2.1 Troubleshooting
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 9. LAN
2. System Board 10. Sound
3. 3.5" USB FDD 11. SD card slot
4. 2.5" HDD 13. Tablet pen
5. Keyboard 14. Wireless LAN
6. Display 15. Bluetooth

8. Modem
The Detailed replacement procedures are given in Chapter 4. Test Program operations are
described in Chapter 3.
The following tools are necessary for implementing the Diagnostics procedures:
1. Diagnostics Disk (Test program for maintenance)
2. Phillips screwdrivers
NOTE: Be sure to use the PH point size “0” screwdriver complying with the ISO/DIS
8764-1:1996. Use, however, the PH point size “1” screwdriver for screws fixing the
expansion memory slot cover and the keyboard.
3. Screwdriver for LH sticks
4. Toshiba MS-DOS system FD
5. Work disk (for FDD testing)
6. Cleaning disk kit (for FDD head cleaning)
7. A set of tools for debug port test (test cable, test board, RS-232C cross cable, display,
D port FD)
8. PC with a serial port (for displaying debug port test result)
9. Wraparound connector for PC card
10. Tester
11. External CRT
12. External USB Keyboard
13. External USB mouse
14. Headphone
15. Microphone
16. RJ-11 connector checker LED
17. LAN wraparound connector
18. PC (for infrared communication test and wireless LAN test)

2.2 Troubleshooting Flowchart
Use the flowchart in Figure 2-1 as a guide for determining which FRU malfunctions. Before
going through the flowchart steps, check the following:
Make sure that Toshiba Windows
®
XP Tablet PC Edition is installed on the hard disk.
Non-Toshiba operating systems can cause the computer malfunction.
Make sure all optional equipment is removed from the computer.
Make sure the USB FDD is empty.

2.2 Troubleshooting Flowchart 2 Troubleshooting
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, ASYNC test, Real timer test,
NDP test or expansion test, perform the System Board Troubleshooting Procedures in
Section 2.4.
2. If an error is detected on the Keyboard test, perform the Keyboard Troubleshooting
Procedures in Section 2.7.
3. If an error is detected on the Display test, perform the Display Troubleshooting
Procedures in Section 2.8.
4. If an error is detected on the Floppy disk test, perform the USB FDD Troubleshooting
Procedures in Section 2.5.
5. If an error is detected on the Hard disk test, perform the HDD Troubleshooting
Procedures in Section 2.6.
6. If an error is detected on the modem test, perform the Modem Troubleshooting
Procedures in Section 2.10.
7. If an error is detected on the LAN test, perform the LAN Troubleshooting Procedures
in Section 2.11.
8. If an error is detected on the sound test, perform the Sound Troubleshooting
Procedures in Section 2.12.
9. If an error is detected on the wireless LAN test, perform the Wireless LAN
Troubleshooting Procedures in Section 2.15.

2 Troubleshooting Procedures 2.3 Power Supply Troubleshooting
2.3 Power Supply Troubleshooting
The power supply controller controls many functions and components. To determine if the
power supply is functioning properly, start with Procedure 1 and continue with the other
Procedures as instructed. The procedures described in this section are:
Procedure 1: Power Supply Icon Check
Procedure 2: Error Code Check
Procedure 3: Connection Check
Procedure 4: Quick Charge Check
Procedure 5: Replacement Check

2.3 Power Supply Troubleshooting 2 Troubleshooting
Procedure 1 Power Supply Icon Check
The following two icons indicate the power supply status:
Battery icon
DC IN icon
The power supply controller uses the power supply status with the Battery icon and the DC IN
icon as listed in the tables below.
Table 2-1 Battery icon

Portege M200 Maintenance Manual (960-457) 2-7
2 Troubleshooting Procedures 2.3 Power Supply Troubleshooting
When icons are blinking, perform the following procedure.
1. Remove the battery pack and the AC adapter and cut off the power supply to the
computer by force.
2. Re-attach the battery pack and the AC adapter.
If icons are still blinking after the operation above, check the followings:
Check 1 If the DC IN icon blinks orange, go to Procedure 2.
Check 2 If the DC IN icon does not light, go to Procedure 3.
Check 3 If the battery icon does not light orange or green, go to Procedure 4.
CAUTION: Use a recommended AC adapter (G71C0002S310).
