HDX16T LCD Screen flashes then blacks out, quick to sleep and out brings it back...

I have an HP HDX16T-1200 CTO with the 1080 edgeless disply. All of a sudden the screen has been doing weird things. While it is working fine, it will start to flicker or flash a little. Sometimes that just goes away, and sometimes the screen then blacks out. To get the screen back, I have to close the lid (put the computer in sleep mode), then open it again. Sometimes it is fixed for hours, or a day... and sometimes it is fixed for 3 minutes. Please advise, thanks!

If you can clean and/or put new thermal paste on the chip itself that may fix the problem. If you search the web for "*ERROR* Timeout setting UVD clocks!" you'll find many threads on Bugzilla about this issue. It seems that this is a long-standing issue (dating back to 2013 I believe).
So are you saying the GPU is overheating? This is the card I am using: http://www.newegg.com/Product/Product.a … 6814150605 I have it hooked up to my motherboard on my desktop. Would this be related to something switching between the motherboard graphics and this card?

I recently dropped my ipod in water and i placed it into rice for 3 days. Then when i try and connect it to the computer it shows the no battery screen with just the lightning bolt. and when i try to restore it the screen flashes then resest

Then when i try and connect it to the computer it shows the no battery screen with just the lightning bolt. and when i try to restore it the screen flashes then resest to the no battery screen and i get error 1602. Do you know what is wrong with it? do you think its just the battery cause i can replace that for cheap or do you think the circuts are fried?

No. It sounds like the water destroyed the component inside the iPod.
About your only choice now it to take it to Apple and pay for a replacement.

Why does my iphone 3gs screen goes black after reaching another party and won't come back on to press end the call

why does my iphone 3gs screen goes black after reaching another party and won't come back on to end the call

hi smalley3,
Welcome to the Forums.
The flickering issue maybe due to a bad LCD cable or in some cases, a faulty GPU (the GPU is integrated to the CPU, and the CPU is soldered to the motherboard).
If there's still no image on the screen even after connecting an external display then you likely have a bad GPU.
In this case, I recommend you contact support for service (and also to see if there's a consideration that can be done on the warranty repair).

Is your battery out of juice, have you tried charging it? If the battery is flat dead it may take a few minutes after plugging it in before the screen will show anything.

Is it possible to use Siri to send text messages to groups? I want to be able to say to Siri "Send a text message to the people in 'group 4' category." I then dictate the text message, confirm, and out it goes. Groups of 100 to 250 contacts.

Thanks in advance for your help.

Hmmm, that's strange - just checked again and it is 1066288.

It's telling you to verify your billing information (credit card, address, security code), which needs to be done in iTunes via computer.

Restore as new in itunes and try again.

I bought a movie three days ago. It begins to download from the cloud, then my iPad goes to sleep and when I open it again, it starts downloading from the BEGINNING. How do I get the WHOLE MOVIE to download? I have re-booted but that didn't help.

I can't seem to figure out how to download a movie. It begins to download (and yes, I've checked my download speed and my bandwidth and both should, in theory, be adequate to download a movie!) but then the iPad will go to sleep and when I get back to it, it shows that I have bought the movie but nothing is downloaded. And when I try to download the next time, nothing is saved and it starts again from the beginning of the download.
I sat down by my iPad while I was working and every few minutes I would swipe to turn it on and it got over half of the movie downloaded. But then I had to go to leave and now it shows nothing is downloaded.
I can see having it take a few hours to download IF one was able to just start the download and walk away and come back later to watch the movie. But to have to repeatedly begin from the start of the download is incredibly frustrating. I would want my money refunded to my iTunes account at this point, if I was able to do that. It's just not worth the hassle.
Suggestions? How does one download a movie from iTunes? It should not have to be this hard!!

