Preface
This maintenance manual describes how to perform hardware service maintenance for the
Toshiba Personal Computer TECRA M10
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.

1.9.1 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.
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 1-10 lists the charging time required for
charges.
Table 1-10 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
Extended Capacity battery (7,050 mAh) About 5.0 to 19.5 About 3.5
High capacity battery(7,200 mAh) About 6.0 to 21.0 About 4.0
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.
When turning off the power in being charged fully, the preservation time is as
following Table 1-11.

1.9.3 RTC battery
The RTC battery provides power to keep the current date, time and other setup information
in memory while the computer is turned off. Table 1-12 lists the charging time and data
preservation period of the RTC battery.

Chapter 2 describes how to determine which Field Replaceable Unit (FRU) in the computer is
causing the computer to malfunction. (The “FRU” means the replaceable unit in the field.)
The FRUs covered are:
1. Power supply 8. Optical Disk Drive 15. PCI ExpressCard slot
2. System Board 9. Modem 16. Fingerprint Sensor
3. USB FDD 10. LAN 17. Web camerta
4. 2.5” HDD 11. Wireless LAN 18. Intel Turbo Memory
5. Keyboard 12. Bluetooth
6. Touch pad 13. Sound
7. Display 14. Bridge Media slot
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:
Use the flowchart in Figure 2-1 as a guide for determining which troubleshooting procedures
to execute. Before going through the flowchart steps, verify the following:
Ask him or her to enter the password if a password is registered.
Verify with the customer that Toshiba Windows is installed on the hard disk. Non-
Windows operating systems can cause the computer to malfunction.
Make sure all optional equipment is removed from the computer.
If the diagnostics program cannot detect an error, the problem may be intermittent. The Test
program should be executed several times to isolate the problem. Check the Log Utilities
function to confirm which diagnostic test detected an error(s), then perform the appropriate
troubleshooting procedures as follows:
1. If an error is detected on the system test, memory test, display test, CD-ROM/DVD-
ROM test, expansion test, real timer test, sound test or Modem/LAN/Bluetooth
/IEEE1394 test, perform the System Board Troubleshooting Procedures in Section 2.4.
2. If an error is detected on the floppy disk test, perform the USB FDD Troubleshooting
Procedures in Section 2.5.
3. If an error is detected on the hard disk test, perform the HDD Troubleshooting
Procedures in Section 2.6.
4. If an error is found on the keyboard test (DIAGNOSTICS TEST) and pressed key
display test (ONLY ONE TEST), perform the Keyboard Troubleshooting Procedures
in Section 2.7.
5. If an error is found on the touch pad test (ONLY ONE TEST), perform the touch pad
Troubleshooting Procedures in Section 2.8.
6. If an error is detected on the display test, perform the Display Troubleshooting
Procedures in Section 2.9.
7. If an error is detected on the CD-ROM/DVD-ROM test, perform the Optical Disk
Drive Troubleshooting Procedures in Section 2.10.
8. If an error is detected on the modem test, perform the Modem Troubleshooting
Procedures in Section 2.11.
9. If an error is detected on the LAN test, perform the LAN Troubleshooting Procedures
in Section 2.12.
10. If an error is detected on the wireless LAN test, perform the Wireless LAN
Troubleshooting Procedures in Section 2.13.
11. If an error is detected on the Bluetooth test, perform the Bluetooth Troubleshooting
Procedures in Section 2.14.
12. If an error is detected on the sound test, perform the Sound Troubleshooting
Procedures in Section 2.15.
13. If an error is detected on the sound test, perform the Bridge Media Troubleshooting
Procedures in Section 2.16.
