Indicator Panel System Overview 1-3 The portable computer has nine indicators: six on the display assembly’s indicator panel and three on the keyboard assembly. Each of the six indicators on the display assembly has an identical pair of LEDs: one is visible on the indicator panel when the display is open, and the other is visible through an aperture on the outside of the display assembly when the display is fully closed. The subsections that follow describe the functions of the indicators. Power/Suspend Indicator The power/suspend indicator is a green LED. After the computer is turned on, the power/suspend indicator lights up constantly to indicate that the computer is receiving stable power. When the computer enters suspend mode, the indicator blinks once approximately every 8 seconds. Diskette-Drive Access Indicator The diskette-drive access indicator is a green LED. The indicator lights when data is being transferred to or from the diskette drive. Hard-Disk/CD-ROM Drive Access Indicator The hard-disk/CD-ROM drive access indicator is a green LED. The indicator lights when data is being transferred to or from the hard-disk drive or the CD-ROM. PC Card Access Indicator The PC Card access indicator is a green LED. The indicator lights when data is being transferred to or from an installed PC Card (also known as a PCMCIA card). Low-Battery Indicator The low-battery indicator is an amber LED. This indicator is used in conjunction with the speaker to indicate either of the following low-battery conditions: • The first low-battery warning occurs when the main battery’s charge has been depleted to 8 percent of its fully charged condition. The low-battery indicator turns on and the speaker emits five beeps. • The second and final low-battery warning occurs when the main battery’s charge has been depleted to 3 percent of its fully charged condition. The speaker beeps twice every 1 to 2 seconds for 15 seconds; then the system does a suspend-to-disk operation automatically before shutting down. Charging Indicator The charging indicator is an amber LED. The indicator turns on when the main battery begins charging and blinks to show the battery is fully charged. 1-4 Dell Latitude XPi CD Service Manual Keyboard Indicators The keyboard controls the operation of the numeric lock (Num Lock) indicator, the capitals lock (Caps Lock) indicator, and the Scroll Lock indicator, all of which are visible through apertures at the top of the keyboard. These indicators are associated with thekey, the key, and the key; when lit, the LEDs indicate the active state of these keys. Controlling Computer Power The power button does not directly control power to the computer. Instead, when you slide the power button toward the front of the computer and then release it, the button momentarily closes the power switch on the system board. The power switch sends a signal to the power management controller, signaling the controller to initiate a change of state of the computer’s power. The resulting power state depends on the present power state. The following subsection gives a description of the power states. Power States Sliding the power button toward the front of the computer initiates a change from the current power state to a different state. The protocols for the power state changes are as follows: • If the computer is off (no indicators on) and the display is open and/or an external monitor is attached to the computer, sliding the power button initiates a boot operation. • If the computer is off, if the display is closed, and if no external monitor is attached, sliding the power button causes the computer to run the POST and then turn off. • If the computer is on and the SYSTEM SWITCH option in System Setup is set to ON/OFF, sliding the power button turns off the computer. • If the computer is on and the SYSTEM SWITCH option in System Setup is set to S2D/RFD, sliding the power button causes the computer to enter suspendto-disk mode. • If the computer is in suspend mode (the power/suspend indicator flashes every 8 seconds), if the SYSTEM SWITCH option in System Setup is set to ON/OFF, and if the display is open or an external monitor is attached, sliding the power button turns off the computer. • If the computer is in suspend mode (the power/suspend indicator flashes every 8 seconds), if the SYSTEM SWITCH option in System Setup is set to S2D/RFD, and if the display is open or an external monitor is attached, sliding the power button causes the computer to enter suspend-to-disk mode. System Overview 1-5 • If the computer is in suspend mode (the power/suspend indicator flashes every 8 seconds), if the display is closed, and if no external monitor is attached, sliding the power button has no effect on the power state. The computer remains in suspend mode. • If the computer is in suspend-to-disk mode, sliding the power button causes the computer to initiate the resume-from-disk operation.

