Hey all, I am having problem with my old HP Pavilion dv4000. And the problem is that while I am typing something on my notebook at that time cursor moves randomly. For that reason only I canít be able to distinguish what I am typing. And here in this cause I am sure that I am not pressing anything else which can cause this type of the problem. Please suggest me that why I am getting that thing, suggest me any reason if you all having. And here I am using HP Pavilion dv4000, which is running on the Windows XP service pack 2.
