How to Disassemble a Wireless Microsoft Optical Mouse 3000

Unlike older "ball and roller" style mice, optical mice use camera and digital technology, which usually does not require extensive cleaning or additional maintenance. That being said, a Microsoft Wireless Mouse 3000 can develop tracking or other problems that may require a look inside the case.

Step

Shut down the computer or laptop. Unplug the Microsoft Optical Mouse 3000 wireless USB receiver from the computer's USB port.

Step

Depress the silver button located at the base of the mouse to release the unit's battery cover. Remove the battery cover and the single AA battery inside the casing.

Step

Use a small flat-head or jeweler's screwdriver to gently pry off the unit's left and right mouse button assembly. (The left and right mouse buttons are comprised of a single piece of molded plastic that comes off as a unit.)

Step

Turn the mouse over and use your fingernail to pry off the four rubberized feet on the bottom cover. Remove the four screws (one under each rubberized foot) with a cross-head screwdriver.

Step

Slide the two sections (top and bottom) of the mouse casing apart. The bottom section of the mouse houses the circuit board, antenna, scroll wheel and other miscellaneous parts. The circuit board will easily lift out of the bottom section once the four case screws are removed.
