SAFETY PRECAUTIONS

Four types of messages are used in this manual to bring important information to your attention. Each of these messages will be italicized and identified as shown below:

  • DANGER: “Danger” indicates the existence of a hazard that could result in death or serious injury if the safety instruction is not observed.

Improper repair of the computer may result in safety hazards. Toshiba requires service technicians and authorized dealers or service providers to ensure the following safety precautions are adhered to strictly:

  • Be sure to fasten screws securely with the right screwdriver. If a screw is not fully fastened, it could loosen and create a short circuit, which could cause overheating, smoke, or fire.
  • If you replace the battery pack, RTC battery, or backup 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.
