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. User input Text that you are instructed to type in is shown in the boldface type below: DISKCOPY A: B: The display Text generated by the XXXXX that appears on its display is presented in the type face below:

1.1 Features

The Toshiba Satellite L350D/Satellite Pro L350D/EQUIUM L350D/SATEGO L350D is a full size notebook PC based on the mobile AMD Turion64 X2 and Athlon X2 Processors, providing high-speed processing capabilities and advanced features. The computer employs a Lithium Ion battery that allows it to be battery-operated for a longer period of time. The display uses 17-inch WXGA+ LCD panel, at a resolution of 1440 by 900 pixels. The Socket S1 supports BTO/CTO for the CPU so that the system can be designed to suit your needs.

Battery Charge When the AC adapter is attached, the battery is charged by off-state charge when the system is powered off or by on-state charge when it is powered on.

6B1.7 Batteries

Table 1-5 Quick/Normal Charging Time
State Off-State Charge On-State Charge 6/9 Cell 6/9 Cell Charge Time About 4 hours max. 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. 2. 3. The battery becomes fully charged. The AC adapter or battery pack is removed. 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. 2. The current in the battery charging circuit drops below the predetermined value. The charging time exceeds the fixed limit.
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.

Appendix F

BIOS Rewrite Procedures

This Appendix explains how to rewrite the system BIOS program when you update the system BIOS. Tools To rewrite the BIOS, you need the following tool: BIOS/EC/KBC rewriting disk for the computer that has renewed BIOS data. Rewriting the BIOS 1. Set the system to boot mode. 2. Turn off the power to the computer. 3. Remove the external cable and PC card. 4. Connect an external FDD and insert the BIOS/EC/KBC rewriting disk into either the external FDD. 5. Turn on the power while holding down the [F12] key (on the left of the space key). (Keep holding down the key until a message appears on the screen.) The BIOS rewriting starts. 6. When the process is completed, eject the BIOS/EC/KBC rewriting disk and the system is automatically reset.

Appendix G EC/KBC Rewrite Procedures
This Appendix explains how to rewrite the EC/KBC system program when you update the EC/KBC system.
To rewrite the EC/KBC, you need the following tool: BIOS/EC/KBC rewriting disk for the computer

Rewriting the EC/KBC

1. Set the system to boot mode. 2. Turn off the power to the computer. 3. Remove the external cable and PC Card. 4. Connect an external FDD and insert the BIOS/EC/KBC rewriting disk into either the external FDD. 5. Turn on the power while holding down the [F12] key. (Keep holding down the key until a message appears on the screen.) The EC/KBC rewriting starts. 6. When the EC/KBC rewrite is completed, the system is automatically turned off. Note: 1. Rewrite the EC/KBS only when instructed by a diagnostic disk release notice. 2. Connect the AC adapter to the computer when you rewrite the EC/KBC. 3. Do not turn off the power while you are rewriting the EC/KBC. If the rewrite fails, it might be impossible to start up the computer. 4. If you fail to rewrite EC/KBC, then when you next turn on the power, a message may be displayed that the contents of the EC/KBC have been erased. In this case, insert the BIOS/EC/KBC rewriting disk, and the EC/KBC will be rewritten. 5. Normally it takes about 30 seconds to rewrite the EC/KBC. It may take 3 minutes (maximum), depending on the conditions of the computer or ICs. The computer is not hung up. Allow sufficient time. Never reboot or turn off the power to the computer before the rewriting is completed.
