hp n5450 laptop problem

[Anoosh Abdy]

I have an HP n5450 laptop with redhat 7.1 installed. The laptop
constantly freezes and the only
way to get any response is to turn off the pc which has led to loss of
data and several OS
reinstalls.
I think the problem is with the touch pad sesitivity. Once the pointer
is on any control
(such as buttons, menu item, etc) for longer than 5 seconds the control
is automatically
operated on. I searched for touchpad driver and found tpconfig, but it
does a core dump when
it is run. Does any body know what the problem is. I tried both
KDE/sawfish and
Gnome/sawfish with no difference. tpconfig is unsupported. I contacted
redhat by they don't
support touch pad neither they could offer any help for the freeze
problem.
I'm sending the email through my windows NT machicne and have edited
pref.js, lipref.js. I hope it removes the header.
