Of overcharging and iPods
Q: I recently got a Bose SoundDock and wanted to know whether it was a bad thing to keep the iPod permanently mounted in the dock. The SoundDock continuously charges it. Can that hurt the battery?—Danny Sat
A: In general, you can’t overcharge your iPod. It’s a savvy little piece of gear that understands when enough is enough, even if it’s connected to a power source like the $299 SoundDock ( ) for days on end. Some folks (but not Apple) suggest that undocking the iPod once a month and letting it run on battery power for a while is a good idea. Allegedly, this will “exercise” the battery and lengthen its life span.
I haven’t tested the theory, because, frankly, I don’t have the patience to conduct multiple-year battery trials. But given that even the most devoted homebody is likely to leave the house on at least a monthly basis, it certainly wouldn’t hurt to take your iPod for a walk every so often.
Another battery question I hear frequently is “So, when should I charge my iPod—should I run it all the way down first? Halfway down?” Invariably, my response is “Don’t sweat it.” No matter what you do, the battery will eventually die, and you’ll either replace it or get a new iPod.
Running an iPod all the way down and letting it sit for a week with no juice is unnecessary—the batteries in iPods don’t have a “memory” that you need to reset by running them dry, as did the batteries in some older devices. Nor will the battery become overly stressed if you recharge it at the end of each day, even though you’ve used only a quarter of its charge.
In short, charge your iPod when it’s convenient. If you’re going on a transpacific flight, then by all means find a spare power outlet at the airport and top your iPod off. Or if you’ve listened to it for only a couple of hours and don’t feel like taking it out of your backpack, pocket, or purse, then leave it where it is at the end of the day, enjoy its many gifts tomorrow, and charge it the next time you think of it.
Q: I recently found a program called Disk Cleaner (for PCs) and was wondering if there was something similar for Macs.—Gordon Werb
A: Disk Cleaner is a free, open-source utility that deletes temporary, cache, and cookie files, as well as stray items in the Recycle Bin, from a Windows PC. There are loads of similar utilities for the Mac, but my favorite is Titanium Software’s OnyX ( ; payment requested). It allows you to easily muck with parts of the operating system that are usually accessible only through Terminal. But unlike many tools of this sort, OnyX helps you stay out of trouble while you do so—it clearly explains what its features do and warns of potential problems.
For example, in the Cleaning tab, where it seems that you’ll be spending the bulk of your time, you’ll discover that you can delete a wide variety of cache files, as well as form values and cookies (see “Empty the Cache”). OnyX warns you that deleting these things may mean that you have to reenter user names and passwords when you revisit favorite sites (this could cause trouble if you’ve neglected to make a note of any passwords).
The case of the missing contacts
Q: Nearly all my Apple Address Book contacts are gone. Worse yet, all the addresses in Microsoft Entourage’s Address Book are gone, too. I’m a .Mac member and use Apple’s Backup to back up my hard drive, so I think I can get my contacts back. I just don’t know where to look.—Turner Rouse
A: Launch Backup, select your regular backup plan (this plan must include either your Home folder or Personal Data & Settings), and click on the Restore button. In the Restore window that appears, select a date whose backup is likely to hold all your contacts—for example, if you recall seeing all your contacts on the day before yesterday, find the backup that most closely precedes that date in the Previous Backups column.
Click on it and then follow this path: your user folder /Library/Application Support/AddressBook. Find the file named AddressBook.data. Select the Restore To An Alternate Location option. Put a check mark in the box next to the file name to select it, and then click on Restore Selection. Navigate to the place where you’d like to put the file, and click on Choose.
Once the program is finished, open the Restored Files folder it has created and dig down through its folders until you get to the AddressBook.data file. Go back to your user folder /Library/Application Support/AddressBook and replace that folder’s AddressBook.data file with the one from the Restored Files folder. Launch Address Book, and it should contain all your contacts.
Now, before you move on to Entourage, do this: In Address Book, choose File: Back Up Address Book. This will do exactly what it says—back up your contacts on your Mac. I don’t know what funkiness caused Address Book to lose your contacts, but if it happens again, you can easily get the contacts back by opening Address Book, choosing File: Revert To Address Book Backup, selecting this backup file, and clicking on Open.
As for Entourage, launch it, open its preferences (Entourage: Preferences), and select Sync Services. You should see that the Synchronize Contacts With Address Book And .Mac option is enabled. Microsoft added the option to synchronize contacts between Apple’s Address Book and Entourage 2004’s Address Book in a recent update. It’s a great feature—unless Apple’s Address Book loses its contacts. When that happens, Entourage syncs with the nearly empty list of contacts. Once you restore your contacts to Address Book, Entourage will update its Address Book with those contacts, as long as this option is on.Empty the Cache: OnyX is one of a number of utilities that can clear out cache, Internet history, and log files.
