Qosmio X300 Maintenance Manual
Preface
This maintenance manual describes how to perform hardware service maintenance for the Toshiba Personal Computer Qosmio X300, referred to as the Qosmio X300 Series 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 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. Power input monitor
y Checks whether the AC adapter (DC power supply) is connected to the computer. y Checks whether the battery pack is connected to the computer. y Monitors the DC power supply input voltage (AC Adapter output voltage).
2. Power supply's internal control
y Turns on and off the battery pack charging power supply. y Issues a charging current instruction to the PWM control IC of the battery pack charging
power supply.
y Controls the supply of DC power supply input (AC Adapter output) to the power supply
unit.
y Controls the supply of power to the system block (load/logic circuit side). y Controls forced shutdown if the power supply malfunctions.
3. Logic circuit control
y Instructs the gate array to enable/disable tuning the power on. y Controls power-on/off operation.
4. Status display
y Shows DC-IN (Red Color) y Shows Power (Red/Amber) y Shows Main Battery charging (Red/Amber Color).
5. External interface

1.5 Batteries

The computer has the following two types of batteries:
Main Battery Pack Real Time Clock (RTC) Battery

1.5.1 Main Battery

The main battery pack serves as the computer's main power source when the AC adapter is not attached. The main battery maintains the state of the computer so that it can resume it.

1.5.2 Battery Charging Control

Battery charging is controlled by EC KB926. When the AC adapter and battery pack are attached to the computer, the EC KB926 controls the charge on/off state and detects a full charge.
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.
Table 1-3 Quick/Normal Charging Time
State Charge Time
Off-State Charge 8 Cell About 4 hours max
On-State Charge 8 Cell About 12 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.
Qosmio X300 Maintenance Manual 1-16
Error! Style not defined. Error! Style not defined. 1 Hardware Overview
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.

1.5.3 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.

If you know the location of the malfunction, turn directly to the appropriate section of this chapter. If the problem is unspecified, use the flowchart in Figure 2-1 as a guide for determining which troubleshooting procedures to execute. Before performing any troubleshooting procedures, verify the following:
z Ask the user if a password is registered, if it is, ask him or her to enter the password. z Verify with the customer that Toshiba Windows Vista is installed on the hard disk.
Operating systems that were not preinstalled by Toshiba can cause the computer to malfunction.
z Make sure all optional equipment is removed from the computer. z Make sure the floppy disk drive, if installed, is empty. If no FDD module is installed,
