How Do I Check the Battery Level?
To check the battery level, tap Start > Settings > System tab > 
Power > Main tab. You can view the amount of battery power 
remaining for both the main battery and the backup battery.
If the battery charge level is low, connect to AC power using 
the desktop cradle or the sync cable, or change the battery. For 
information on purchasing a spare battery or Extended Battery, 
visit the HP Web site at

CAUTION: It is recommended that you not allow the battery 
installed in your HP iPAQ to discharge completely. Doing so will not 
harm your HP iPAQ or battery, but you lose all data that is not stored 
in main memory. Discharging the battery completely is similar to 
performing a hard reset. Refer to 
Default Settings and Erase All My Data (Perform a Hard “Full” 
Reset)?”
