The first thing is to get a total of 4 GB ram (looks like the max for this cpu) into it and an ssd. These are both very cheap atm. See if there’s a video available for your particular model on the internet about getting into the case for the upgrade. Install a lightweight Linux distro. I have a similar 11 year old laptop and it’s working nicely for browsing/video play etc. with Zorin Lite. Good luck!
