What version Win7 OS is installed, 32-bit or 64-bit?
If 32-bit it's no use installing more than 4GB of ram as any more than this won't be recognized by the OS and won't be used.

If 64-bit then it supports a maximum of 8GB of ram in your laptop i.e. 2 x 4GB, so the ram module you selected should work with the existing ram module even though looking at the specifications for both modules they are slightly different as one has a latency of CL9 and the other is CL11, so both modules will work at the slower latency of CL11 not that I think that you will notice it.

The [link|http://www.hp.com/ctg/Manual/c03593041.pdf|maintenance and service guide] for the laptop doesn't state whether HP recommends that the latency value has to be the same for both modules or not, (see specifications on p.2) so you can only try and see what happens
