Picked up Microsoft USB receiver, wireless keyboard & mouse at a garage sale. Testing them the keyboard was unresponsive
Symptoms: #
- USB receiver LED on
- Receiver flashes on button press
- Mouse connects (pair button mouse, pair button receiver)
- No visible LED on keyboard
- Keyboard does not connect (pair button keyboard, pair button receiver)
Notes: #
- Used new batteries
- No multimeter on hand
- suspect damaged antenna or damaged power wire
Troubleshooting steps: #
- Checked mouse pairing & responsiveness
- Opened keyboard housing
- Checked power wire visually for opens, shorts
- Reseated power cable in white plastic connector
- Cleaned contacts, receiver button with isopropyl on q-tip
Next steps: #
- Multimeter test: power wire continuity, power across connect button
Searched and reviewed documentation online. Found the manual for keyboard. My keyboard model does not match the wireless receiver. Likely not worthwhile correcting.
