How to disassemble HP X4500 mouse to replace button switch

@MJB52,

Welcome to our HP Community forum!

HP X4500 Mouse Disassembly for Switch Replacement:

The HP X4500 is a wireless optical mouse, generally built with plastic clips and minimal screws, not particularly designed for easy user serviceability. However, if you're handy and already have microswitches (like Omron D2FC-F-7N replacements), yes, it should be technically possible to disassemble and replace the button switch.

Disassembly Overview:

1. Power off and remove batteries.

2. Remove the bottom sticker — often conceals 1–2 screws.

3. Unscrew and gently pry open the upper and lower shells using a plastic spudger or guitar pick (not metal tools).

4. Access the PCB — the switches are mounted to it and may be soldered.

5. Desolder the faulty switch and solder a new one in place.

6. Reassemble in reverse order.

Is It Worth It? Here's the Real Question:

Criteria                                                         Value

Mouse MSRP	~$25–$30
New switch (Omron, etc.)	~$2–$5
Time & effort (if soldering required)	30–60 minutes
Tools needed	Soldering iron, spudger, Torx/Phillips driver
Skill level	Moderate (especially if soldering involved)

Verdict:

If you enjoy DIY repairs, have the tools, and dislike e-waste: go for it.

Otherwise, it's probably not worth it economically unless the mouse has sentimental value or is part of a matched set (e.g., with an HP All-in-One).

Step-by-step Video Walkthrough:

Check out this repair video (it’s for a similar HP model, but the process parallels the X4500): https://youtu.be/gGT8F52xdiE.

This clip shows:

• Removing screws hidden under stickers

• Prying the upper shell

• Desoldering the faulty switch

• Resoldering the new microswitch

Written Disassembly Steps:

1. Remove batteries and set them aside.

2. Lift off or peel the bottom sticker—you should find one (sometimes two) small screws underneath, see: Mouse disassembly - HP Support Community - 587143 and: Wireless x4500 Mouse Laser Sensor Not Working - HP Support Community - 7033922.

3. Unscrew and carefully separate the top and bottom halves using a plastic pry tool.

4. Expose the PCB, where the left/right microswitches are located.

5. Desolder the malfunctioning switch—these are standard microswitches, so replacements such as Omron D2FC-F-7N (~$2–5) fit well.

6. Install the new switch, solder it carefully, reassemble, and test for proper click feel.

Tips & Warnings:

• Work on an anti-static mat to protect internal electronics.

• Use plastic spudgers, not metal, to avoid cracking the shell.

• Microsoldering does require precision -steam iron or probe iron might help.

• Note: On some HP mice, the clicker is clip-mounted rather than glued -so slow, steady pressure helps when prying it open.

---

Again, Should You Do It?

• Yes, if you're equipped with basic soldering tools & skills, replacement microswitches, and enjoy hands-on repair.

• No, if you value time or lack soldering experience -the parts and effort may outweigh buying a fresh mouse (~$25‑$30).

User Manual & Firmware Resources:

HP’s official support site used to offer a user manual and downloads for the X4500; helpful for diagrams or parts seating, but apparently no longer: HP X4500 Wireless (Black) Mouse | HP® Support ("Looks like we don’t have support content for you here.") -sorry about that.

Only thing I was able to find was the "HP x4500 Quick Setup": HP X4500 QUICK SETUP Pdf Download | ManualsLib.

Thanks for the comprehensive reply. After removing the smooth slide strips at the front and rear of the mouse base, four torx T6 security screws (with a pin in the middle) were exposed. Removing these screws allowed the top and bottom parts of the shell to be separated.  The switches in my model H2W16AA are different to those in the video.  Once I find a replacement switch it will be easy to solder it in.

Additional info.

The switches in the model H2W16AA mouse are EVQP0E07K.
