Shutdown problem on Lenovo Ideapad Laptop

Here are Disk Management views from System 1 and System 2.
System 1 was installed from bootable USB.
Systems 2 (and 3) were installed from within System 1 using source files stored on U: drive.

Hi

right this is not my area, @jumanji @Megahertz07 @SIW2
hopefully these boys will follow up

do have 1 more question
Which option, (drive) do you select at startup C or D

The default option on the boot menu, Sys1, launches the Windows stored on the 100GB partition adjacent to the System Reserved partition. Windows marks this 100G partition as the C: drive.

I have my doubts this is a boot or hard drive issue. You can test my theory by removing the hard drive and running a Live disk of Hiren's Boot CD or Linux, then shut down. If the power light still stays on, you know damn well it's not your hard drive or its many logical drives.

This sounds hardware related to the motherboard or a BIOS configuration. Or perhaps you're using the wrong power adapter not meant for that laptop. Maybe even the battery is non OEM.

I don't see a motherboard that's cheap and merits the cost based on how much that laptop costs... "Lenovo Ideapad Z570" in All Categories - PicClick UK

I removed the Hard Disk and ran separate tests with 2 boot USBs.
(Hiren's Boot PE Windows 10 and PartedMagic Linux 6.2.0)
In each case a Restart behaved correctly, but Shutdown gave black screen with Power Light remaining on indefinitely.

The Power Adapter and Battery are both marked Lenovo.

On BIOS settings, do you have a Power tab?
Did you try to reset BIOS to default or re flash the BIOS with new or same version?

No, there is no 'Power' tab in BIOS settings.
I have reset the BIOS.
I also re-flashed (not updated) the BIOS from within Windows using download 45CN38WW.exe from Lenovo.
The problem behaviour remains, i.e. Shutdown gives black screen but Power light remains on indefinitely.

Any reason you didn't updated or there is no updated BIOS?

Is there any yellow alerts on Device Manager?
Did you install all the system applications to tour computer from the Lenovo site?

The BIOS was already at the latest version i.e. 45CN38WW, but I re-flashed it with download 45CN38www.exe from Lenovo support site.
There are no yellow alerts on Device Manager.
I believe all System applications are up to date. An 'Automatic Update scan' on the Lenovo support site shows 'no driver updates are required for your machine'

Thanks to guidance from this forum (esp F22 Simpilot) I have finally sorted out the Shutdown problem on my Lenovo Z570 Ideapad laptop.
The answer was to remove the CMOS/RTC battery for about 10 mins.
(I removed mains power lead, the large battery & finally the CMOS/RTC cell batt for about 5 mins.) Time needed to be reset)
I am not sure when/how the Sleep & Shutdown functions got messed up, but they are behaving now.
