[lubuntu-devel] lenovo_wmi or acer_wmi driver for Lenovo laptops (64 bit)?

[Richard H. McCullough]

I have two Lenovo ideapad laptops: Lenovo 3000 N200 with 4GB RAM and Lenovo Z570 with 8GB RAM. 
I am currently dual booting Z570 with Lubuntu 16.04.3 and Windows 10 Pro 1709 Insider Preview. 
As soon as my N200 is repaired, I plan to dual boot with Lubuntu 16.04.3 and Windows 8.1 Pro. 
(I gave up on Windows 10 because it runs very slow with only 4GB RAM).

Off and on, I get this error on Z570 

acer_wmi: Unsupported machine has AMW0_GUID1, unable to load

1) My initial Lubuntu install with msdos partitions and no EFI System partition failed with this error.
2) My second Lubuntu install (after re-installing Windows) with GPT partitions including  EFI System succeeded.
But after two (or three?) automatic "Software Updater" sessions, it again failed with this error.
A confusing factor is that Windows Insider Preview kept resetting my clock to London time (I'm in Los Angeles time zone).
This broke Cygwin make command, and forced me to re-install Cygwin.

According to Torvalds GitHub source for acer_wmi.c, N200 is on a quirks list of machines that is allowed to use Acer driver.
Z570 is not on the list, and Torvalds asks that no more Lenovo machines be added to the list.
So I need to know:
Is there a lenovo_wmi driver?
Was Z570 added to quirks list? If so, is it still on the quirks list?
