OK to leave screen on for hours?

Thinking of using my iPhone 4 as an alarm clock, with a nifty little stand and all. Is there any harm in turning the auto-lock off and having the screen be "on" for 8 or more hours at a time? The display probably wouldn't change much if I just had it showing a clock face. I'd have it plugged in, so battery wouldn't be an issue (right?). But would I harm the screen, damage its lights, cause burn-in, or otherwise hurt the phone?
Thanks!

By default the printer is set to go into idle mode after 5 minutes. After the printer is in idle for an additional few minutes, then the unit goes into Auto-Off.
It is not a problem to allow the printer to stay in idle for extended periods of time. The unit will only maintain enough power in the circuit to power the little LEDs and maintain a packet communication with the router if wireless.
If you desire to change the time frame or turn this feature off, then check the document located here. Hope this helps.

Has anyone had problems with the screen freezing for hours?

Yesterday my phone kept freezing when I went to unlock it, after 5 minutes or so it would then go to the code unlocking screen but last night my screen frooze for 12 hours until it finally ran out of battery and shut down. When the screen freezes there is no way to force a shut down...can anyone help?

If the screen freezes, reset the phone - press both the home and sleep/wake buttons until the Apple logo appears (~10 seconds). If freezing recurs frequently, restore the phone. See Appendix B of the User Guide:

Payment being processed,please wait,placing order- Same screen message for hours

Hi. I had the free 30 day trial of cs6 which was about to end. Decided to buy it online , pay monthly option. I have the message 'payment being processed , This may take a few minutes. Please do not click back or reload this page to avoid duplicating this purchase. Placing order...please wait'. This is going on for hours. I have a toshiba satellite laptop. Windows 8.1 . Any help would be appreciated.

Here's our current problem: The screenshot shows that we have two files, each has an Inbox, etc. The one with our correct properties is empty and the one designated local has all our email, etc. Neither one can receive email from Verizon's server and I've been unable to delete the empty duplicate or change the local's properties to the correct values.

I have not been able to access pics on iphoto. When I click on iphoto it begins loading and seems to be stuck. I can leave it loading for hours and nothing happens. Need help grandkids pics are on their.

I have not been able to access pics on iphoto. When I click on iphoto the program starts loading and continues to spin.What can I do to remedy this problem?

Best option: Restore from your back up
Next best: Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
Least best: http://docs.info.apple.com/article.html?artnum=107947 has details on how to recover the files from your Library and start over.

Screen frozen for hours when trying to login to guest user. How do I switch off?

How to switch off when totally frozen for hours

It wouldn't do that unless they registered an iOS device for iMessage. An iPod Touch, iPad, or Mac. If they don't want their messages to go to that device, tell them to turn off iMessage. The only other way to stop it is for you to turn off iMessage entirely (not to mention anyone else with an iPhone who might try to send them messages).

Whenever i start my macbook pro the screen remains gray with the apple symbol and the circle timer below. The screen stays this way even if i leave it for hours.

When i turn on my macbook a box appears telling me i need to restart my computer (in different languages) and in order to do so i have to press on the off button for a lil while. Even after doing this the same box appears and it never restarts correctly. This box appears every single time. I rarely turn my computer off. I just place it on sleep mode and restarts it only when i get prompted to. I brought it to genius and they couldnt figure out what the problem is so i was told it needed to be shipped to get fixed. I didnt have anything backed up. All i want saved are the pictures because i went to 2 events where i was the assigned photographer and i didnt get to save it to an external memory. Genius said that when shipped i cant give instructions like make sure to save the pictures and if they are unable to, call me if they should go on with the process. I was wishful thinking that to fix the problem they might not even have to touch the pictures memory part. I brought my MBP back home hoping it will miraculously starts and id be able to back it up but now all it does when i turn it on is the screen remains gray with the apple symbol and the circle timer below. The screen stays this way even if i leave it on for hours. Please help me fix this!!! cant i really specify to the technicians at apple to please make sure not to erase the pictures? Is there no other way to turn on my mac? I only need it to work ones.

