[Hans Deragon <hans@xxxxxxxxxxx>]

My Lenovo T61 died on Sunday evening.  Does not even boot to BIOS, no
beep; it is a brick now.  Got myself a Lenovo w510.  Took the drive from
my T61 and put it into my w510.  The stock kernel 3.14 also does not
work with the w510 and proprietary Nvidia drivers.  I never had the
chance to update the BIOS of my T61.

I have no clue if the w510 suffer from the same problem.  Do we leave
this bug open in case someone else suffers from it?
