Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer Satellite M200/M205 / Satellite Pro M200, referred to as
Satellite M200/M205 / Satellite Pro M200 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.

Off-State Charge
On-State Charge
3/6/9 Cell About 4 hours max
3/6/9 Cell About 4~10 hours max
NOTE: The time required for normal charge depends on the power consumption by the
system. Using the fluorescent lamp and frequently accessing the disk consume much
power and lengthen the charge time.
Any of the following cases stops battery charge:
1. The battery becomes fully charged.
2. The AC adapter or battery pack is removed.
3. The battery or AC adapter voltage is abnormal.
Detection of full charge
A full charge is detected only when the battery is being charged by quick or normal
charge. A full charge is detected when either of the following conditions is met:
1. The current in the battery charging circuit drops below the predetermined
value.
2. The charging time exceeds the fixed limit.
1.1.3 RTC Battery
The RTC battery provides power to keep the current date, time and other system
information in memory while the computer is turned off.
