About this task

CAUTION:

Before removing the base cover, ensure that there is no micro-SD card installed in the micro-SD card

slot on your computer.

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 base cover and provides a visual representation of the removal procedure.
