Chapter 2: Getting Started

Main And Backup Batteries

If you are going to use more than one battery pack, you should indicate this on the Battery tab of the Power Properties dialogue by selecting the check-box ‘Using mul- tiple main battery packs’. This option indicates that any time you remove a battery, you may be replacing it with a different one. When the battery is removed, the NETBOOK PRO discards the current battery capacity information, and starts from the ‘Not calibrated’ state for the battery gauge.

Important: Always switch off the NETBOOK PRO before removing the main battery.

2.5.1.4The Internal Backup Battery

The NETBOOK PRO has an internal backup battery designed to retain data while the main battery pack is being changed over and the unit is not connected to external power. The backup battery is a pair of non-rechargeable alkaline AAA cells that may be changed by the user.

Important: If both the main battery pack and the backup battery are allowed to fully discharge, you will lose all your information in internal memory. However, some of your data can be protected from loss using the flash folder. Please refer to page 65 for details.

The backup battery is user-replaceable. To replace it:

1.Switch the NETBOOK PRO off.

2.Position the display at a slight angle forward to access the backup- battery cover, which is located on the left above the computer keyboard (see Figure 2.8 on page 19).

3.Apply downward pressure to the center of the backup-battery cover and slide it towards the front of the NETBOOK PRO.

4.Remove the AAA cells.

5.Insert replacement alkaline AAA cells, observing the polarity indication.

6.To close the compartment, slide the cover back over the batteries while again applying downward pressure to the center of the cover.