System Overview 1-13 1-14 Dell Latitude XPi CD Service Manual Chapter 2 Initial Procedures T his chapter describes initial procedures that can help you diagnose a computer problem. These procedures can often reveal the source of a problem or indicate the correct starting point for troubleshooting the computer. Dell recommends that you perform these procedures in the order they are presented in this manual. Initial User Contact When you first contact a user who has a computer problem, ask the user to describe the problem and the conditions under which it occurs. A verbal description can often indicate the cause of a problem or indicate the appropriate troubleshooting procedure to use. After the user describes the problem, follow these steps: 1. Ask the user to back up any data on the hard-disk drive if the system’s condition permits. See “Maintaining Your Computer” in the online System User’s Guide. 2. Ask the user to try to duplicate the problem by repeating the operations he or she was performing at the time the problem occurred. Can the user duplicate the problem? Yes. Proceed to step 3. No. Proceed to the next section, “Visual Inspection.” 3. Observe the user to determine whether he or she is making an error, such as typing an incorrect key combination or entering a command incorrectly. Is the problem a result of user error? Yes. Instruct the user in the proper procedure, or direct him or her to the appropriate user documentation for a description of the correct procedure. No. Proceed to the next section, “Visual Inspection.” Visual Inspection The visual inspection consists of a quick inspection of the exterior of the computer and any attached peripherals, including making any necessary corrections. For information about the proper removal and installation of computer Initial Procedures 2-1 components, as instructed in the following procedures, see Chapter 4, “Removing and Replacing Parts.” CAUTION: Before you proceed with the visual inspection, ensure that the user has saved all open files and exited all open application programs if possible. To perform a visual inspection, follow these steps: 1. Turn off any attached peripherals. 2. Determine the present power state of the computer. Look at the indicators to determine which of the following conditions apply, and then turn off the computer, taking the actions listed for that condition: • Power/suspend indicator is blinking approximately every 8 seconds — The computer is in suspend mode. Open the display and press any key to return the computer to the power-on state. If the computer does not turn on, press to return from battery-swap mode. Then slide the power button to turn off the computer. • Low-battery indicator is on or blinking — A low-battery warning occurred; open the display and slide the power button to turn off the computer. • Low-battery and charging indicators are both blinking — A defective battery is detected or the computer is too warm; slide the power button to turn off the computer. • All indicators remain off — The computer is already turned off or is in suspend-to-disk mode. 3. Verify that the exterior of the computer is free of any obvious physical damage. 4. If the computer is operating from an AC adapter, verify the following: • The AC adapter’s AC power cable is connected to the AC adapter and the power source. • The AC adapter’s DC power cable is properly connected to the computer’s DC power input connector. • The AC adapter and cables are free of any obvious physical damage. NOTE: If the charging indicator and low-battery indicator flash continuously while the computer is connected to AC power, disconnect the computer from AC power and move it to a cooler location. When the computer has cooled to room temperature, reconnect it to AC power and continue charging the battery. If the computer is not allowed to cool, the battery stops charging before it reaches full capacity. 2-2 Dell Latitude XPi CD Service Manual 5. If the computer is operating from battery power, remove the main battery assembly, verify that it is free of any obvious physical damage, and then reinsert the battery assembly into its compartment. 6. Turn off the computer. Remove the hard-disk drive, verify that it is free of any obvious physical damage, and then reinsert the drive into its compartment. 7. Remove any installed PC Cards from the PC Card slot, verify that they are free of any obvious physical damage, and then reinsert the card(s) into the PC Card slot. 8. Remove any memory modules from the memory compartment, verify that they are free of any obvious damage, and then reinstall the memory modules. 9. Open the display assembly, and verify that it is free of any obvious physical damage. 10. Verify that the internal keyboard is free of any obvious physical damage and that its keys operate freely. 11. Verify that the trackball and its associated switches operate freely. 12. If an external monitor is connected, verify the following: • The monitor’s interface cable is properly attached to the VGA connector on the I/O panel. • The monitor’s power cable is attached to a power source and is free of any obvious physical damage. • The monitor’s controls are set according to the instructions in the documentation for the monitor. • The monitor and its interface cable are free of any obvious physical damage. 13. If an external mouse is connected, verify the following: • The mouse is properly connected to the keyboard/keypad/mouse connector on the computer’s I/O panel. • The mouse and its cable are free of any obvious physical damage. • The mouse’s ball and push buttons operate freely. 14. For any attached serial or parallel devices, verify the following: • The device’s interface cable connector is correctly attached to the appropriate port connector on the computer’s I/O panel. • The captive screws that secure the connectors at each end of the interface cable are secure enough to ensure a firm connection. • The attached device and its interface cable are free of any obvious physical damage. Initial Procedures 2-3 15. Turn on any attached peripherals and then the computer. Does the problem reoccur? Yes. Proceed to the next procedure, “Observing the Boot Routine.” No. No further steps are necessary. Observing the Boot Routine After you perform a visual inspection as described in the previous section, boot the computer from a diagnostics diskette and, while the boot routine is running, observe the computer for any indications of problems. NOTE: To prevent possible damage to the original diagnostics diskette, always use a backup copy of the diagnostics diskette when servicing a user’s computer. Dell recommends that users make copies of the Dell diagnostics diskette. For instructions, see “Before You Start Testing” in Chapter 4 of the Reference and Troubleshooting Guide. To observe the boot routine, follow these steps: 1. Turn off the computer and any attached peripherals. 