Low Backup Battery
When the backup battery becomes low, the backup battery icon appears in the taskbar.
Icon Meaning
Backup battery is low.
Backup battery is very low.
Note that when the charge level in the battery pack gets very low, an exclamation mark (!) appears beside the battery icon. The Aero 2100 will also display a message to alert you. The message recurs periodically until you have replaced the backup battery.
When you see this message, obtain a new backup battery (CR2032) at your earliest convenience from your authorized Compaq Reseller. In the interim period, be sure to make a full backup of the data held in your Compaq Aero 2100 Series, and take steps to make sure that you avoid fully discharging the main battery pack.
