I got a new motherboard that has a couple of energy saving features that are starting to worry me. EuP jumpers for sound and NIC. I left them in the enabled setting, since my new PSU is EuP certified anyway...Couldn't hurt, right? Energy here is getting pricy and when I'm not using the computer, I like to leave in stand by. Here's the problem, the computer won't resume from stand by/sleep, which I assume is S3, since Suspend to RAM on the BIOS is on...but wasn't with the default settings (great job, ASRock! ). I press a key on the keyboard, 320Gb and 500Gb HDDs power-up, 1Tb one takes its time, but no image. Monitor stays in stand by mode. I've been roaming the internet to find issues related to these power saving features, but there's a plain lack of information about it overall. That and "check ready bit", which I only know it is a good idea to turn off if you have an SSD...not my case. Any input, gents? EDIT: I've tried with the jumper off, but I couldn't get conclusive results. I tried a 30 second stand by period and the computer woke up, longer than that, about 10 minutes and it didn't.
