LCD still backlit if I shutdown PC. My PC has permanent power +5 V into all USB ports, even if PC is shutdown. In BIOS nothing to change it. I made small improvement today. I used 2x USB bracket this type:
and cut off one RED wire. Then I connect this into one free HDD Molex connector (RED wire) from power supply.
If is PC off, then +5 V to lcd panel off. If I power on PC, is panel powered too.
Is possible use 4x USB bracket and cut off all red wires and direct connect into +5 V Molex, for more USB accessories.
