After the (forced) update, my laptop shuts down when closing the lid or timing out even though the battery settings are set to sleep

I have searched a ton of articles and have made sure that the settings are set to sleep, I've turned off fast start/restart, and my computer continues to shut down. I uninstalled the updates and that allowed my computer to sleep when timing out/closing lid for a little bit but then my laptop was force restarted and the updates were reinstalled. I have not been able to resolve this issue and it's extremely frustrating

    Since the lid-close and timeout actions are already set to Sleep and disabling Fast Startup did not hold, the most relevant next checks are:

    1. In Control Panel > Power Options > Choose what closing the lid does, confirm both On battery and Plugged in are set to Sleep.
    2. In the same area, select Change settings that are currently unavailable and verify Turn on fast startup remains cleared.
    3. Use Restart, not Shut down, after changing power settings. Windows restart performs a full boot cycle, while Fast Startup affects shutdown behavior and can interfere with update completion.
    4. Install all available updates, including optional firmware updates for Surface, from Settings > Windows Update.
    5. In an elevated Terminal, run: 
         powercfg /a
      This shows whether Sleep states are available on the device.
    6. If the system still fails to sleep correctly, Fast Startup can cause shutdown or hibernation-related failures even when the expected behavior is sleep. A full shutdown test can help isolate that behavior: 
         Shutdown /s /t 0
      This performs a full shutdown.

    If the symptom is specifically that shutdown or hibernation fails and returns to the lock screen, Microsoft documents checking Event ID 45 in the System log and then verifying the DumpFilters registry value under:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl\

    Important: registry changes are risky. Incorrect edits can cause serious system problems. If that event is present, the documented value is that dumpfve.sys should be the only entry in DumpFilters, followed by a restart.

    Also relevant for update behavior: some Windows updates are completed only after a full shutdown/start cycle. With Fast Startup enabled, shutdown uses hibernation instead of a full shutdown, which can delay update completion. In that case, Restart is the correct choice to complete pending updates.

    Hi Debbie T,

    Since the issue temporarily cleared after uninstalling the update and then returned when the update was reinstalled, it may be worth checking whether Windows is recording an unexpected power transition rather than a normal sleep event. Based on your description, the standard power-setting checks have already been covered.

    As a next step, please try:

    1. Open Event Viewer > Windows Logs > System.
    2. Close the lid or wait for the timeout to occur.
    3. After restarting, look for Kernel-Power, Kernel-Boot, or Power-Troubleshooter events at the exact time the shutdown happened.
    4. Note any Event IDs or error details that appear consistently.

    You can also run the following command in an elevated Command Prompt after the problem occurs: powercfg /sleepstudy

    This generates a report showing whether the device attempted to enter sleep and what prevented or redirected that transition. Those results can help determine whether the behavior is being triggered by a driver, firmware component, or a power-state change rather than the configured sleep settings themselves.
