Internal Design

The motherboard PCA is the central component of the Omnibook’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 Omnibook’s replaceable electronic modules. Table 1-9 on page 1-15 lists the roles that these modules play in the Omnibook’s functional subsystems.

Caution

Always provide proper grounding when performing repairs. Without proper grounding, an electrostatic discharge can damage the Omnibook 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 this throughout this chapter show approximate full-size screw outlines. You can use these to verify the sizes of screws before you install them. Installing a wrong-size screw can damage the unit. (The symbol at the left represents an M2.5×5mm T-head screw.)

Removing an SDRAM Module

(User-Replaceable)

The notebook has no SDRAM built into its motherboard, but has two slots for SDRAM modules. One slot contains an SDRAM module installed at the factory.

Note

Omnibook XT6050 models use only PC133 SDRAM modules, and Omnibook XT/VT6200 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

Unplug the AC adapter, if present, and remove the battery and any secondary battery module.

On the bottom of the notebook, loosen the screws holding the SDRAM cover (the cover retains the

screws), and remove the cover. Press outward to release the latches at the sides of the SDRAM module, so that the free edge of the

module pops up. Carefully pull the module out of the connector.

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 module until the latches snap closed.

Removal Procedure

Unplug the AC adapter, if present, and remove the battery and any secondary battery module.

On the bottom of the unit, remove the hard drive retaining screws.

Raise the cover on the end of the drive so that its retainer tab is free of the notebook case, then

carefully pull the hard drive out of the computer.

Figure 2-6. Removing the Hard Disk Drive

Remove the screws from the drive and drive tray, then lift the drive out of the tray.

Notice that the hard drive has a pin connector attachment at one end. Carefully remove this

connector from the end of the drive by working alternately at each end of the connector so that it slides off evenly without bending the connector pins.
