the problem you may met

An Apple store employee told us that each Apple mobile device battery should be depleted to 0% once per month to keep its battery healthy. Is this necessary?

A:

That’s correct. Here’s part of the company’s advice on iPhone batteries: “For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).”

In its advice on laptop batteries, the company states, in part: “Apple does not recommend leaving your portable plugged in all the time.” It adds that, if you don’t drain and recharge your Mac laptop in the course of normal usage, “Apple recommends charging and discharging its battery at least once per month.”

I have been warned on the Web that Microsoft Office won’t work on Apple’s new Mac operating system, Lion. Is this true?

A:

In my tests, and also according to Microsoft, Office for the Mac does work in Lion, though some relatively minor features won’t work right. Also, you must be using one of the two latest versions of Office.

In my tests, using the current version, Office 2011, all features I tested worked fine, though of course I wasn’t able to test every one of the thousands of features. I even wrote my entire Lion review in Word 2011 on a Lion-equipped Mac. According to Microsoft, the 2008 version also works, though the 2004 version doesn’t.

However, Microsoft hasn’t updated Office for Mac to take advantage of Lion’s new features. More information on Mac Office compatibility with Lion is at http://bit.ly/pf1zk5and http://bit.ly/nioLbT.
