My mouse (Logitech M705) and Sony keyboard lose connection with the computer for a second or so when typing. The cursor disappears from the screen for those few seconds and then returns. This occurs while using the Internet, using Word or Excel, and in other applications. When using the internet, I sometimes have to click the mouse to reconnect to the page in order to scroll.
This fault occurs usually after the computer has been in use for several hours. All batteries have been changed in mouse and keyboard.
Could anyone advise what may be wrong please?
