Edit 2: to everyone suggesting an SDD: i know. Look, if this guy had enough $$$ for an SSD, he could buy a used lappy less than half the age of this one that has an ssd and 2-3x the memory....
Fun fact: The machine might even have more RAM. I also had an laptop with a Core 2 Duo. The mainboard supported up to 4GB of RAM. However, the BIOS only supported 3GB (for whatever reason). Around 200MB are used for the iGPU. That left me with 2.8GB of RAM out of 4GB.
Such a great project. Bringing joy to a friend and reduce e-waste at the same time. Love it. Would give away the SSD from my old Core 2 Duo based laptop (which got replaced by a used Gen4 i7 laptop from my company when they sold the devices to employees for very little money. Now they are giving them to schools for free, which is great). Sending it around half the planet is neither free nor sustainable, though. Would be cheaper to buy a new one. But maybe you find someone to help out. For me, an SSD was a great improvement for that old machine. As stated in another comment, upgrading RAM did not work in that particular case.
I just finished setting up Linux Mint for an old buddy of mine on his old dog of a laptop, rendering it useful once again! ( i.imgur.com )
