undertightening can result in electrical shorts or other damage if screws or
components come loose.
NOTE: Toshiba recommends that you use an electric screw driver for quick and
easy operations.

NOTE: The computer contains several flat head screws. These screws have less
contact area with the screwdriver, so be careful to press firmly enough to prevent
the screwdriver from slipping out and damaging the screw head.
