Hi:

 

Below is the link to the service manual for your notebook.

 

c01714937.pdf (hp.com)

 

The memory upgrade info can be found in chapter 1 on page 1.

 

2 x 2 GB of DDR2-6400 memory is the max.

Below is the link to the parts list for your notebook.

 

HP PartSurfer

 

According to the parts list, it has a Pentium T4400 processor, correct?

 

While the manual does not list your processor, it lists the T4200, which is in the same family and also supports 2 x 2 GB of memory, as do all of them.

You're very welcome.

 

All you would need to do is to replace the 1 GB chip with a 2 GB chip and also the memory will run in the higher performing dual channel mode.

 

Right now the memory is only running in single channel mode with 3 GB installed.
