Long Black Screen before Boot Solved

    Long Black Screen before Boot


    At some point in the past month or so, my laptop has started taking a much longer time to boot. Specifically, I get a black screen that lasts for anywhere from 10-15 seconds before the boot logo even shows up. I'm pretty sure the screen isn't actually even on while this is happening. At first I thought it was something to do with my GPU drivers, so I uninstalled them and tried booting again, but the exact same thing happened. My laptop hasn't always been like this. It used to boot completely normally, with the boot logo showing up right after I hit the power button. I have an SSD, so it doesn't take long at all once the screen actually shows up. Can someone help me troubleshoot this? I filled out my laptop's information in my profile, but if there's any other information I can provide, please let me know.

    Hi Kurausukun. Welcome to the TenForums @Kurausukun

    Is this long black screen visible when you restart or when you power up or both?

    When you uninstalled you GPU drivers did you delete software and then load the most recent driver from Nvidia?

    What build are you on? Windows key + R, type winver, enter.

    If you look at windows update history, at the bottom it list drivers it updated, were your Nvidia drivers updated? Any other drivers in last month.?

    Winver tells me I'm on version 1709, build 16299.371.

    The black screen actually doesn't happen if I just restart, it's only when powering on from a full power off. Also, it doesn't seem to happen when I force shutdown the computer by holding the power button.

    When I uninstalled my graphics drivers, I did exactly what you described--I made sure everything was uninstalled, tried booting, and when it didn't do anything, I reinstalled the latest drivers.

    Windows update doesn't list any graphics driver updates (which makes sense, I install my graphics drivers manually). The only other things that were updated in the past few months were my trackpad driver and what I believe to be either my NIC or Bluetooth adapter (it just says Qualcomm Atheros Communications Inc. - Net).

    Thanks for the help.

    Sound like it is related to Windows Fast Startup. I would first recommend trying to shut it off.

    Turn On or Off Fast Startup in Windows 10

    If that doesn't work you can try disabling hibernation.

    To a command prompt(admin) or powershell(admin)

    powercfg -h off

    To enable change the off to on

    Thanks a lot for the advice--I've worked out the problem. A while back I turned off hibernation using powercfg because I didn't want a 16GB file sitting around my hard drive, but I didn't know that fast startup used hibernate. Now that I've turned hibernate back on, Windows is back to booting quickly again. Thanks for the help.
