    Default Can't Wake Up Computer

    Hi All,

    After accomplishing some very mild overclocking of my i7-920/Megabyte UD5P I am having trouble regaining control of the computer after it goes into "Power Save" (I'm not sure of the correct technical term).

    When I leave the computer for a few minutes it switches to screen saver. I can still regain control by clicking/moving the mouse. If after the screen saver mode, it is left longer it goes into a "power save" mode where it appears to shut down the computer (no lights on the computer and nothing on the monitor screen). In the past I could always wake it up by clicking the mouse. Now when I click on the mouse the lights come on in the computer, but nothing shows up on the monitor and I lose control to all USB peripherals. The only way I can regain control is by unplugging the main power cord and plugging it back in.

    During the OC I did have to clear the CMOS one time and reload Optimized Defaults. The following are the settings on the BIOS Power Management page:

    ACIP Suspend Type S3(STR)
    Soft Off Power Button Instant Off
    PME Event Wakeup Enabled
    Power On by Ring Enabled
    Resume by Alarm Disabled
    HPET Support Enabled
    HPET Mode 32-bit model
    Power on by Mouse Double Click
    Power on by Keyboard Disabled
    AC Back Function Soft Off

    The only thing I can see that might be out of line is the fact my system is 64 bit.

    Any suggestions??

    Thanks - Thud

    To resume from S3 sleep, what you are using and describing, your system must be 100% tested stable and you must be using the latest BIOS.

    What BIOS are you using for starters, if it is older you will need to update before you try further to get this working.

    If you are just unsure how to disable this function and do not want to use it, let me know what OS you are using and I can tell you how to disable Sleep altogether

    Thanks to both of you for the responses.

    I have only had the computer I'm using for a couple months. My OS is Vista and the BIOS info is x58-UD5 F7 Award BIOS v6.00PG with a string 5/11/09 X58-ICH10-7AB89QG05C-00

    After reading the dire warnings and the extensive procedures involved, I am very reluctant to flash the BIOS.

    What I don't understand is the function worked with the current BIOS before I messed with the CMOS - no other changes - and now with the optimized defaults + minor changes for OCing it doesn't. Seems that one of those changes must be resulting in the fact that when the computer enters the sleep mode, I lose control of the USB peripherals. Is there not some CMOS entry that can be changed back?

    Thanks again - Thud

    Listen to these Gentleman. Update the BIOS . I have been through several systems with the same problem of the system going into a coma. All those warnings are more like disclaimers and i can most guarantee a bios update will fix this. As the above say, just be sure to do it correctly.
