Hey I’m happy to try help unfortunately we don’t have a guide or parts for it available however I might be able to attempt to assist you.
If there are any screws you can see on the bottom of it undo those and try to carefully pry the back cover off otherwise there may be other fasteners securing it such as screws underneath something however I am not familiar with the device but YouTube might have a teardown for you if you look. Once you get the cover off you should be able to see the motherboard if the ram isn’t soldered down you should be able to see it (see image)

If you can see ram looking like that you should be able to buy ram. When looking for ram it is crucial to make sure it is DDR2/3 I cannot tell you which is required as I don’t know your exact model assuming the ram isn’t soldered and you have bought you can find guides to install on YouTube such as this one which is for your device or a similar one ***[link|https://youtu.be/QbgQU7oZ5es|https://youtu.be/QbgQU7oZ5es|new_window=true] ***or this teardown of your device [link|https://youtu.be/F9Mf2zqOCZU|https://youtu.be/F9Mf2zqOCZU|new_window=true]
I hope the has helped and I wish you luck
