Windows 10: Fast startup causing my laptop to turn on after being shutdown

my laptop was working fine until suddenly, when fast startup is on, whenever i click shut down, my laptop, after shutting down, automatically boots right back up? how to fix this issue?

:)

 

My computer cannot shutdown with fast startup turned on

My computer cannot shutdown with fast startup turned on.After I click the button,it just goes to the lock screen.But I can use "shutdown -s" to shutdown successfully. This has also caused other problems.For example,I can't join the Windows Insider Program.All
these problems vanish if I turn off fast startup.

 

I have turned off fast startup and sleep mode

I recently upgraded my laptop to Windows 10, and now it won't shutdown properly.

I have turned off fast startup and sleep mode from power options.

Here is what happens:

• Start menu > Power > Shut down
• It exits windows and apparently turns off (black screen)
• The power lights are still on and my computer apparently doesn't shutdown.

 

Abnormal shutdowns with Fast Startup enabled

Hello - I recently (18/6/2018) set up a new laptop(Dell Vostro 5370) which for the most part is running well, but Reliability History shows frequent "Windows was not properly shut down" events, which a sleep study report from powercfg shows are associated
with transitions into what the sleep study labels as "Shutdown (hybrid)". There are corresponding critical Kernel-Power event ID41 entries in Event Viewer. Turning off Fast Startup seems to work round the issue, but it would be good not to have to do this.
As well as updating everything in sight I have tried the usual checks with DISM and sfc, and run the hardware checks in Dell's SupportAssist, but they show no problem. I have also run the Boot Performance (Fast Startup) assessment in the Windows Assessment
Toolkit, but this just reports that it cannot complete the assessment owing to a system crash. Can anyone suggest any other troubleshooting steps, or remedies? Thanks...
