Maybe there are no screws on the other side, if there are you may have to remove as many panels from the case as you can and hope you can then reach those screws. Do keep in mind that Compaq probably doesn't want you doing this and may have designed the system in such a way that it's impossible to remove the hard drive with just a screwdriver (of course they'll have some kind of superstrong bolting robot that can open the case in case of RMA).
How do I remove a hard drive on compaq presario sr1311.I can get to two screws facing me but there seems to be screws on the other side?Any ideas?
Yes it does have screws on both sides. Remove both side panels the remove screws . Be sure to unplug your computor frist and touchm the case to remove ststic eletricty. Un plug device then remove screws.
