    Cannot wakeup from sleep; reboots


    Hi there. Trying to figure out a problem. Running Win 8 Pro, 64bit.
    I recently installed an upgrade of my BIOS. At first it took several tries to boot into Windows. That is now solved. What remains is the fact that when I wakeup the system from sleep, it only displays the pre-login screen (greenish, with the tower). It freezes right there. Thinking this might be a display driver issue, I updated it (Radeon HD 6480G). That didn't fix the problem. On some forum I read about a SAM file. My question is: How does it find it when I reboot, but not when the system goes from sleep to wake up? At any rate, how could that be fixed? Also, I don't know how to revert back to a former version of my BIOS. Have no idea where to find that info. My laptop has an Insyde board, and it went to version F.48, what ever that means. Thanks in advance for your ideas.

    My possible fix probably won't sound reasonable (and it might not be). But, try turning fast startup off.

    Thanks, znod. I did turn off the fast startup. Ironic, because it's been taking more time to boot/start up. Also, I do have a recent system backup disk. I do this regularly. How will that help? Should I restore the system using it?

    You said you updated the bios. Often, you can opt to keep the settings. Sometimes this can make it flaky. resting the bios to defaults may help. Also it could be a bug introduced by the new bios. If it was good before, maybe flashing back to the original bios might help.

    I actually reinstalled the last BIOS update, from several months ago. I performed a system restore. Everything works fine. Thank you all for the help and suggestions.