2. Insert a diagnostics diskette into the diskette drive. Turn on all peripherals and then the computer. 3. Watch the indicators on the top of the keyboard. After all three indicators flash momentarily, the Num Lock indicator should light up and remain on. Do these indicators light up within approximately 10 seconds after the boot routine starts? Yes. Proceed to step 4. No. Troubleshoot the power subsystem. 4. While the boot routine is running, observe the computer for any of the following: • Diskette-drive and hard-disk drive access indicators — These indicators light in response to data being transferred to or from the drives. If either of these indicators fail to light during the boot routine, troubleshoot the diskette-drive or hard-disk drive subsystem, as appropriate. • Beep codes — A beep code is a series of beeps that indicates an error condition. If the computer emits a beep code, go to Table 3-1. NOTE: The computer beeps once during the boot routine. This single beep is normal and is not a beep code. • System error messages — These messages can indicate problems or provide status information. If a system error message displays, go to Table 3-2. 2-4 Dell Latitude XPi CD Service Manual 5. Observe the display for the Diagnostics Menu. Does the Diagnostics Menu display? Yes. See “Running the Dell Diagnostics” in Chapter 3. No. Proceed to step 6. 6. Insert another copy of the diagnostics diskette into the diskette drive, and reboot the computer. Does the Diagnostics Menu display? Yes. See “Running the Dell Diagnostics” in Chapter 3. No. Proceed to the next section, “Eliminating Resource Conflicts.” Eliminating Resource Conflicts Devices within the computer may require dedicated memory spaces, interrupt levels, or DMA channels, all of which must be allocated during installation of the devices. Because a device may be installed at a different time, it is possible that the same resource is assigned to two or more devices. Resource conflicts can result in disorderly or erratic computer operation or failure of the computer to operate at all. If you suspect that resource conflicts might exist, check the computer and reassign the resources as necessary. For more information about resolving conflicts, see Chapter 3, “Troubleshooting Your Computer,” in the Reference and Troubleshooting Guide. Getting Help If none of the procedures in this chapter reveal the source of the problem or lead to the proper troubleshooting steps for determining the source of the problem, call Dell for technical assistance. For instructions, see Chapter 5, “Getting Help,” in the Reference and Troubleshooting Guide. Initial Procedures 2-5 2-6 Dell Latitude XPi CD Service Manual Chapter 3 Beep Codes and Error Messages T his chapter describes beep codes and system error messages that can occur during computer start-up or, in the case of some failures, during normal computer operation. The tables in this chapter list faults that can cause a beep code or system error message to occur and the probable causes of the fault in each case. If a faulty computer does not emit beep codes or display system error messages to indicate a failure, use the Dell diagnostics to help isolate the source of the problem. See “Running the Dell Diagnostics” found later in this chapter. POST Beep Codes If the display cannot display error messages during the POST, the computer may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. The following table lists the beep codes that may be generated during POST. Most beep codes indicate a fatal error that requires replacement of the system board or other corrective actions before the computer can operate. Table 3-1.

Running the Dell Diagnostics The diagnostics contains tests that aid in troubleshooting the computer. If needed, see Chapter 4, “Running the Dell Diagnostics,” in the Reference and Troubleshooting Guide. The diagnostics diskette contains the following test groups: • • • • • • • • 3-8 RAM — Tests the main memory System Set — Tests the system board’s primary functions Video — Tests the video subsystem Keyboard — Tests the keyboard subsystem Mouse — Tests the mouse/trackball subsystem Diskette Drives — Tests the diskette drive subsystem Hard-Disk Drives (Non-SCSI) — Tests the IDE hard-disk drive subsystem IDE CD-ROM Drives — Tests the CD-ROM drive subsystem Dell Latitude XPi CD Service Manual • Serial Ports — Tests the serial communication port • Parallel Ports — Tests the parallel communication port • SCSI Devices — Tests the SCSI controller in the Advanced Port Replicator • Network Interface — Tests the network controller in the Advanced Port Replicator • Serial Infrared — Tests the IrDA communications port • Audio — Tests the built-in sound subsystem CAUTION: To prevent possible damage to the original diagnostics diskette, always use a backup copy of the diagnostics diskette when servicing a user’s system. If the user has not already made a backup copy of the diagnostics diskette, do so before you run the diagnostics. To start the diagnostics, turn off the computer, insert a diagnostics diskette into the diskette drive, and then turn on the computer. Starting the diagnostics causes the Dell logo screen to appear, followed by a message indicating that the diagnostics is loading. Before the diagnostics loads, a program tests the portion of main memory (RAM) required for loading the diagnostics. If a main memory error is detected, a message appears on the screen telling you which memory address failed. If no errors are found in main memory, the diagnostics loads and the Diagnostics Menu appears. This menu lets you choose the following options or exit to the MS-DOS prompt: • RUN QUICK TESTS • • RUN ALL TESTS — Runs selected tests from all test groups to quickly locate the failure or to indicate where further testing may be needed to isolate a failure — Runs all tests for a thorough test of the computer RUN SPECIFIC TESTS — Tests a particular area or subsystem Beep Codes and Error Messages 3-9 3-10 Dell Latitude XPi CD Service Manual Chapter 4 Removing and Replacing Parts T his chapter provides instructions for removing and replacing fieldreplaceable components, assemblies, and subassemblies.
