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 1-28 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 wrong-size screw can damage the notebook. (The symbol at the left represents an M2.5 × 4 mm 
T-head screw.)

Removing the Battery 
(User-Replaceable) 
Required Equipment 
• None. 
Removal Procedure 
• Slide the battery’s release latch, then pull the battery out of its compartment. 
 
Figure 2-2. Removing the Battery 
2-4 Removal and Replacement Service Manual  
						

							 
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 ze5200, ze4200, ze4100, Compaq Evo Notebook N1050v and N1010v, and Presario 
2500, 2100, and 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. 
2. 
3. 
4. 
Unplug the AC adapter, if present, and then remove the battery. 
On the bottom of the notebook, loosen the captive screws holding the SDRAM door, and then 
remove the door. 
Press outward on the latches at the sides of the SDRAM module to release it (the SDRAM module 
pops up). 
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. 
Service Manual Removal and Replacement 2-5  
						

							 
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 
• #0 Phillips screwdriver. 
Removal Procedure 
1. 
2. 
Unplug the AC adapter, if present, and then remove the battery. 
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. 
4. 
5. 
Disconnect the two antenna cables from the mini-PCI card. 
Press outward on the latches at the sides of the mini-PCI card to release it (the mini-PCI card 
pops up). 
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.
