Removing a SDRAM Module
(User-Replaceable)
The notebook has no system memory built into its motherboard, but has two slots for SDRAM modules. One slot contains an SDRAM module that was factory installed.
Note Omnibook XE4100 models use only PC133 SDRAM modules, and Omnibook XE4500 models use only DDR266 SDRAM modules. Using the wrong type of module prevents the notebook from booting.
Caution
Handle the SDRAM module only by its edges and provide proper grounding, or you might damage the module through electrostatic discharge.
Required Equipment
· Small Phillips screwdriver.
Removal Procedure
1. Unplug the AC adapter, if present, and then remove the battery. 2. On the bottom of the notebook, loosen the captive screws holding the SDRAM door, and then remove the door. 3. Press outward on the latches at the sides of the SDRAM module to release it (the SDRAM module pops up). 4. Carefully pull the SDRAM module out of the connector.
Figure 2-3. Removing an SDRAM Module Reassembly Notes
· Carefully press the SDRAM module into the connector at an angle of about 30°, until it is fully inserted. Then press down on both sides of the SDRAM module until the latches snap closed.

Recovering the Factory Software
The following procedure describes how to recover the notebook's original software and operating system. This process can take up to 15 minutes to complete. (For more information about recovering the factory software installation, see the readme.txt file in the root directory of the Recovery CDs.)
Caution
Do not interrupt the following process or unplug the AC adapter until the process completes.
1. Connect the AC adapter to the notebook. 2. Insert Recovery CD disk 1 into the notebook's CD/DVD drive. If the notebook is turned off, use a pin or straightened paper clip to press the release switch on the drive door to open it. 3. Turn on or restart the notebook. 4. When the HP logo appears, press Esc to display the Boot menu. 5. Use the arrow keys to select the CD/DVD drive as the first boot device, then press Enter. 6. When the Recovery CD dialog box appears, follow the displayed instructions. If prompted, accept the recommended partition size. To create the Utility partition without installing the factory software, click Advanced and select not to install the operating system. If the hard disk is partitioned into several logical drives, you can install the factory software on drive C without affecting other drives. Click Advanced and select to restore only the C partition. 7. When prompted to reboot the notebook, press Ctrl+Alt+Del and follow any instructions that appear.

Reassembly Notes
Caution
Each time you install a new CPU module, you must also replace the heat sink's thermal pad to maintain optimum heat transfer. Use a sharp knife or scraper to carefully remove the old thermal pad from the heat sink, then attach the new thermal pad.
· The CPU module is keyed for installation, and can be inserted only one way. · Carefully insert the CPU module into the motherboard, and turn the lock screw one-half turn clockwise to secure the CPU module. · Be sure to replace the thermal pad on the heatsink, as described in the reassembly notes on page 2-28.

(HP Authorized Service Providers Only)
Required Equipment
· Small Phillips screwdriver.
Removal Procedure
Note: Before Replacing the Motherboard
If possible, record the computer's electronic serial number before you replace the motherboard. You will then store the electronic serial number in the EEPROM on the new motherboard using the Service Utility floppy disk. 1. Download the service package for the Omnibook XE4100 (technology code KC) or Omnibook XE4500 (technology code KB) from the Partnership web site (see page vii), and create a Service Utilities floppy disk as described in the package's Readme file. 2. Plug in an AC adapter. 3. Insert the Service Utilities floppy disk in the floppy drive. 4. Turn on the notebook. When the HP logo appears (on either the built-in display or the external monitor), press Esc to display the boot menu, then choose Removable Device and boot from the floppy disk. 5. Select the Serial Number option from the boot menu. 6. When prompted, type A for the automatic update option. This stores the current system data from the old motherboard on the floppy disk.

Caution: Wireless Models
Be careful when removing and attaching antenna cables. Damage to cables or connectors can degrade performance.
3. Wireless models only: Remove the mini-PCI door and unplug the two antenna cables from the mini-PCI card. Do not remove the mini-PCI card at this time. 4. Remove the four screws that attach the motherboard to the bottom case. 5. From the back of the notebook, remove the six standoffs (two each from the external monitor port, serial port, and parallel port). 6. Remove the antenna cable from the metal holder on the motherboard. 7. Carefully lift the motherboard out of the bottom case. 8. If present, remove the modem port cover.

Reassembly Notes
Important
After replacing the display assembly or motherboard, you must use the Service Utilities floppy disk to reprogram the EEPROM on the motherboard for the new display. 1. Download the Omnibook XE4000 Series service package from the Partnership web site (see page vii), and create a Service Utilities floppy disk as described in the package's Readme file. 2. Plug in an AC adapter. 3. Insert the Service Utilities floppy disk in the floppy drive. If the unit has no internal floppy drive, connect a USB floppy drive 4. Turn on the notebook. 5. When you see the HP logo, press ESC to display the boot menu, then boot from the floppy drive. 6. Select the option to update the display/LCD identification stored on the motherboard.
· If you are replacing the CPU module, you must also replace the thermal pad on the heat sink (see page 2-29). Wireless Models Only · Before installing the motherboard, make sure the round coaxial cables from the antenna PCAs are held in place by the clips in the bottom case. · Make sure there is sufficient length to the front antenna PCA cables so they can easily be connected to the mini-PCI card.
Reassembly Procedure
Caution
Be extremely careful when replacing the motherboard. The motherboard has EMI springs attached to it that can bend very easily. Bending any EMI spring could cause a motherboard short.
Note: Reprogramming the BIOS IC A new BIOS IC contains only enough basic programming to enable the notebook to boot. After installing a new motherboard, you must reprogram the BIOS IC, preferably with the latest BIOS-- see page 2-36.

1. Remove the following components from the old motherboard and install onto the new motherboard: · CPU module · Wireless LAN mini-PCI card (if present) · SDRAM modules 2. Follow the reassembly notes in the section entitled "Removing the Motherboard" on page 2-33.
Note: After Replacing the Motherboard
If present, insert the modem port cover into the modem port opening. Afterwards, you must use the Service Utility floppy disk to store the system data and display information in the EEPROM on the new motherboard. To do so: 1. Plug in an AC adapter. 2. Insert the Service Utilities floppy disk in the floppy drive. 3. Turn on the notebook. 4. If you hear 5 beeps, press F1 to update the display data stored on the motherboard. Let the notebook reboot and go to the next step. 5. Select the Serial Number option from the boot menu. 6. If you successfully stored system data on the floppy disk before removing the old motherboard, type A for the automatic update. This restores the old system data on the new motherboard. If you did not store system data, type M for the manual update option. Enter the serial number from the bottom of the notebook--you might have to contact an HP support center to do this.
