hello, also having this problem with the ThinkBook 15.
The touchpad seems to be of type "ELAN062F". I see this is also the same
as listed in OP's udevdb.
It seems that this could be the fix, since the ID "ELAN062F" is not present in
the whitelist in "include/linux/input/elan-i2c-ids.h":
The same issue on the ThinkBook 15 IML, running 18.04.
Also, there are another issue with finger login, I can`t use it.

Same issue on ThinkBook 14 IML, running Ubuntu 18.04.
A quick test with Manjaro 18.1.3 showed the same issue.

There's no BIOS update on Lenovo's site, only a comment that it has been
pulled.
'sudo acpidump' output attached.

Could you try to upgrade BIOS?
If it is still not working please upload the results of "sudo acpidump"
and dmesg.

Similar issue here on ThinkBook 15 IML, running 18.04.
Tried booting with kernel parameter "i8042.nopnp=1" but made no
difference.
