Internal Design

The motherboard PCA is the central component of the notebook’s design. It plays a role in virtually all system functions. The CPU module and most other subsystems connect to the motherboard.

The following figure shows the connections among the notebook’s replaceable electronic modules. Table 1-9 on page 1-15 lists the roles that these modules play in the notebook’s functional subsystems.

Caution

Always provide proper grounding when performing repairs. Without proper grounding, an electrostatic discharge can damage the notebook and its components.

Notes

Reassembly steps are the reverse of the removal steps. Reassembly notes are included at the end of each section below.

Symbols like these are displayed throughout this chapter to show approximate full-size screw outlines. You can use these to verify the sizes of screws before you install them. Installing a wrongsize screw can damage the notebook. (The symbol at the left represents an M2.5 × 4 mm T-head screw.)

Removal and Replacement

HP Omnibook XE4100/XE4500

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.

Removing the Wireless LAN Mini-PCI Card

(User-Replaceable)

Certain notebooks include a wireless LAN mini-PCI card under the mini-PCI door on the bottom of the notebook.

Caution

Handle the Mini-PCI card only by its edges and provide proper grounding, or you might damage the card 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 Mini-PCI door, and then remove the door.

Caution

Be careful when connecting and disconnecting the antenna cables from the mini-PCI card. Damaged cables or connectors can degrade notebook performance.

3.Disconnect the two antenna cables from the mini-PCI card.

4.Press outward on the latches at the sides of the mini-PCI card to release it (the mini-PCI card pops up).

5.Carefully pull the mini-PCI card out of the connector.

Figure 2-4. Removing the Mini-PCI Card

Reassembly Notes

•Carefully press the mini-PCI card into the connector at an angle of about 30°, until it is fully inserted. Then press down on both sides of the mini-PCI card until the latches snap closed.
