Dear Christopher,
I have now upgraded my X250 bios to version 1.17. I downloaded the bios from
Lenovo
NIOET38W (1.17)
and installed it on my X250.
I then verified the the old bios (1.15) had been upgraded to 1.17.
I did this by booting into the bios, and checking the version number.
I then again verified the installed bios version and release data:
sudo dmidecode -s bios-version
N10ET38W (1.17)
sudo dmidecode -s bios-release-date
08/20/2015
I then rebooted my X250, and verified that the bug of the mouse-button click
(bug 1506817)
is not fixed by updating the BIOS.
So the problem remains active.
Summary:
The bios is updated and verified, and the mouse bug is still present and
Confirmed

Title:
left TPP/2 IBM TrackPoint "sticks on" randomly (X250 15.04)
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have reported the details of this problem at
https://answers.launchpad.net/ubuntu-certification/+question/272142
As summarized on that question:
X250 analysis:
I used the command on the X250
evtest /dev/input/event15 | grep EV_KEY
I can see the bug, as follows:
I click on button 1 (left) over and over. When I push the button down,
I see it register as 1,
and when I let go of the key, it registers as a 0.
The bug is that every now and then (once every 20 clicks), when I let go
of the left mouse button (BIN_LEFT), it does not return to state 0 (it stays
in state 1).
This is highly random, but cant be triggered more often, by dragging a
window, which I do with BIN_LEFT.
I am using a brand new X250, purchased in late July 2015. The system was
returned 3 times to IBM repair as I assumed
this was a hardware error. Now with the above, it seems clear that this is a
software issue.
