About this task
CAUTION This computer is designed without an RTC coin cell-battery. After the battery is disconnected or when the battery is fully discharged, an RTC reset cycle will occur when you restart the computer. 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.
CAUTION Disconnecting the battery cable resets the BIOS setup program’s settings to default. It is recommended that you note the BIOS setup program’s settings before removing/disconnecting the battery.
The following image indicates the location of the battery and provides a visual representation of the removal procedure.
