Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite L300/L305 / Satellite Pro L300 / EQUIUM L300 /
SATEGO L300, referred to as Satellite L300/L305 / Satellite Pro L300 / EQUIUM L300 /
SATEGO L300 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, 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.
