Optical mouse shines continuously even when the PC is switched off
Some motherboards like Arocks enjoy great popularity amongst those who want ot upgrade, but are willing to spend relatively less. However, after the modification, the optical mouse glows even when the PC is switched off.
This happens with some other motherboards also. The cause of this strange occurrence is an uncommon jumper put on the main board, which is responsible for the powering of the USB buses. This provide the USB bus with the standby power (+5VSB) to enable the switching ‘ON’ of the computer via USB or PS2 devices. Connected devices were continuously supplied with electricity in this way.
If you change the position of the jumper from its 2/3 original position to the ½ pins, everything functions as usual and in a stable way. Note: Change the above jumper configuration only when the computer power cord is unplugged.

Finally double click and open the ‘Security options’ in the ‘Local Policies’ tree. Select ‘Network security LAN Manger Authentication level’ in the list that is displayed next.
