Hello,
My daughter has been using a T30 2Ghz machine for school the last three
years. The screen has started to display a wavy, static-like picture after
about 30 - 45 minutes of use. If the machine is turned off then immediately
turned back on the static remains. If the machine remains off for a few hours it
takes the 30 - 45 minutes for the problem to reoccur. I checked to make
sure the fan was still running and it is. I searched the group archives and
could not find a similar issue. Any suggestions as to what might be causing the
problem? Is it worth repairing? Thanks!
Hello Mike:
If I understand you correctly, the distortion of the
image on the display starts out with little fibrous
looking extensions from the edges of objects on the
screen and eventually reaches the point where the
whole screen appears to almost be scratched both
horizontally and vertically to the point that the
image on the screen is virtually unusable. Have you
tried using a little pressure along the edge of the
palmrest area? If it steadies the image to normal,
or virtually normal, I've seen this with two T30s.
If not, I'm not certain that I can be of much help.
The interesting thing is that both T30s work(ed)
perfectly when attached to a docking station. In
fact, I'm typing on one of the T30s right now. The
first time I encountered this problem was when I was
flying to the town where I grew up in terrible
weather to attend my mother's funeral. The airline
used a smaller local-style plane (out of Chicago)
and forced me to reliquish my laptop bag. My best
guess is that it was compressed sharply, damaging
the ribbon cable from the motherboard to the display.
I purchased a replacement ribbon cable as well as a
second T30 (as a backup to which I moved the hard
drive from the first T30) but, after moving to a new
office building do not believe I've ever seen the
first T30. I may have moved it into a pile of stuff
that I've never sorted since the move but fear that
it was discarded mistakenly by someone else. For
this reason I have never had the opportunity to test
my hypothesis about the cable.
BTW, I realize that it's odd that it works pretty
well until it begins to warm up, an argument against
a simple cable problem.
I'm preparing to copy the hard drive from the second
T30 to a T42 or T43p when I get a chance. After that
I can see disassembling the T30. The T30 is a sturdy
machine. Mine have weathered significant abuse and
have developed no other problems. For this reason I
plan to repair mine. I even bought a DVD-RW drive to
install in it to make the copying of hard drive data
a little easier.
(I suspect this was "too much information" of which
too little was useful.)
I hope this is of some help to you.
