About this task
NOTE: This computer is designed without an RTC coin cell-battery. After a service incident where the computer battery is
disconnected, when the battery is fully discharged, or when the computer is reassembled and turned on, an RTC reset cycle will
occur. When an RTC Reset cycle occurs, the computer turns on and off three times. An "Invalid Configuration" error message
is displayed prompting you to enter the BIOS and configure the date and time. The computer starts functioning normally after
setting the date and time.
NOTE: Removing the battery resets the BIOS setup program's settings to default. It is recommended that you note the BIOS
setup program's settings before removing the battery.
The following image(s) indicate the location of the battery and provides a visual representation of the removal procedure.
