Just an FYI - a Chromebook DOES work when not online.
You won't be able to do things on the Internet (browse sites, SEND email, etc.), but there is some basic functionality available.
Before "unplugging" from the internet you will need to turn on the "offline" mode on the Chromebook you want to use offline.
You will find the "Offline" option in the settings of many Google Apps.
As an example, lets look at the Gmail Offline App:
- WHILE ONLINE - open your Gmail account
- Click the gear in the upper-right corner
- Choose Settings
- Select the Offline tab (toward the right)
- Click the Install Gmail Offline link
- Follow the prompts to install the app
Other Google apps have similar tools and options. For each, look for "Offline" in the Settings.
For help with any Google App use the icon in the upper right corner.
