I have the above computer, Model No. 5410 US, and I am trying to get the hard drive out. It is old enough that HP does not have any manuals or any information, for that matter, on this computer. I was able to take the top plastic front off and get to all of the drives but the hard drive. It is on the bottom. I can't figure out how to get the bottom plastic front off. Any help would truly be appreciated. Thanks.
