When you add a hyperlink to a presentation, you must be careful that the target of the hyperlink is available. If you are giving the presentation offsite using a laptop, all the targets need to be on the laptop as well, unless your laptop is actively connected to the Internet.

An alternative is to copy Web site documents you think you will need to your laptop and hyperlink to those documents.

The advantage is that you don't have to depend on getting a good connection to the Internet at your offsite location.