There is no limit to the number of times you can re-install Office on the same computer.

W530 will only boot after being left off for hours

I just purchased a Thinkpad W530. it has worked beautifully other than one major problem: it won't start up after a shutdown unless I leave it off for hours. I can turn it on after being off and it works just fine, but if I turn it off I have to almost wait overnight for it to turn back on again. I hit the power button, the green light comes on for a few seconds and then it turns off again.
I've tried booting with just the AC adapter and just the battery. I've also tried unplugging both and holding the power button for 30+ seconds and then plug it back in and it does the same thing. I ran the hardware diagnostic test provided by Lenovo when I'm able to actually get it to work but the results (albeit it's nowhere near a comprehensive test) appear to be fine. I also tried changing what slot the RAM is inserted in.
Also, it has never shut down or anything randomly and it won't turn on no matter how long I had it on so I don't think it's a heat related issue. I had it on for under a minute yesterday morning and then turned it off and it wouldn't turn on until this morning.
Thanks in advance for any ideas!

I think it IS a heat issue, but not overheating. You probably have a defective chip on the motherboard (part of the starting circuit) that only works when cold. I assume it has a warranty. Now is the time to get service.

I am trying to upgrade Mac OSX from 10.7.4 10 .7.5 .But, the grey screen is coming for hours. What should i do?

i am trying to upgrade Mac OSX from 10.7.4 10 .7.5 .But, the grey screen is coming for hours. I pressed the alt key and was taken to options viz. Restart to install MAC again, use time machine. I don't have back-up and so restarted to install MAC again. Can i cancel this now. I want my data to be secure. What should i do?

If you cancel an install there's no telling what state it will leave your Mac in. Let it finish or fail.
Then get a disk, it can even be a pocket drive if it's large enough and back up all your own data.
After that, boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X

Disk Utility
First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X.

Mac Book Air shuts down completely if I close the cover and leave for hours. Message: you shut down your computer because of a problem. Any thoughts what is happening?

Mac Book Air shuts down completely if I close the cover and leave email running. Is n't it supposed to just sleep and awaken whe the cover is reopened? Instead, I have to boot it. Any idea what the problem is? I am unaware of any problem, just close the cover for safety.

Well I don't know anyone that closes the cove and leaves it for Hours... But try going to System Prefrences > Energy Saving > Uncheck Put Hard Disk to Sleep.

Next time an app update gets stuck try a reset. Press and hold both the home and power buttons for10-15 seconds till the Apple logo appears. Then release both buttons. Wait till your iPad starts on it's own. Try now. Also YouTube is still available. If you can't find it the the app store go to the bottom of the app store page and tap purchased. All your deleted apps will be listed and you can reinstall YouTube from there.

If this message appears - did you try to restore it with iTunes?

Unfortunately do not know the operating system since I never updated anything and I can't get in to it.
Thanks for your assistance.

If you want to preserve the data on the boot drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Hello, my mac book air won't update. Every time i try it goes onto the purple starry screen and stays that way for hours, so i just have to shut it down. I have deleted a lot on my laptop so there is enough space, please help?

I believe that system has a hall sensor on it to detect when the lid is closed so it can put the system to sleep and/or disable the monitor so it can be used with an external monitor only. If the sensor is marginal or has a bad cable, it may intermittently cut the monitor on and off, and may likewise put the system to sleep. One way to check would be to plug in an external monitor and if the laptop's screen cuts off or doesn't show up, start using the trackpad and press on a non-typing key like the shift key. If the external display suddenly pops and becomes active while the laptop display remains black, it's probably a problem with the sensor or the cable/connection. You might be able to fool the sensor into kicking on and off by moving a magnet over it. It's located on the left had side of the base with the unit opened up, and right over the audio output plug.
I know of some people that put a small magnet right over the hall sensor's location so the laptop display turns off and they use the system with an external monitor, keyboard, and mouse. If fooling with magnets, make sure they're small and don't get them close to the hard drive because a strong magnet can wipe them out.
I don't know if this will help you much, but it might.
