Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer TECRA R10.
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.

Conventions
This manual uses the following formats to describe, identify, and highlight terms and
operating procedures.
Acronyms
On the first appearance and whenever necessary for clarification acronyms are enclosed in
parentheses following their definition. For example:
Read Only Memory (ROM)
Keys
Keys are used in the text to describe many operations. The key top symbol as it appears on
the keyboard is printed in boldface type.
Key operation
Some operations require you to simultaneously use two or more keys. We identify such
operations by the key top symbols separated by a plus (+) sign. For example, Ctrl + Pause
(Break) means you must hold down Ctrl and at the same time press Pause (Break). If
three keys are used, hold down the first two and at the same time press the third.

1.10.1 Main Battery
The removable main battery pack is the computer’s main power source when the AC adaptor
is not attached. The main battery maintains the state of the computer when the computer
enters in sleep mode.
TECRA R10 Maintenance Manual (960-708) [CONFIDENTIAL] 1-27

1 Hardware Overview 1.10 Batteries
1.10.2 Battery Charging Control
Battery charging is controlled by a power supply microprocessor. The microprocessor
controls whether the charge is on or off and detects a full charge when the AC adaptor and
battery are attached to the computer. The system charges the battery.
Battery Charge
When the AC adaptor is attached, there are two types of charge: When the system is powered
off and when the system is powered on. Table 1-8 lists the charging time required for charges.
Table 1-8 Time required for charges
Battery type Power on (hours) Power off (hours)
Battery(4,000 mAh) About 3.0 to 9.5 About 2.5
Battery(5,100 mAh) About 4.0to 12.0 About 3.0
Slice Expansion battery (4,000 mAh) About 3.0 to 9.5 About 2.5
NOTE: The time required when the system is powered on is affected by the amount of
power the system is consuming. Use of the fluorescent lamp and frequent disk
access diverts power and lengthens the charge time.
If any of the following occurs, the battery charge process stops.
1. The battery becomes fully charged.
2. The AC adaptor or battery is removed.
3. The battery or output voltage is abnormal.

2. System Board 9. Optical Disk Drive 16. Fingerprint Sensor
3. USB FDD 10. LAN 17. Web camerta
4. HDD/SSD 11. Wireless LAN 18. Intel Turbo Memory
5. Keyboard 12. Bluetooth
6. Touch pad 13. Sound
7. Membrane switch 14. 3G
The Test Program operations are described in Chapter 3. Detailed replacement procedures are
described in Chapter 4.
NOTE: Before replacing the system board, it is necessary to execute the subtest 03 DMI
Information save of the 3.4 Setting of the hardware configuration in Chapter 3.
After replacing the system board, it is necessary to execute the subtest 04 DMI
Information recovery and subtest 08 System configuration display of the 3.4
Setting of the hardware configuration in Chapter 3. Also update with the latest
EC/KBC as described in Appendix H “EC/KBC Rewrite Procedures”.
After replacing the LCD, update with the latest EC/KBC as described in Appendix
H “EC/KBC Rewrite Procedures” to set the SVP parameter.
The implement for the Diagnostics procedures is referred to Chapter 3. Also, following
implements are necessary:

2.4 System Board Troubleshooting 2 Troubleshooting Procedures
Procedure 1 Message Check
When the power is turned on, the system performs the Initial Reliability Test (IRT) installed
in the BIOS ROM. The IRT tests each IC on the system board and initializes it.
If an error message is shown on the display, perform Check 1.
If there is no error message, go to Procedure 2.
If MS-DOS or Windows OS is properly loaded, go to Procedure 4.
Check 1 If one of the following error messages is displayed on the screen, press the F1 key
as the message instructs. These errors occur when the system configuration
preserved in the RTC memory (CMOS type memory) is not the same as the actual
configuration or when the data is lost.
If you press the F1 key as the message instructs, the SETUP screen appears to set
the system configuration. If error message (b) appears often when the power is
turned on, replace the RTC battery. If any other error message is displayed,
perform Check 2.
(a) *** Bad HDD type ***
Check system. Then press [F1] key ......
(b) *** Bad RTC battery ***
Check system. Then press [F1] key ......
