Seller CYA. Many Lenovo laptops have BIOS whitelist.

Can you tell how to go with the process?

You will need to learn about ACPI.
A good place to start is to read the ACPI specification.

Two questions on installing kexts:

(1) For 10.11+, kexts can be installed by just issuing these two commands back-to-back?

sudo cp -R /path/to/kextToInstall.kext  /Library/Extensions/
sudo kextcache -i /

(2) Are there some kexts that when installed to /Library/Extensions/ show up in the list of files and directories there as "Contents" rather than as, say, AwesomeKext.kext? Or does seeing "Contents" in the listing indicate that the kext was not installed correctly?

sudo cp -R /path/to/kextToInstall.kext  /Library/Extensions/
sudo kextcache -i /

First is to install kext.
Second is to rebuild cache.

(2) Are there some kexts that when installed to /Library/Extensions/ show up in the list of files and directories there as "Contents" rather than as, say, AwesomeKext.kext? Or does seeing "Contents" in the listing indicate that the kext was not installed correctly?

If you have a question regarding kextcache output, you would need to attach the output here.

I am trying to install ACPIBatteryManagerKext.kext. It appears in /Libary/Extensions/ as "Contents".

You installed it incorrectly.
Now you need to remove that Contents directory:

sudo rm -rf /Library/Extensions/Contents

Then install correctly:

sudo cp -R /Users/Home/Desktop/HighSierraHelperFiles/ACPIBatteryManager.kext /Library/Extensions

There is much difference between (this, wrong):

sudo cp -R /Users/Home/Desktop/HighSierraHelperFiles/ACPIBatteryManager.kext/ /Library/Extensions

... and (this, correct):

sudo cp -R /Users/Home/Desktop/HighSierraHelperFiles/ACPIBatteryManager.kext /Library/Extensions

Read 'man cp' for more information.

I didn't even notice. I was just using Tab-autocomplete.
Thanks. That fixed several problems.
