QOSMIO G20 Maintenance Manual (960-511) |
Preface
This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer QOSMIO G20.
NOTE: Each model of QOSMIO G20 has a different configuration. For each model’s configuration, refer to the parts list dedicated to it.
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. Be sure to use the PH Point size “0” and “1” screwdrivers complying with the ISO/DIS 8764-1:1996. 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.
