MaLa Hardware - Power When Shutdown

  • I have one of those motherboards that does not give you the option of turning off the +5V to the USB ports when in standby mode. (K7 Triton GA-7N400).


    This results in the LED's and LCD being fully lit when PC in standby. X(


    One solution is to hook up a relay so that usb power is only connected to the MaLa hardware when the PC is ON. I want to avoid the hassle of this if possible.


    Has anyone got any suggestions for a possible solution?


    Thanks

  • I will do that for you late next week. :-)


    By the way. I found this problem particularly frustrating as my other two PC motherboards do allow you to turn off 5V standby power to the USB ports using a dip switch on the motherboard. But I am not about to swap them as they are motherboards for P4 and my Mame table has a slower AMD chip.

    If I plug my MaLa Hardware into a Powered USB Hub and
    1) I obtain Power for the Hub from a Hard Drive Plug
    2) Disconnect the Power wire inside that Hub coming from the motherboard


    ..Then in Theory it will only get power when the PC is fully on.


    I'm going away (camping) for a few days, But I will test this idea out late next week.


    It may be a simpler alternative than hooking up relays.


    mmmm still thinking :rolleyes:

    Forget that idea. Back to the drawing board. The Hub will not fuction without 5v coming from the motherboard, even though the Hub is self powered. ??? Very Strange


    Not Happy X(


    ...Anyway I will post my original Relay plan here when I have made it.

    hi loadman,


    would be nice if you could post your solution here, when its done. As Arnulf i have the same issue with the usb...


    I've decided I will leave it as is. The LED's will remind me to turn off the machine properly. Even if I forget, they use minimal power.


    If anyone is still interested in a 'simple relay solution' let me know and I will draw up a diagram. It would just involve hooking up the 12v magnet side of the relay to a hard-drive type power plug, and the switch part of the relay on the 5V betwen the LED and USB plug.


    Cheers...Merry Xmas....
