First things first.<br>
Make sure your ISO image is correct using md5sum.<br>
Personally I like using zsync to download an ISO because it
automatically checks the md5sum and makes sure things are correct.<br>
If the image is flawed re-download it and check it (or use zsync
with the current image, as it should update the image and fix it and
save you downloading time)<br>

This command will list all kernel modules with wmi in their name:<br>
find /lib/modules/$(uname -r) -type f -name '*.ko*' |grep wmi<br>
For me I fine and acer_wmi, which is probably the one your computer
is trying to load<br>
You might need to blacklist it, and load a different module instead,
or if it isn't being loaded properly (being blacklisted) you might
need to force it to be loaded.<br>

This may be a different issue altogether, but I think verifying the

It may be due to your hardware clock being incorrect. You might
need to ensure your hardware clock is right. Windows might assume
it is, and Lubuntu may not be assuming it. So if your cmos battery
is low, it might be reseting your hwclock to Ubuntu time (Canonical
has an office in London and is located there)<br>

I am not sure of that I have a Lenovo, and do not see any lenovo
specific kernel modules, however when I search my modules I find:<br>
/lib/modules/$(uname -r)/kernel/drivers/hid/hid-lenovo.ko<br>
<br>
I subsituted $(uname -r) because your kernel will be different from
mine<br>

Some people have gotten it to work well.<br>
<br>
You might try a live CD from an earlier release (14.04) to see if it
performs well, and if you have time to try things out, you could
install it to see if it is working.<br>
<br>
If things work, you could check the modules that are loaded for the
working kernel, with this command:<br>
lsmod<br>
<br>
And then use those modules in 16.04<br>
