New replacement battery worse than old one

My Ibook 12" and battery were on the recall list. I didn't notice to much in the way of heat or bad battery life before the recall, but I thought this was a good chance to get a new battery. Well the new one came and it is way worse than the old one. Fan is running almost constantly, poor battery life, the hard drive side is getting very hot, Charger is running hot. I don't think I want to keep the new battery, any advise.
Thanks in advance

Hi josh and welcome to Apple Discussions.
Firstly, check to see if your new battery is also on the recall list. It has happened…
Secondly, your new battery is subject to Apple's standard 90 day warrantee. If it is defective, irrespective of its recall status, then it should be replaced. Contact your local Applecare and explain, calmly and politely, the problems that you are having and your concerns for your own safety and that of your iBook. An iBook's fan shouldn't run constantly and the charger shouldn't be uncomfortably hot.
You'll do no harm, and might do some good, by doing a PMU reset:
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait at least 5 seconds.
4. Press the Power button to restart the iBook
Good luck,
Adrian

Replacement battery from recall worse than old one

I received my replacement battery, which I assumed would be new, but it is not doing a very good job of keeping a long charge. Whereas my old battery could give me over 3 hours if I optimized my settings, my new one barely gives me 2. Anyone else get a less than desirable battery after the recall?

Ok, have done two deep cycles, and the meter won't get above 3 hours, then drops and fluctuates a lot between 2:30 and 2:40. At the moment it's at 2:34 and 93%.
The original battery got to over 4 hours when charged, and the meter sometimes touched 5 hours.
Cheers Apple. I now have a battery that's (according to the gauge) not so good for a day of portable use. I'd like the old one back, please!

New Battery Worse than Old

Through Best Buy I had Apple replace the battery in my nearly two-year old iPod Mini 4G. I was getting 5 hours before I sent it off. (A year ago I got nearly 8.) I got it back the other day and did a test: 4 hours! Has anyone else had this experience?
Sheldon
P.S.: Why doesn't iTunes start up when I plug in the iPod. I have it set to do that, but it refuses.

I've fully recharged two more times now. I'm getting about 6 hours and 30 minutes under optimal conditions: No backlight, no EQ, no manual track changes, just repetition of a single album.
Can I expect it to get better than that? Is the age of the battery the only thing that determines play time? The guy at Best Buy said it is also determined by the age of the circuitry. Could that be?

New filters of Nokia Creative Studio much worse than old ones

Hi,
I am very dissatisfied with the new filters of the Nokia Creative Studio of my Nokia Lumia 1020.
The old filters where just great and I did not use my professional camera anymore.
The new filters do not improve the quality and look of the pics, the pics look unnatural and cheesy.
How can I get this feedback to the Nokia developers?
Kind Regards Nicola

New hard drive slower than old one

Hello, my Seagate 120GB 5400rpm drive crashed 6 weeks ago and I made use of the warranty to get a replacement (refurbished) drive. I think this drive is no good because I have noticed a marked decrease in performance:
-Upon coming back from sleep mode the screen turns on but it pinwheels for several seconds, showing the time it was when I put it to sleep.
-My battery also lasts considerably less now. The battery is about a year old and had been lasting me up to two hours. It now doesn't last much more than one.
-I also tried to rip a dvd today and had to stop because it was going 5x slower than it had even on this drive when I first got it.
Is there anything else that could be causing me this decreased performance besides a subpar drive?
I have been in touch with Seagate again this weekend and they suggested I send it in for another replacement, which is fine, but is there a way I can copy all of this drive onto my replacement when it gets here? Or should I need to start fresh and reinstall everything on the new one?
Thanks.

You might want to check that you have selected a startup disk as "Macintosh HD" so the OS x knows where to boot from. If there is no selection under startup items in System Preferences then boot up is delayed by a few seconds as OS X would look for a functional startup disk.
Check and see if this works for you in bringing down boot times.

New Macbook Pro slower than old one.

I recently got a new Macbook Pro, unibody, with 2.8 Ghz core 2 duo and 4 GB Ram. I am upgrading from a Macbook Pro with the previous body design, that is 2.5 Ghz core 2 duo and came with 2GB RAM but I upgraded to 4GB myself.
I got the new MBP, migrated some applications and my settings. Now when I start Firefox I sometimes get the spinning beach ball for a few moments before my homepage loads. Also for example, if I have 2 tabs open, with one playing a youtube video in the background and I'm browsing in the other, the video will stutter and I'll get the beach ball for a few moments when I try to go to another page. This happens no matter what browser I try (Firefox, Safari, Camino). And it never happens on my older MBP, it's a little annoying that a system that is 2 years older seems to perform better.
Any ideas or tips?

Apps are permanently tied to the Apple ID used to purchase them. You will have to delete the apps from the phone and re-purchase them using your Apple ID.

