The designation of the RAM is not clear in my eyes (and I could not find out more on the HP page). There are two different form factors for the RAM modules:
- one modules are more elongated with 240 pins (mostly more for PCs). Form factor designation: DIMM (30mm x 133mm)
- the other modules are shorter and only have 204 pins (mostly for laptops). Form factor designation: SODIMM 204 (30mm x 67mm)
It is best to take a look at the existing RAM module, then you can see pretty quickly which form factor it is. I assume that the Notbook uses SODIMM form factors, but only a look at the module can confirm this...
