The subject of this thread is not about what it turned to be, but anyway...
I must say I read somewhere once (don't remember where) about the
problem with the fingerprint device getting to hot, but it was fixed on
on of the updates.
Now, I have noticed that some (very occasional) times the fingerprint
gets very hot, like if it was not turned of after login or something.
So I was wondering if there is for a certain process one could check
(with ps) and kill or any command one could issue to turn the device off.
Cheers!

<pre wrap=""><!---->Just as a confirmation. On my T43, with the proprietary finger print
driver, the reader is not on all the time and the finger print spot is
not hot compared to other points. On my T43, the finger print reader is
right above hard drive, so if it gets hot, not only it wastes power but
it also harms the hard drive!
