Teknoids

Hi
Andy,
 
Yes,
this is certainly one of the weirdest laptop problems I have come across. There
are 3 sections of seats in the classroom. If you are facing the seats, it
happens in the left and middle sections. That is not exactly a pinpoint location
but is a general area I guess.
 
Thanks
for the radio idea. We will have to find one and give that a try. Have a good
weekend.

Touchpad Problem

Weird problem. Without being there, hard to tell what it might be.
Were they all in the same area of the classroom? That might pinpoint the
location.
 
One thing to try is to get your hands on a portable AM radio (not plugged
in - needs to be on batteries). Tune it between AM stations so you can hear
static. Walk around with it in the classroom and you can "hear" the noise as you
walk through areas of higher electromagnetic fields. You can even determine if
it's 60 hz by the constant cycled noise.
 
It's not the most scientific, but it's cheap and you can determine
locations of noise.
 
Hope this helps,
Andy

Hello
All,
 
During our final exams on
Wednesday, we began getting complaints from about 8-10 students that their
touchpads weren't working properly. If you moved the pointer around, it
would freeze every couple of seconds in one place for about a second and then
repeat the same action indefinitely. We brought in a few laptops from the IT
department and could not reproduce the problem. Additionally, we have never had
problems of this nature in this particular classroom before. We are speculating
that it is some sort of electromagnetic interference because if you walk out of
the classroom with one of the affected laptops, the problem goes away. There was
also no common thread with respect to the brand or model.
 
Any ideas or input would be
appreciated.
