ThinkPad 240 Hardware Maintenance Manual About This Manual This manual contains service and reference information for the IBM ThinkPad 240 products. Use this manual along with the diagnostics tests to troubleshoot problems effectively. There are two models of LCD panel used with the ThinkPad 240: LCD Type A and LCD Type B. Check the last five letters of the unit's serial number you are servicing to determine the model.
Use new nylon-coated screws when you replace FRUs. Be extremely careful during write operations such as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten. Replace FRUs only for the correct model.
and some symptoms that may indicate that the system was subjected to stresses beyond normal use: The following is not covered under warranty: LCD panel cracked by applying excessive force or from being dropped Scratched (cosmetic) parts Cracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force Damage caused by liquid spilled into the system Damage caused by the improper insertion of a PC Card or the installation of an incompatible card
5. Close the keyboard. 6. Power on the computer and wait until POST ends. 7. Verify that the password prompt does not appear. Supervisor and hard disk drive passwords: The Supervisor Password and hard disk drive password are security features that are used to protect the system and the hard disk drive data from unauthorized access. No overriding capability is provided, so it cannot be replaced if they are forgotten. If the customer forgets the Supervisor Password, the system board must be replaced.

The following shows the location of each indicator symbol and the meaning of each indicator. Pad Think Symbol Color Meaning (1) Battery status Green Enough battery power remains for operation.
Symbol Color Meaning (3) Drive in use Orange Data is being read from or written to the hard disk drive. Do not enter hibernation mode or power off the computer when this indicator is on. (4) Numeric lock Green The numeric keypad on the keyboard is enabled. You enable or disable the keypad by pressing and holding the Fn key, and pressing the NumLk key. For details, see the User's Reference. (5) Caps lock Green Caps Lock mode is enabled.
1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to recreate the failure by running the diagnostic test or by repeating the same operation. Note: To run the diagnostics, refer to “Running the Diagnostics” on page 23 3. Use the following table with the verified symptom to determine which page to go to. Search the symptoms column and find the description that best matches your symptom; then go to the page shown in the "Go to" column.
2. Go to Diagnostics on the main menu and select Other Devices. 3. Follow the description in the window. If the test detects a fan ASM problem, replace the fan. Keyboard and Auxiliary Input Device Checkout Note: Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated on the connector.
Memory errors might stop system operation, show error messages on the screen, or hang the system. Use the following procedure to isolate memory problems: 1. Turn off the computer and remove any installed DIMM from its slot. 2. Boot from the diagnostics diskette and start the program. 3. Go to Diagnostics on the main menu and select Memory Test.If an error appears, replace the system board. 4. Turn off the computer and reinstall the DIMM; then turn on the computer.
Checking the AC Adapter: You are here because the computer fails only when the AC Adapter is used: If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation. If the operational charge does not work, go to “Checking the Operational Charging.” Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure. Pin Voltage (V dc) 1 +15.5 to +17.
Note: Signal lines, not used in these steps, are used for communications between the system and the battery. 3. If the voltage is less than 10.6V, the battery ASM has been discharged, recharge the battery ASM. If the voltage is still less than 10.6V, replace the battery. TrackPoint Checkout If the external mouse is connected, the TrackPoint does not work. In this case, please detach the external mouse to check the TrackPoint.
I/O Ports Checkout Note: Be sure to enable the serial and parallel ports in the BIOS setup utility before performing diagnostics tests on the I/O ports. Also, be sure to write down the I/O address for the serial port to identify the port in the diagnostic test. Do perform a diagnostics checkout on the I/O ports: 1. Boot from the diagnostics diskette and start the program. 2. Go to Diagnostics on the main menu and select Serial Ports or Parallel Ports.
The computer exits standby and resumes operation when any key is pressed. Suspend Mode: In suspend mode, the following occurs: The LCD is powered off. The hard disk drive is powered off. The CPU stops. Events that cause the computer to enter suspend mode: Suspend mode requested by the Fn key (Fn+F4). The Lid is closed. The specified time has elapsed. Battery low occurs and hibernation conditions are insufficient.
Timer conditions are satisfied in suspend mode when hibernate by timer is enabled. A critically low battery condition occurs. The power switch is pressed. (BIOS Setup) The computer exits hibernation mode and resumes operation when the power-on switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and the system status is restored from the hard disk drive.
Symptom-to-FRU Index The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first. Note: Perform the FRU replacement or actions in the sequence shown in the FRU/Action columns. If a FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also be used to help you decide the next possible FRUs to be replaced when servicing a computer.

3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist. Undetermined Problems You are here because the diagnostic tests did not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRUs).
CE Utility Program Diskette Writing the VPD Data The EEPROM on the system board contains the Vital Product Data (VPD) — that is, a computer serial number and a system board serial number. When you replace the system board, restore the computer serial number using the VPD Data Utility in the ThinkPad CE Utility Diskette. The serial number label is attached to the computer. Flash UUID The EEPROM on the system board contains the Universal Unique ID (UUID) — that is, for Microsoft or Internet use.
FRU Removals and Replacements This section contains information about removals and replacements. Do not damage any parts. Only certified and trained personnel should service the computer. The arrows in this section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal.
LCD FRU Replacement Notice: The TFT LCD for the notebook computer contains over 2,359,296 thinfilm transistors (TFTs). A small number of missing, discolored, or lighted dots (on all the time) is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is 8 or more.
