Mice and Electro-Magnetic Interference

[Dennis]

Hi

My wireless desktop mouse just had an interesting encounter with the effects of EMI/EMC (Electro-Magnetic Interference/ Electro-Magnetic Compatibility) from my notebook computer AC adapter.

Symptoms:
The cursor of my wireless mouse suddenly slewed to a crawl and responded erratically to physical movements of the mouse.

Cause:
I had just attached my notebook computer to the router and placed the notebook mains adapter in line of sight between the desktop wireless mouse and the mouse docking station.

Cure:
Move the notebook mains adapter some 12” away, not in line of sight and normal behaviour of wireless mouse restored.

Cheers

Dennis

PS – In the mouse installation guide, it does mention avoiding placing the mouse near radiating sources.

Thanks for the heads-up Dennis.

When this happened, my hypersensitivity to Trojans, malware etc. made me hit the modem standby button to kill the broadband connection, before I realised what the real cause was!

Phew!
