Default Critical and Low Battery Points

Dolphin terminals are programmed to display warnings when the battery reaches critical and low battery points. The following registry entry sets both warning points:

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power]

There are two DWORD values in this registry entry: LowBatt and CriticalBatt. The default values for these entries are as follows:

LowBatt=19 (25%)

This sets the Low Battery point to 25% (19 hex=25 decimal). When the battery hits the

percentage charge specified here, the user is notified by this icon in the Navigation bar .

If the main battery is low and the terminal is in suspend mode, pressing the SCAN or Power button won’t wake the Dolphin terminal; you must replace the discharged battery with a battery charged over 25% mark before you can resume terminal operation.

CriticalBatt=a (10%)

This sets the Critical Battery point to 10% (a hex= 0 decimal). When the battery hits the

percentage charge specified here, the user is notified by this icon in the Navigation bar .

Note: Warnings do not appear when the terminal is on external power.

Setting Critical and Low Battery Points

Developers can re-reset the default battery points in the RegEdit Power Tool.

1.Tap Start > Power Tools > RegEdit.

2.Drill-down to HKEY_LOCAL_MACHINE > System > CurrentControlSet > Control > Power. The CriticalBatt and LowBatt values appear in the list.

3.Tap the Value Name to change the Value Data. You can reset the Value Data from 0 (no warning) to 99 (would warn whenever the charge drops below 99%).

4.Tap OK to save changes.
