Trackpad screw getting loose often
I'm having quite annoying problem with trackpad of my Macbook white (late 2009 model). Screw which adjusts it's sensitivity is getting loose very often and thus my trackpad is not working anymore. It is still clickable, but click is not so crisp anymore and computer also doesn't respond to these clicks.
I found the instructions how to adjust the screw and it helps every time. But now i have come to point when i need to adjust this screw every week. That's way too much. Now im looking for a way to fix that.
Has anyone had similar problem? Any suggestions for solving it?
p.s. and i cant turn at the Apple service now, as I'm not living in my country where i bought it. last time when i had some problem, local service charged 100usd for just looking at the machine and concluding what was the problem..
Is this a good question?
