About this task

CAUTION This computer is designed without an RTC coin cell-battery. After a service incident where the system battery is disconnected, when the battery is fully discharged, or when the system is reassembled and turned on, an RTC reset cycle will occur. When an RTC Reset cycle occurs, the system 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 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.
