Improper repair of the computer may result in safety hazards. Toshiba requires service

? Be sure to fasten screws securely with the right screwdriver. Be sure to use the PH
Point size “0” and “1” screwdrivers complying with the ISO/DIS 8764-1:1996. If a
screw is not fully fastened, it could come loose, creating a danger of a short circuit,
which could cause overheating, smoke or fire.
? If you replace the battery pack or RTC battery, be sure to use only the same model
battery or an equivalent battery recommended by Toshiba. Installation of the wrong
battery can cause the battery to explode.
