NOTE: Before you begin this procedure, make sure that the SYSTEM SWITCH option in the System Setup program is set to ON/OFF. For instructions, see "Using the System Setup Program" in Chapter 2. 1. Turn off the computer and peripherals, and disconnect them from AC power. Disconnect any attached peripherals from the computer. 2. Make sure that the AC adapter is connected to the computer and to AC power, or confirm that a fully charged battery is properly seated in its compartment. 3. Turn on the computer. Is the display on? Allow one minute for the computer to initialize its components before checking for signs of power. Yes. The entire computer is receiving power; the problem is resolved. No. Adjust the brightness and contrast of the display. If the display still does not show an image, continue to step 4. 4. Turn off the computer, and reseat (remove and reinstall) any installed memory modules. To remove a memory module, carefully spread apart the inner metal tabs of the memory module socket just far enough for the memory module to disengage from the socket (the module should pop up slightly). Then lift the memory module away from the socket. To reinstall a memory module, align the memory module's edge connector with the slot in the center of the memory module socket. Press the memory module's edge connector firmly into the socket. Pivot the memory module down until it clicks into place. If you do not hear a sharp click, remove the memory module and reinstall it. NOTE: Memory modules are keyed, or designed, to fit into their sockets in only one direction. The sockets on the system board are notched so that the memory module can be firmly seated only one way. 5. Turn on the computer. Is the display on? Yes. The entire computer is receiving power; the problem is resolved. No. The display may be defective. See "Troubleshooting the Built-In Display" found later in this section. If the display still does not work, connect an external monitor and run the Dell diagnostics. (See Chapter 4, "Running the Dell Diagnostics," for instructions.) If you cannot isolate the problem after running the diagnostics, call Dell for technical assistance. (See Chapter 5, "Getting Help," for instructions.) Troubleshooting the Diskette Drive During the power-on self-test (POST), the computer checks the diskette drive, comparing its characteristics with the system configuration information. (The diskettedrive access indicator blinks as the computer performs this check.) If a failure occurs with the drive, make a copy of the Diagnostics Checklist found in Chapter 5 and fill it out as you complete the following procedure. NOTE: Before you begin this procedure, make sure that the SYSTEM SWITCH option in the System Setup program is set to ON/OFF. For instructions, see "Using the System Setup Program" in Chapter 2. 1. Reboot the computer by pressing . Does the diskette-drive access indicator blink during the boot routine? Yes. Continue to step 2. No. Go to step 5. 2. Does the computer display a drive error message? Yes. See Table 3-2 for an explanation of the message, and then continue to step 3. No. Go to step 5. 3. Insert a bootable 1.44-MB diskette into the drive, and reboot the computer. 4. Does the diskette-drive access indicator blink during the boot routine, and does the drive boot the operating system? Yes. The diskette drive problem has probably been resolved. If you continue to experience trouble, continue to step 5. No. Continue to step 5. 5. Call Dell for technical assistance. See Chapter 5, "Getting Help," for instructions. 3-22 Dell Latitude XPi CD Reference and Troubleshooting Guide
