How do I know how much RAM can I upgrade my laptop?

I have a HP Pavilion laptop quite old (2008) which I would like to increase the RAM. Ideally I would like to have 8Gb but I have no idea how to check if hardware could support this extension.

These are the details of the laptop:

Run in the terminal:

sudo dmidecode -t 16

That's what I got in my machine:

# dmidecode 2.12
SMBIOS 2.7 present.
Handle 0x000F, DMI type 16, 15 bytes
Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 32 GB Error Information Handle: No Error Number Of Devices: 2

It means that I can upgrade up to 32 gb and there are 2 memory slots in my laptop.
