Caution
 
Always provide proper grounding when performing repairs. W ithout 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.)

							2-4 Removal and Replacement HP Omnibook 6000/6100
Removing the Battery
(User-Replaceable)
Required Equipment
 · None.
Removal Procedure
 · Slide the battery’s release latch, then lift the battery out of its compartment.
 
 Figure 2-2. Removing the Battery
Reassembly Notes
 · Insert the front (rounded) end of the battery into the battery compartment on the bottom of the
computer, and lower the back end in until it clicks into place.

Removing a Plug-In Module
(User-Replaceable)
Required Equipment
 · None.
Removal Procedure
 1. Press the button on the module release latch, and slide the latch toward the front of the computer.
 
 Figure 2-3. Removing a Module
 2. Grasp the module and pull it out.

							2-6 Removal and Replacement HP Omnibook 6000/6100
Removing an SDRAM Module
(User-Replaceable)
The computer has no SDRAM on its motherboard, but has two slots for that hold two SDRAM
modules. One slot contains a SDRAM module installed at the factory.
  Caution
 
Handle the SDRAM module only by its edges and provide proper grounding, or you might damage
the board by electrostatic discharge.
Required Equipment
 · Small Phillips screwdriver.
Removal Procedure
 1. Unplug the AC adapter, if present, and remove the battery. Remove the secondary battery if one is
installed.
 2. Turn the unit bottom-side up, loosen the one or two screws holding the SDRAM cover (the cover
may retain the screws), and remove the cover.
 3. Release the two latches at the sides of the SDRAM module, so the free edge of the board pops up.
 4. Pull the board out of the connector.
 
 Figure 2-5. Removing a SDRAM Module
Reassembly Notes
 · Gently press the SDRAM module into the connector at about a 30° angle, until it is fully inserted.
Then press down on both sides until the latches snap closed.

Removing the Hard Disk Drive
(User-Replaceable)
Required Equipment
 · Small Phillips screwdriver.
Removal Procedure
 1. Unplug the AC adapter, if present, and remove the battery. Remove the secondary battery if one is
installed.
 2. Turn the unit bottom side up and remove all hard drive screws.
 3. Raise the cover on the end of the drive so that its retainer tab is free of the computer casing, then
gently pull the hard drive out of the computer.
 
 
 Figure 2-6. Removing the Hard Disk Drive
 4. Remove all screws from the holder and drive case, then lift the drive out of the holder.
 5. Notice that the hard drive has a pin connector attachment at one end. Carefully remove this
connector from the end of the drive. Work alternately at each end so that the connector slides off
evenly without bending the connector pins.

 Figure 2-7. Removing the Hard Disk Case
 · Slide the cover down into place so the retainer tab engages the casing.
 · Carefully put the pin connector back onto the pins on the end of the new hard drive. Work at each
end alternately so that the connector slides on evenly without bending the connector pins.
  Important
 
If you are installing a new hard drive, create a Utility partition on the drive before loading any
software—see “Creating a Utility Partition,” below.