See if you can redownload it.
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If you can then delete from your iPod if you can and redownload.
If you can't delete from iPod, go to to iTunes>Store>Check for Available Downloads on your computer , amd dpwnload and sync

TS3274 my ipad has a agreement plan on it amd will not let me out of it ot says agree or doagree and i chopse eitjer and it doesnt do anything i turn it off and it nrings me to hello and slide i do and it brings me back to the agreement it says email i pr

Hi jacks,
First close out all open apps: Click the Home key twice, and then swipe up on each of the thumbnails showing above the open app icons until all of them are swiped off
Then go to Settings>Safari and under the Privacy & Security section make sure the "Block Cookies" option is either set to "From Third Parties" or "Never".
Then try to do the agreement again.
Cheers,

I've been using my cell phone number to imessage from my ipad for a while now, but yesterday I got signed out of I message and when I signed back in, I didn't get the option to use my number, only my email adress. How can I fix that?

Hey bill.rizzo2,
Thanks for the question. I understand your phone number is missing on your iPad as an option for iMessage. The following article provides steps to resolve this issue:
iOS and OS X: Link your phone number and Apple ID for use with FaceTime and iMessage
http://support.apple.com/kb/HT5538
Phone number missing on iPad or iPod touch
If your phone number isn't listed on an iPod touch or iPad, follow these steps:
1. Update to the latest version of iOS.
2. Verify that you're using the same Apple ID that you're using on your iPhone.
3. On your iPad or iPod touch, sign out of your Apple ID in the following locations:
    - Settings > Messages > Send & Receive. Tap your Apple ID, then tap Sign Out.
    - Settings > FaceTime. Tap your Apple ID, then tap Sign Out.
4. Sign in to your Apple ID with FaceTime and iMessage.
If your phone number still isn't listed, follow these steps:
1. Sign out of your Apple ID on all iOS devices, including your iPhone, in the following locations:
    - Settings > Messages > Send & Receive. Tap your Apple ID, then tap Sign Out.
    - Settings > FaceTime. Tap your Apple ID, then tap Sign Out.
2. Sign in to your Apple ID on your iPhone.
3. When activation is complete, your Apple ID and all verified email addresses should be visible in Settings > Messages > Receive At and Settings > FaceTime.
4. Sign in to your Apple ID on your other iOS devices.
Thanks,
Matt M.

Screen goes to sleep and won't come back on - how to fix?

My 2009 MacBook screen goes to sleep and won't come back on. It just stays black while the computer is still running. This just started happening one day for no apparent reason. Anyway to reconcile?

When you post for help, please state which OS X is installed.
If you aren't sure, click About this Mac from your Apple menu 
Troubleshooting advice can depend on that information.

Todays update! After todays update I can no longer send Safari or Spotify to the task bar without it cutting out (dropping audio in and out). Streams normally if I keep the window open on my desktop. This needs to be fixed immediately.

Nevermind. I figured it out.

I keep getting an error when trying to update an app- cannot connect to store. I logged out from my account and tried to log back in and got the same error. I am doing all this from my phone since I no longer own a personal computer (only work)

YAY!!! Saved it in my Mac's Firefox Bookmarks for easy future access!
Hope you are having a lovely afternoon today! I'm about ready to go bobo....I have an early meeting, and I don't want to oversleep! The nice part is that I work remotely, so I only have to wake up 15 minutes or so before the meeting.... I don't even use an alarm clock anymore (really, my iPhone alarm, which is much more pleasant), unless I have to get up at 6:30 or something....

Updating Snow Leopard won't help. You need to Upgrade OS X to Lion or higher if your system will support it. First check to see if your system meets the system requirements to upgrade.
Lion system requirements are:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Mountain Lion and Mavericks requirements are the same, and are shown here: http://support.apple.com/kb/HT5842.
If you can run Mavericks, you can download a free upgrade from the Mac App Store. If your system can only run Lion, or you need Mountain Lion rather than Mavericks for software compatibility reasons, youcan contact the online store at the number shown at the bottom of this page and purchase a redemption code to download it from the Mac App Store.
After upgrading, you will find iCloud in System Preferences>iCloud on your Mac, and can set it up as explained here: http://www.apple.com/icloud/setup/mac.html.
Before upgrading, you should be aware that PPC programs such as AppleWorks will not run on Lion or above. You may want to check the compatibility of your existing programs by checking here: http://roaringapps.com/apps:table.

HT1222 I started the lastest iPhone 5s software update then my phone just shut down and will not turn back on. I've tried the home button, the button plus the top right button together for 20 sec, plug it in and nothing

Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.
