Problem resuming from sleep - NOT FIXED

[bononos]

I finally updated the mb bios along with a bunch of drivers and thought I might as well enable erp which I think might be the cause of the problem.

My problem now is that the pc doesn't resume from sleep if it goes to sleep by itself (lights are all on but won't resume after keypresses/mouse or pressing the power button), although it has no problems resuming if I send it to sleep directly using the start button->sleep (lights/hd will off/power down).

I've set it to sleep after x minutes, hybrid on, hibernate after x+y minutes. The bios/power settings are all correct. Has anyone came across this issue?

Edit:-
Not fixed. Its an intermittent problem and cannot always be reproduced. Its not fixed by setting the bios erp to off. The only workaround right now is to switch sleep off.

Tried to reproduce the problem by changing the sleep+hibernate time to 1/2 minutes and everything seems to be working fine....the pc resumes normally, hmm....

Edit: Problem occurred again. Its odd that I can't reproduce it by setting the sleep/hibernate timers to 1/2 minutes. I don't think its a problem with windows power management but probably some driver/service thing.

Check the Windows system and application logs to see if you have a service or application that hanging when the system tries to resume and fails. What are your system specs? Also, are you using an SSD? Sometimes they cause problems with sleep.

No ssd, no usb devices except for the mouse plugged in. Nothing out of the ordinary here, just an i3+z68 mb+win7. I've heard some older device drivers are incompatible with win7 sleep states and so I'll look through the logs. But I doubt I'm going to find anything because I have to soft reset to restart the pc.

My prior motherboard did exactly the same thing. It was a ASUS Rampage Extreme socket 775 board (at that time one of those fancy, outrageously expensive X48 based ROG boards that I never would have bought had I not gotten it on clearance for 1/3 of retail). It never worked properly with any form of sleep and always suffered memory corruption problems no matter what I tried -- the problem was BIOS related, and ASUS simply refused to (or more likely couldn't) fix the BIOS. I eventually just gave up altogether on getting sleep to work. When it finally blew out in September, I bought a new Sabertooth Z77 board which has no problems whatsoever with sleep.

Definitely make sure you are running the most recent BIOS as that can make a difference.

The problem started right after I changed the bios for better usb3 support and enabled erp at the same time as I said in the OP. The new bios supposedly cures sleep related issues which is all the more strange because I'm having that issue now.

Did you clear the CMOS memory and set the BIOS back to defaults after you flashed the upgrade? If so, it sounds like you've done all you can for now until they release a new one.

I Agree

I can't remember. I looked thru the advanced cpu settings and set a number of settings to enabled instead of auto (incl c3/c6 support). That fixed the problem. I can't remember if I forgot to reset the bios settings to default but I think I probably didn't. Thanks for the suggestion anyway, it was right on the money.

Edit- not fixed, see OP.
