Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite, referred to as the Satellite Series in this manual.
The procedures described in this manual are intended to help service technicians isolate faulty
Field Replaceable Units (FRUs) and replace them in the field.
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 bodily injury if the safety instruction is not observed.
WARNING: “Warning” indicates the existence of a hazard that could result in bodily
injury if the safety instruction is not observed.
CAUTION: “Caution” indicates the existence of a hazard that could result in property
damage if the safety instruction is not observed.
NOTE: “Note” contains general information that relates to your safe maintenance
service.
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 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.
