I own an old PowerBook G3 that turns o only on battery. And, even so, always resets time and date. Whenever I connect the power cable, it turns off. In addition, I a interested in refurbishing my old G3. And, a lesser old G4 LCD that shows a yellow vertical hair-width stripe.
Thank you in advance.

What model PowerBook? The internal PRAM battery has discharged and is not recharging. You'll need to replace the battery. This site has instructions. http://www.ifixit.com/Browse/PowerBook
The PRAM battery is not easy to change on some PB G3 models. I changed the battery on a Wallstreet model. Had to totally disassemble to do it. Bought the replacement battery on eBay.

HT201269 I have an IPhone 4 that turns off.When I plug the phone into a outlet, it says to connect to iTunes. But my phone doesn't connect. I need to backup info to sync to a new iPhone. Is there another way to get the info from the old one?

I have an IPhone 4 that turns off on its own. When I plug the phone into an outlet, it says to connect to iTunes. When i connect my phone to itunes, the screen displays the apple icon and doesn't connect to iTunes. I need to backup info on this phone so I can apply my back up to a new iPhone. Is there any another way i can do this? My older phone will not show it's connected to iTunes. I used iCloud on the phone with problems, but I didn't back up all the info thru iCloud. Is there another way to back up?

Sounds like your phone is in recovery mode. In this case, all data on it is gone. There's nothing to back up.

3-wk old iPad won't turn off. Has words on the screen that say "iCloud Backup, This iPad hasn't been backed up in 3 weeks. Backups happen when this iPad is plugged in, locked and connected to Wi-Fi." The message has OK below it but won't disappear. HELP!

I've gotten 60 or 70 messages that that my iCloud doesn't work and to select preferences. The message says I will get an email to verify but I never get an email. I've checked old email, blocked email, and have low filters on emails. Any ideas?

Hey CarolinQc,
Thanks for the question. The symptoms you are experiencing can result from an Apple ID address that has been changed prior to signing out of all of the services. Before you change the email address associated with your Apple ID, you’ll want to sign out of all services to avoid this. As a fix, you can temporarily change your Apple ID back to the old address:
iOS 7: If you're asked for the password to your previous Apple ID when signing out of iCloud
http://support.apple.com/kb/TS5223
Change your Apple ID temporarily
If signing out and back in to iMessage or FaceTime didn't help, try these steps:
1. Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
2. Go to Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:
          - Scroll down and tap Delete Account, then tap Delete to confirm.
          - Tap “Keep on My [Device]” or “Delete from My [Device].” In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
          - Enter the password for your previous Apple ID.
3. Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.
4. Return to Settings > iCloud and sign in with your new Apple ID.

My one day old MacBook pro just turned off and it won't come back on either through mains or battery power

My one day old MacBook pro just turned off and it won't come back on either through mains or battery power it's as if the unit is completely dead. Even with the mains plugged in there is no green or orange light to say its charging or full charged. The battery was fully charged anyway seconds before the screen went off.

When you say no green or orange light are you refering to the little led on the magsafe connector? That could mean either the charger/cable are bad or the circuitry in the MBP is faulty. Since this is a brand new MBP best bet is to take it back to an Apple Retail store and have the genius bar staff take a look. They can determine if it needs to be reparired or replaced.

HT4061 My phone will not turn on. I did a hard reset but all that my screen will show is a picture indicating I should connect the power cord to iTunes (iTunes icon).I don't know my serial # and I do not have acces to my laptop

My phone will not turn on. I did a hard reset but all that my screen will show is a picture indicating I should connect the power cord to iTunes (power cord symbol with an arrow iTunes icon).I don't know my serial # and I do not have acces to my laptop.

The serial number has nothing to do with this.
YOur phone is in recovery mode.
You will need access to a computer with itunes on it to restore your phone.

How do I get old purchused songs that were deleated from my account and my liberary?

How do I get old purchused songs that were deleated from my account and my liberary?

It has always been very basic to always maintain a backup copy of your computer for just such an occasion.
Use your backup copy to put everything back.
You buy one and only one download. It is your responsibility to move/copy/backup your music.

HT203167 I have lost my audiobooks that I purchases on my old phone. I have gotten a new phone and they are not in the iTunes downloads. Please help.

I have lost my audiobooks that I purchases on my old phone. I have gotten a new phone and they are not in the iTunes downloads. Please help.

Audiobooks are currently a one-time only download - have you not got them on your computer and/or on a backup ? If not then you can try contacting Apple, but they are under no obligation to let you re-download them : http://www.apple.com/support/itunes/contact/

HI there all, have got a 2 year old macbook pro that just recently wont start up. Even if I know the battery is fully charged. What I have to do is remove the battery, wait a minute or so, insert back in and it will fire up. Any ideas?

Try the old two stand-by's first:
Reset PRAM, and;
Reset SMC.
If that doesn't help, call back,

For music that you've purchased from Apple that are on your iPhone you should be able to copy to your computer's iTunes via File > Transfer Purchases. Also if you are in the US then you should be able to re-download past music purchases for free : http://support.apple.com/kb/HT2519
For your own music that you've copied, then if you haven't got a backup on, for example, external drives or CDs/DVDs then you could see if any of the utilities mentioned in this old post still exist and work

After updating my time and date is stuck on the time it was updated and the current time is overlapping that. How do I fix this??

Restore iphone 4 to install the ios 5 but something went wrong while doing back up and whenever i connect the phone to itunes theres an error and the phone turn off after 1min

hi guys i just downloaded the ios 5 and while it was doing back up something went wrong and everything were stopped and shows me a message as an error msg and now whenever i connect my iphone 4(32g) to itunes after 1min it goes off and the battery full and the same thing happend again and again can u help me guys plz i only see connect to itunes on the screen no options even

by reset option do you mean the DFU restore? worked for me, have you tried that?
if not - hold the lock and home button until the power down bar comes up. then hold the lock button for ten seconds - next continue to hold the lock button and press the home button for ten seconds - next release the lock button and hold the home button for 10 seconds. this should be done with the phone tethered. If done right and your itunes is configured as such, the phone will reload the drivers and start up itunes, and then prompt for a restore/update.

I own an old PowerBook G3 that turns o only on battery. And, even so, always resets time and date. Whenever I connect the power cable, it turns off.
