A number or problems can afflict your Toshiba Satellite laptop's keyboard that may result in performance issues that require a complete keyboard replacement. Fortunately, you don't need any prior experience with keyboard hardware or computers in order to remove the Toshiba Satellite laptop's keyboard yourself. You can perform this procedure using only a flathead screwdriver and a Phillips screwdriver. No other devices or tools are required in order to remove the laptop's battery, the keyboard shield, the keyboard cable and the hardware assembly itself.
Power down your Toshiba Satellite laptop. Unplug the power adaptor from the power source.
Remove the Toshiba Satellite laptop's battery. Turn the Satellite over and remove the battery by sliding the battery release mechanism. This release mechanism is near the top of the unit, directly below the horizontal outline of the battery.
Turn the Toshiba Satellite laptop back over. Open up the laptop so the display is upright and you have access to the keyboard.
Remove the keyboard shield. This is the plastic strip that runs horizontally across the computer, directly above the actual keyboard. Use the edge of a flathead screwdriver or similar object to pry under one of the shield's edges to pop it up and out. Take particular care not to damage the shield with the metal of the screwdriver; it will not take much force to remove the shield.
Remove the two to three screws that are under the keyboard shield using a Phillips screwdriver. The number of screws to remove will depend on the exact model of your Toshiba Satellite laptop.
Pull the keyboard up now that it is loose. Do not remove it entirely, but instead pull up on it until you can see the keyboard cable running from the bottom of the keyboard down to the base of the laptop. Lift up on the keyboard socket so that you can slide the cable out.
Pull the keyboard completely out and lay it aside now that the keyboard cable is disconnected.
Replace the keyboard if you have a replacement at the ready. Lift up on the keyboard cable socket and slide the cable back in. Press down on the socket to lock it back into place.
Replace the keyboard shield, then turn the Toshiba Satellite laptop over and replace the screws on its base.
Replace the laptop's battery. This battery need only to be slid back into the space vacated by the battery previously and pressed firmly enough into the slot so that it snaps back in without wavering or appearing to be loose.
