Screen auto dims and after about one second, it sleeps. If you try to catch it and undid the screen during this time, it freezes and you have to hard reset.

If you leave the laptop untouched, it will auto dim the screen.
About one second after autodim, the screen will turn off.
If during that one second duration, you try to undim the screen (by touching the touchpad, for example), the laptop will freeze and the only way to turn it back on is by holding the power button.

1. System Preferences > Energy Saver
    Press the "Restore Defaults" button.

I have a macbook pro13" 2009 with a Bootcamp System Mountain Lion/Windows 7. If I work in Windows 7 I do not have any problems, but if I work with MacOS my Image freezes after some time, with quicktime immediately and I have to hard reset the system.
Can anybody tell me, what I can do?

I have already updated everything. But it did not help.

Playback in Preview window stops after about 1 second

Hi,
When I hit the spacebar to view the clip in the preview window, the playback stops after about one second each time. It goes smoothly, then after one second, it stops. I can however drag the slider across the time line and there seems to be no problems.
I'm sure I have a powerful enough computer, so I don't think it's something to do with ram (I have 6 gig ram, Vista, triple core processor, good graphics card... brand new computer bought yesterday)
I'd appreciate help with this.
Thanks!

I'm not sure what you mean... I am importing from a DV tape which was recorded onto by a MiniDV Camera. When I plug in the camera to my fire wire, Windows gives me the options of AVI and WMV format (I am not sure which one to go with by the way, but WMV format seems clearer and 5 times smaller too.. why is that?)
Any ideas?
Thanks again
EDIT: Also, I borrowed some video files on the net and premiere does the exact same thing- stopping after one second :/

TS3623 If the screen says Unable to Sign in-Apple TV can't connect to the server at this time. please try later. I've been getting this reading for about a week

My screen has been reading for about a week: Unable to Sign In, Apple TV can't connect to the server at this time. Please try later. What do I do to get pass this screen. I purchased a movie series season from HBO and I can't watch it because I can't pass this screen.

Hi Kailik Hunter,
Thanks for using Apple Support Communities. This article has some steps you can try if you're unable to sign in to your Apple TV and continue with setup:

http://support.apple.com/kb/ht1551
If you are still having trouble, you can try to reset your equipment by unplugging Apple TV, your television, your wireless networking equipment or AirPort Base Station, and your router from their power outlet. Wait 30 seconds, then plug everything back in.
Cheers,

If you have attempted the reset, which is holding the home button and sleep/wake button, was it still connected to the computer? Have you tried to do that when not connected. You stated it never came on, how long did you hold the buttons together? If you cannot get it to connect to iTunes then you would not be able to restore the device. You can see if you can put the device into Recovery Mode by following the instructions in this support document. If that does not work, then you are correct, make an appointment at the Apple Store. If you can't update or restore your iOS device

TS1717 I downloaded a latin jazz album but on one tune it quit after about 40 seconds and jumped to the next tune.I tried to re download it but that particular tune was only available as an album purchase which I had already done.

I recently downloaded a CD but one tune quit after about 40 seconds.I tried to download again even if I paid again but this track was not available as a single download only as a complete album and I wasn,t prepared to buy the whole album again since I,d already paid for it.Any sugestions?MAC PHILLIPS

Assuming you are in a region where you are allowed to redownload your past music purchases, delete the problem tracks from your iTunes library, close and then reopen iTunes, go to the iTunes Store home page, click the Purchased link from the Quick Links section in the right-hand column, then select Music and Not on this computer. You should find download links for your tracks there.
While downloading select Downloads in the left-hand column and make sure Allow Simultaneous Downloads is unticked.
If the problem persists, or that facility is not yet available in your region, contact the iTunes Store support staff through the "Report a problem" links in your account history, or via Contact Support.

