How to Disconnect from Your Dial-up Account after Checking E-mail
When you’re using a dial-up account from your laptop, keep in mind that you don’t need to be connected to the Internet while you read your e-mail. Especially given how much power the modem draws, you should have your e-mail program immediately hang up (or disconnect) after sending or receiving e-mail. Here’s where to check those settings in Microsoft Mail and Outlook Express:
The Options dialog box duly appears.
Click the Connection tab in the Options dialog box.
Select the Hang Up After Sending and Receiving check box.
Remember that this setting isn’t needed for broadband access.
You may also want to disable automatic checking.
