Title: Problem with ErP Support
Post by: PJay on March 12, 2012, 08:30:33 pm

When I enable "ErP Support", my Creative SB Audigy doesn't work after sleep.
Any solution?  ???

GA-H61M-USB3-B3 (rev. 2.0)

Are you using the latest BIOS?  If not updating may help.

Otherwise don't use ErP as it may not provide enough power during sleep, that could be due to how it's configured or your PSU

Yes.

If I disable ErP, it doesn't turn off the usb power while shutdown :(

That is a feature of most modern power supplies, so you can charge your phone, ect with USB.

You can try hidden setting to disable wake via USB.   On the MAIN page of the BIOS, press control + F1, the screen will flash, then go into power page and disable wake via USB and save/apply and see if that shuts off USB with the board.   If not, it's because your power supply is modern, motherboard and power supply manufacturers see this as a "Feature"

Ya, most new power supplies wont allow it, due to always having positive voltage on the +5VSB rail, and boards keep this going to charge things via USB.   You can try to request a special BIOS with the +5VSB line disabled, they might make one for you, worth a try asking

Ahh ok, well if you need it disabled you'll have to request a special BIOS or find an old PSU that doesn't support it.
