    Hello,

    My Sony VAIO (VPCEE33FX) is currently up and running. Here is the issue though. If it goes to sleep, hibernates, restarts, or any other function in which the screen powers down it won't come back on. For instance, I left my laptop for a bit and came back to it asleep I tried to wake it up and the screen stayed black even though the light on the power button was green and the fan was on. I then tries to restart with the same thing occurring (lights and fan on but the screen stays black). Occasionally if I keep restarting it it will come on like normal. In order to still use it I have disables sleep, hibernate, etc so that it won't go into a coma and never wake up. One weird thing I noted is that when I close the laptop even though sleep is disabled the lighting in the screen goes out but easily comes back on when I open it back up. This leads me to believe it isn't a backlight issue. I don't know a whole lot about computers, but maybe it is the screen inverter? Anyways, if anyone could give me any auggestions I would really appreciate it! It is very frustrating having to keep it plugged in on life support 24/7 without being able to shut down or restart. This thing is only 1 year and 2 months old (just out of warranty....). Thank you all in advance for your generosity in helping me with this.

    Welcome to PCHelpForum.

    Give us a better chance. Use following procedure to complete your system specs.

    Don't shoot me. I know that this needs to be cleaned up, however, perhaps this will help in the meantime.

    POWERCFG COMMANDS

    To output a list of system devices that support wake from sleep mode
    powercfg –devicequery wake_from_any

    The ability to recover from sleep mode is typically a feature of the hardware driver.

    Example:
    C:\>powercfg -devicequery wake_from_any
    Standard Enhanced PCI to USB Host Controller
    PCI standard PCI-to-PCI bridge (001)

    rc,

    Boot into the bios and make sure that there isn't a setting there preventing you from coming out of sleep with either the keyboard or a mouse.

    I ran across this problem once that a bios had a setting that was messing things up.

    WIN | type DEVMGMT.MSC | expand Keyboards |
    right-click on HID Keyboard Device | choose Properties |
    Power Management tab |
    make sure that "allow the computer to turn off this device to save power" is NOT checked
    make sure that "Allow the device to wake the computer" is checked.
    OK button

    Do same thing for any "Mice and other pointing devices"

    Not all devices will show a power management tab.

    Sorry about the misunderstanding.

    After you boot into Windows,
    then :
    1. tap the WIN key (that's the one with the wavy microsoft flag on top)
    2. type DEVMGMT.MSC
    3. in the resulting display, expand the Keyboards item.

    and so on and so forth.

    Thanks for clarifying. There was no power management tab but there was a detail tab where I could select power data. It came up with something that looked like this:

    Current power state:
    D0

    Power capabilities:
    00000009
    PDCAP_D0_SUPPORTED
    PDCAP_D3_SUPPORTED

    Power state mappings:
    S0 -> D0
    S1 -> D3
    S2 -> Unspecified
    S3 -> D3
    S4 -> D3
    S5 -> D3

    I fixed it! I decided to go into the bowels of my laptop and make sure everthing was securely connected. I did two things in there and one of them was the solution. I disconnected and reconnected where the power and other wires run from the screen into the main board. I removed and reinserted the top RAM card. Not sure which fixed it but the issue is gone! Thank you guys for your support as it was the only reason I kept going (I would have caved and gone to Geek Squad if no one had responded on this forum). Glad I didn't have to pay someone $300 just to fix that.

    THANK YOU!

    RC,
    Glad to hear that you have fixed the problem and thanks for getting back to us with how.

    I'll have the thread marked as closed.

    With the savings from the money you would have paid out to the Sgueck Squad, then I'm sure that the management here would not be opposed to a token appreciation donation to the forum.