Video and audio (in one direction only) deteriorate after about 90 seconds

I begin a two-way video chat as normal, both parties can see and hear clearly. After about one and a half minutes of normal video chat, the person on the other end suddenly starts getting a highly pixelated image of me, and they start to lose chunks of audio from me. Meanwhile I continue to get a very nice clear video and audio from them. We usually end up closing the chat, because they are unable to hear or see me enough to continue.
The first 1.5 minutes or so is always clear, it starts after that. I always receive good audio and sound from the other party throughout the chat. I have never had problems receiving video/audio.
It happens with most (but not all) people I connect to. I am in California, and I always have this trouble when connecting to a relative in Connecticut. I have the problem again with one relative in Sydney Australia, but not with a different relative in Sydney. These are just a few examples by location.
I have repeatedly tested my connection speeds, and I have good up and down speeds - more than the minimum requirements. (My speed today is 8200 kb/s Down, 1309 kb/s up).
I have also tried:
Checking my Quicktime settings - (set to 1.5 Mbps T1/Intranet/LAN)
Bypassing my Airport modem/router, by connecting directly by ethernet to my Comcast cable modem (which has no router built in)
Replaced the cable modem with a brand new one.
Changed locations - tried it at a friend's house, still had the same problem.
So, I think I have isolated the problem to my PowerBook. This PowerBook used to do iChats really well for at least 18 months. I have been having this issue for about 5 or 6 months now. I have no idea what the problem could be. Any tips would be much appreciated.
Thanks, Martin
My setup:
ISP: Comcast Cable (Cable modem)
Apple Airport Exteme Base Station
Powerbook G4 1.67Ghz, 1 GB RAM, 80 GB HD
O/S: Tiger 10.4.10
iChat 3.1.8 (with Chax)
External iSight camera

With Comcast.
Try rebooting the Modem.
This seems to refresh the connection in some manner.
Also speak to them. They may not admit any connection management but thing may "magically" get better.

I don't know if you've got this solved or not but I started getting this too about a month ago. I just had it happen again about 10 minutes ago. I was on a website & BAM black screen, I don't hear the usual "winding down" of the hard drive though, so the HD sounds as though it's still working properly AND there's a weird hue around the edges of the screen so it's not pitch black as though the monitor turned off. Once I force shut down then I get the true pitch black screen before it turns back on again.
Also, every time this happens & I re-start the hard drive tends to be working very hard doing something in the background for at least 2-5 minutes not sure why?

Firefox4 freezes on startup after about 10 seconds. A second parallel instance of firefox works normally as long as the first instance is left alone frozen. What causes this and how can it be prevented?

I am running firefox4 on win XP. When I start firefox, it says it is trying to restore a previous session which has only the blank tab. After about 10 seconds the whole instance of firefox freezes - none of the buttons work and the only way to close firefox is to use the Ctrl+Alt+Del and task manager. If I open a second parallel sessionof firefox, it works normally, as long as the first session is left alone (frozen). What could be causing the freeze up of the first firefox instance, and how can it be prevented?

I've done some research on the SQLite database. Whenever Aperture hangs up (like during auto-stack or opening the filter hud) there are thousands of SQLite queries happening. These SQLite queries cause massive file I/O because the database is stored on the disk as 1kb pages. However, the OS is caching the database file; mine's only 12MB. I'm trying to track down some performance numbers for SQLite on osx but having trouble.
It's starting to look like most of the speed problems are in the libraries that Aperture uses instead of the actual Aperture code. Of course, that doesn't completely let the developers off the hook since they choose to use them in the first place.
Oh, and if anyone is curious, the database is completely open to queries using the command line sqlite3 tool. Here's the language reference http://www.sqlite.org/lang.html
Hmm, just found this. Looks like someone else has been playing around in the db http://www.majid.info/mylos/stories/2005/12/01/apertureInternals.html

Has Apple acknowledged the problem yet with itunes aborting preview of songs after about 10 seconds on windows 7 and if so is there an answer other than ipconfig?

Has Apple acknowledged the problem yet with itunes aborting preview of songs after about 10 seconds on windows 7 and if so is there an answer other than ipconfig? IPConfig /flushdns doesn't help at all. Until they fix it I will be previewing and buying my songs thru Amazon.

Doublechecking ... do you still get that if you update to iTunes 10.6.3.25 (just released today)?

Assuming you are in a region where you are allowed to redownload your past music purchases, delete the broken files from your iTunes library, go to the iTunes Store home page, click on the Purchased link from the Quick Links section in the right-hand column, then select Music and Not on this computer. You should find download links for your tracks there.
If you don't see them straight away it may help to close and restart iTunes.

If yo mean the iPod will not connect to your wifi network:
Does the iPod connect to other networks?
Do other devices now connect?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do? How can I get the data off this disc? I can see it has been already burned, so files are on there?

Try cleaning the lens and see if that will restore functionality to the DVD drive. Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth) around a business card and insert it gently inside the slot.
If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.
Ciao.
