Here are our recommendations:
- Test the system on a minimal configuration out of the chassis and no memory installed. If the system beeps proceed to install just one memory module at the time.
- You can try a BIOS recovery test again and clear the CMOS battery with minimum memory installed but if the issue persists we recommend replacing the board under warranty.
Even more interesting... it does actually power on. The problem is, it takes so long that I'm not around when it does. Twice I've attempted to boot before heading out to work and it "fails" - the ME_STATE light slowly blinks but no fans kick on (probably watched it for at several minutes)... then when I'd get back ~10 hours later, wouldn't you know it - the thing is powered and booted.
Just confirmed it again.
Based on the uptime of my system, it took roughly 30 minutes after hitting the power button, for the system to actually power on. I checked it ~10 minutes after I hit the power button, and no dice, came back hours later to find it on (and the uptime would imply it about 30 minutes after I hit the power button).
I second that. Same problem - DQ77MK Power-On Failure. After system goes sleep state, impossible to power it again with power button. Green STDBY LED is lit. ME_STATE LED lights out (sometimes blinking based on what settings was set in ME) as soon as system hibernate with Intel Rapid Start feature.
I can power it back only unpluging-pluging power cord, but then all settings in Management Engine firmware is gone (reset to default) and POST reports: CMOS battery failure, CMOS crc error etc. I want to point out that BIOS doesn't loose settings. Thats strange.
I replaced battery - same behavior.
Motherboard have last firmware 0050, dated 08/30/2012
Any help would be great.
ATM this motherboard is totally unusable.
-Found that i can Power-On computer thru Intel System Defence utility v2.1.1 from power states:
a) S3 SLEEPING WITH MEMORY CONTEXT ONLY;
b) S5 soft off.
I RMA'ed my DQ77MK and finally got another one.
New one work as intended - without boot/Power-On/CMOS problems.
I'm having exactly the same problem. It looks like some part of those motherboards are just faulty. Main worked fine for about 1 day. I left my system powered on for a night and next day in the morning I realized that everything is down. Since that time i couldn't power it on at all. Today I RMA'ed my motherboard.
