Keyboard
On my mousepath there is in left upper corner a small light - it stays on and no way to move the cursor anymore (I connect a separate mouse to work now)
Also the blue button for the wireless connection remains lighted, and I can't turn it off when working in the office with a plugged network cable.
What must I do ? How did I blocked the mousepath ?
Thanks for your answerKarine Van AckerMercuri International
