  1. PC always takes a long time to wake up from sleep; common purple/green screen


    My computer takes forever to wake up from sleep since I've moved to my new apartment. Shortly after I upgraded my monitor, but the problem didn’t get much better. After it wakes up, it will often not show the login screen, just the background for it. The weird thing is that it stilll responds to typing, and if I enter my pin correctly, it will unlock.

    To put things in perspective, I have an NVME drive as my boot SSD and I have no idea why it takes so long for my computer to properly talk to my monitor.

    To make things worse, after the latest May Update for Windows, my screen is often completely green or purple, and this can only be resolved by rebooting. In the midsts of all these problems, I also got a new graphics card, and I used DDU and none of the problems changed.

    Please help.

    Troubleshooting PCs spontaneously waking from sleep

    I've also battled with sleep/wake issues over the years, and from experience have learned that trying to find, or rationalise, the root cause is a waste of time. All you need is `powercfg`.

    `powercfg -devicequery wake_armed` from an Administrator PowerShell window/Command Prompt will give you a list of all devices that can possibly wake the PC. This command is interesting because very often, it will show devices that you'd never expect being able to wake your computer. I think in one instance I had the chipset device listed!

    `powercfg -devicedisablewake "device_name_from_device_query"`will prevent said device from ever waking the computer. This command is 100% the only thing I have found that will resolve sleep/wake problems. Updating drivers, unplugging peripherals, switching to a cleaner power supply (UPS), changing ethernet cables... none of those have helped, yet`powercfg -devicedisablewake` has done the trick.

    Note that occasionally, devices you have disabled wake for may start waking up the PC again - this happens if you plug a USB device into a different port, or occasionally when drivers are updated, because Windows sees it as a new device. In that case rerun `powercfg` to find and disable that device again.

    If this does not resolve your wake issues, I would start looking at power fluctuations.
