To remove the base cover, turn the computer over and loosen the eight captive screws that secure the base cover to the palm-rest assembly.
Using the flat-end of a plastic scribe, pry the base cover from the U-shaped indent at the top edge of the base cover and continue to work on the sides to release the base cover from the palm-rest assembly.
Lift and remove the base cover off the palm-rest assembly. Disconnect the battery cable from the connector on the system board. Turn the computer over and open the display.
Press and hold the power button for fifteen seconds to ground the computer and drain the flea power. After draining the flea power, close the display, and turn the computer over.
