About this task

NOTE: For computers shipped with 10th Generation Intel Core i5-10400F and 10th Generation Intel Core i7-10700F processors a VGA-connector cover is installed over the VGA connector and needs to be removed when the VGA-connector board is removed.
NOTE:Your computer's Service Tag is stored in the system board. You must enter the Service Tag in the BIOS setup program after you replace the system board.
NOTE:Replacing the system board removes any changes you have made to the BIOS using the BIOS setup program. You must make the appropriate changes again after you replace the system board.
NOTE:Before disconnecting the cables from the system board, note the location of the connectors so that you can reconnect the cables correctly after you replace the system board.
