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 wrong-
size screw can damage the notebook. (The symbol at the left represents an M2.5 × 4 mm T-head
screw.)

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
 
HP Pavilion ze4100, Compaq Evo Notebook 1010v, and Presario 1100 notebooks 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
 • 
#1 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.

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

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
.)
