I feel that your t43 becomes (too) old.
During the warranty of my t42, IBM changes first the fan, and one year
later the mother-board because the display had fuzzy errors. Now the
cd-writer is almost(?) broken, but the warranty is out of date.
Twice IBM takes the laptop without the hard drive. I keep it.
Twice I test my laptop in order to describe not a fuzzy brakedown but a
real and obvious brakedown. I keep and use the window partition only for
theses tests.