Hi Marg42,
Thanks for visiting Apple Support Communities.
First, your husband can create his own Apple ID via the web, computer, or iPad, if he hasn't already:
My Apple ID
https://appleid.apple.com
iTunes: How to set up an Apple ID within iTunes
http://support.apple.com/kb/ht2731
Next, he can sign out of the Apple services that are currently using your Apple ID on your old iPad, and sign in with his own.
This article has instructions for doing so for specific Apple services:
Apple ID: What to do after you change your Apple ID
http://support.apple.com/kb/HT5796
Alternately, he can erase the device and set it up as new using the steps in this article:

I had Premier pro given me by the college I attend and do no use wi fi and do not use cloud. My laptop completely died and will be sent back to Apple for exchange. How can I reinstall Premier Pro on a new Apple computer since the old one is completly dead

I had Premier pro given me by the college I attend and do no use wi fi and do not use cloud. My laptop completely died and will be sent back to Apple for exchange. How can I reinstall Premier Pro on a new Apple computer since the old one is completly dead and could not be unregistered?

Hi,
You have not specified which version of Premiere Pro was given to you. If you don't have the disc (which i suppose you don't have) you will have to download it online.
As far as your registration is concerned, for Premiere Pro CS6 or earlier you will have to reach Adobe chat support for further help: http://helpx.adobe.com/contact.html
For Premiere Pro CC and later, you will not have much problems reactivating it.
Thanks,

I recently created a new apple ID
Bad idea.
Content bought with an Apple ID is forever associated with that Apple ID. Apple will not transfer content from one Apple ID to another and Apple will not merge Apple IDs. Unless you are prepared to forfeit all the previously purchased content and buy it all again with the new Apple ID, you will need to maintain the old ID to update and redownload your content.

I have a new hard drive as my old one crashed. Everything seemed to transfer fine except for my entire iTunes library. It shows all of my old songs, but when I click on one it states "the song could not be used as the original file could not be found

I have a new hard drive as my old one crashed. Everything seemed to transfer fine except for my entire iTunes library. It shows all of my old songs, but when I click on one it states "the song could not be used as the original file could not be found.would you like to locate it".
Either how do I locate it, and I've tried every trick I know, or how do I restore all of my songs from one of two sources. I have my old hard drive backedup on an external drive which should have all of my songs, and I have most of my songs on my old iPhone 3S which I'm using as a backup iPod.

The "missing file" error happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, one of its parent folders, or the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place. In the case of a library moved from one system to another there are also potential permissions issues. See Repair security permissions for iTunes for Windows.
Select a track with an exclamation mark, use Ctrl-I to Get Info, then click No when asked to try to locate the track. (Due to a bug in iTunes 12 you currently have to say No twice!) Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, a folder renamed, or a drive letter has changed, it should be possible to reverse the actions. If the difference between the two paths is an additional Music folder in one path then this is a layout issue. I can explain further if that is the case.
In some cases iTunes may be able to repair itself if you go through the same steps with Get Info but this time click Locate and browse to the lost track. It may then offer to attempt to automatically fix other broken links.
If another application like Windows Media Player has moved/renamed the files then the chances are that subtle differences in naming strategies will make it hard to restore the media to the precise path that iTunes is expecting. In such cases, as long as the missing files can be found somewhere, you should be able to use my FindTracks script to reconnect them to iTunes. See this post for an explanation of how it works.

I have just bought a new iPhone and gave my old one to my Mum. My problem is that even with a new SIM and phone number I seem to be getting her messages as well as mine on my thread. They are also being recorded as both sent and received so she must be paying twice for each SMS sent. Help please

Wipe iPhone/iPad/iPod touch clean
There are a few steps to do:
Switch off iMessage in Settings > Messages
Switch off FaceTime in Settings > FaceTime (iPod touch 4th Generation or later, iPhone 4 or later and iPad 2 or later)
Delete iCloud in Settings > iCloud > Delete Account
Finally Settings > General > Reset > Erase All Content and Settings.
Un-register your device: https://supportprofile.apple.com
Now you can sell/give.
Now, you should get her a new Apple ID to sign in the options above.

HT5625 I want my new iPad mini to use my new Apple ID, not the old one that pops up without seemingly giving me the choice to update the Apple ID user name; as a result I haven't been able to update my APPS for some time.

I want my new iPad mini to use my new Apple ID, not the old one that pops up without seemingly giving me the choice to update the Apple ID user name; as a result I haven't been able to update my APPS for some time. I changed my apple ID when I got a new e mail address a few months ago .

Any apps you have installed from the old AppleID will always be tied to that AppleID. You have no choice but to enter the password for the old AppleID if you want to update apps downloaded using that ID.
The only way to stop being asked for the password for the old AppleID is to remove all apps from the device that were downloaded using that old AppleID.
You'd then need to re-download (and re-purchase) any apps you want to keep using under the new AppleID.
Apps cannot be transferred between AppleIDs.
