CAUTION: Handle with care as the underside of the base cover has pins for grounding the audio board. After
removing the base cover, place it in a location where contact can be avoided.
NOTE: The following steps are applicable only if you want to further remove any other component from your computer.
NOTE: Disconnecting the battery cable, removing the battery, or draining the flea power clears the CMOS and resets
the BIOS settings on your computer.
NOTE: After your computer is reassembled and powered on, it prompts for the Real Time Clock (RTC) reset. When
the RTC reset cycle occurs, the computer restarts several times and then an error message is displayed– "Time of
day not set". Enter the BIOS when this error appears and set the date and time on your computer to resume normal
functionality.
4. Disconnect the battery cable from the system board.
5. Turn your computer over and press the power button for 15 seconds to drain the flea power.
