    RAM(virtual memory) settings have some part to play in this. Thinking too small of a setting may upset the ability to return computer(wake from sleep) to last known state.

    So I created an account just to answer this, and hopefully this easy solution will help a few of you out. I was having the same problem with Windows 7, sometimes when I would put my asus laptop to sleep and try to wake it up later, only the cpu would wake up, but not the monitor. At the time I would close and reopen the lid and the screen would come on, and it was a tad annoying but tolerable. Once I upgraded to Windows 10 it was all the time, sleep but no screen wake up, and closing and opening the lid did nothing at all. I had to shut it down completely and boot back up. I don't like to leave my computer running non-stop, and I came here and saw many others with the same problem.

    I tried an easy solution, and it works fine. I changed the power settings to hibernate the computer when I press the power button, and so when I press the power button again, it wakes from hibernation quickly, and the screen comes on with it. I know some here just maybe want to turn the screen off, and on a laptop you already have a function key for that. But I don't want to be using electricity all day with my computer running with the screen off. Sometimes the running cpu actually affects my antenna tv, a couple channels, but now that I can hibernate and wake it quickly and easily, I've solved all my problems.

    I hope this helps. It's an older asus, a42jz, and I just timed it, 20 seconds to wake up from hibernation. I'm perfectly okay with that.

    Not a computer whiz but I had the same problem. Computer wouldn't wake up. Black monitor screen, sometimes would flash once. Could get computer to turn on sometimes with after turning power button on and off. Tried all the suggestions. Finally, replaced the monitor with an old one I had. Viola. Problem was the monitor all the time. Computer was waking up fine. Sometimes it's something simple. Check all the hardware, too. Learned my lesson, believe the little blinking LED lights. Thanks.
    I have a desk top.

    Glad this helped. I'm still working w my band aid solution, which is disabling anything happening when cover is closed, and either manually putting laptop to sleep or shutting down when not in use.

    I have this problem. When the computer stays suspended for too long it then won't wake up by simply pressing on the mouse and have to click on the laptop's power on button.

    This didn't used to be an issue before but after reinstalling Windows 10 fresh is. Aside this, it works perfectly.

    I have the same problem. Simplest solution for me is to unplug the monitor, let the orange light go out and plug it back in.

    That would be a little tough to do on Saiyan90's Laptop/Notebook.
