I am surprised that you are not aware that there is a dedicated user forum for you model -- zd7000forums.com
If you go there and join the forums and post the question in the relevant section (technical support or similar) then you should get an immediate and detailed response from another user of that notebook.
I get help like this all the time for my notebook at the similar X1000forums.com
If you did a google search for zd7000 you would have found this forum yourself (or any other decent seach engine). That is how I found X1000forums.com when I had a software problem and I immediately rectified my problem by downloading a bios update at HP.
You should consider yourself fortuntate that you have a free dedicated user forum for your specific model only and you should go there periodically or often to learn about updates or issues with your notebook (as well as discounts and best specifications for ordering new models).
Nearly any relevant information on any product or any individual can be easily pulled up using Google or Yahoo search, etc.
I have searched all of hp, talked to online tech support, so far haven't been able to find out how to remove the cd drive in the hp pavilion zd7028cl laptop that I recently purchased, would like to put in a dvd writer which hp sold me without a problem. Please help.
