way to find out is to make an appointment at the genius and and see what they say. -
I seem to be having a lot of connectivity issues my iPad. It takes a long time to load and sometimes will not load a page at all. I seem to be having issues with streaming in that it will play a song and just stop. It seems I have to turn it completely off and restart.
Anyone had these issues?Settings > General > Reset > Reset network settings

My bluetooth keyboard (Macnus brand - bought recently in Thailand)(similar to Mac small keyboard) will pair with my iPad using code 8310,and is recognized by my iMac but will not pair?
There are very scant instructions with the keyboard and no mention of any code (the code was prompted by my iPad).
I have followed the instructions but it still will not pair with my iMac!
Can anyone help please?
My iMac is 20 inch Mid 2007 OSX10.9.1 4GB RAMHi All, thank you for you suggestions. I have been unable to find any website for the maker, but have looked at several Thai/cambodian sites incl <http://www.buycoms.com/Article/8435/index.asp> which mentions the keyboard being suitable for tablet or windows. No mention of iMac! although the box is branded to indicate Mac compatable.
I'm thinking that maybe it just will not pair with an iMac.
Ill keep looking for the maker website, which might come on later in the future? maybe?
thanks again. -

Experia z1 screen will not switch on
hello
im in need of some serious help.
myy Sony Experia z will not switch on and i dont know why. i have tried all forms of ways reccommended on the Sony website and also tried using PC Companion to use the software update for phone service but it does recognise my usb conection.
please help me or recommend a way for me to fix this problem as soon as possible.
P.S i took my phone to mtn and they want to charge me R5500 to fix up this problem while my phone is still under warranty . this is unacceptable.
i would prefer direct aid from Sony.
Thank you .Try to perform a system repair
Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process
If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
To add this is a user support forum so the direct aid you speak of will be from your local Xperia care team http://www.sonymobile.com/global-en/support/contact-us/

How to update photoshop CS2 / iMac OS10 will not support
Exactly what version of Mac OS 10 do you have?
And, if Photoshop is not supported, you will need to update/upgrade/pay for a new version of Photoshop. CS2 has not been supported since Snow leopard I believe (10.6):

My 'slide to unlock' sometimes will not unlock when trying to answer a call. How do I stop that happening?
Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)
Note: You will not lose any data. -
i have a mac book pro with os x 10.5.8.......sometimes will not load google or yahoo, or any other search engine, but will load regular sites.....why is this?
Check System Preferences - Accounts
Choose you account - login items: If iTunesHelper
shows up - remove it it will prevent re-installation.
It did not have iTunes in the list, just mail and iCal alarm. Deadlines and emails are vital in my home office.
Now that I think about it, adding Mail to the list was the only thing that I had changed to the computer when this happened, but I can't imagine how that would alter permission to install on the OS.

my i-phone 5 s will not switch from portrait to landscape
If you swipe up from the bottom of the screen it will bring up the control panel. Check to see if the lock icon with the circular arrow is selected. That will lock the rotation of your screen.
Just make sure it is deselected -
