Another easy Saturday (wireless mouse cleaning)

Went to the library to study in the morning, followed by lunch at Fortune Centre and coffee at Mellower (hipster joint, I know).

Recrimped 1 x RJ45 cable and researched for a wireless mouse to replace the two I currently have. Both wireless mouse have scrolling problems (missed scrolls)

Just as I was about to hit Pay on the online website, a thought came across. Why don’t I try cleaning the scroll wheel on the mouse? So I gathered the tools:

  1. Screwdriver,
  2. Denatured Alcohol,
  3. Can of compressed air.

Opened up the mouse and removed the scroll wheel assembly. Surprisingly clean, despite it going places and more than 8 years old. (Dangling white connector – I’ve removed the two-wire connector from the base PCB)

Removed the scroll wheel and wiped the wheel slits clean. The slits triggers a counter in mouse programming to keep track on the number of clicks, thereby translating it to scrolls.

Did you note a possible JTAG header where the ribbon ends? 🙂

Cleaning the scroll wheel with Denatured alcohol on cotton buds and a few blast of compressed air helped to remove the minute debris stuck in-between the slits.

Note the white connectors from the outer shell connected back to the base PCB. A quick test after cleaning and saved another $40 under 10 minutes of work.

Very Naise.
