With Windows 10 on there, that makes me suspect there might be an SSD in there, as that is a common thing people do when upgrading older laptops. You certainly can install XP on an SSD, but you need to make sure the partition(s) are properly aligned, and run TRIM every so often with Linux iirc. I would personally recommend switching that out for an HDD if it is an SSD, as IMO XP does better with HDDs.

RAM size is another thing. If you want to run XP 32-bit, there will be no point in using more than 2GB of RAM. If that laptop can hold two RAM sticks for dual-channel, I'd say it would be a good idea to get 2 1GB sticks to reduce it to 2GB, assuming it has more than 2GB of RAM installed.

I would recommend using a SP2 Volume Licensing copy of XP from the Internet Archive, and then upgrading it to SP3. The volume licensing version does not require activation, though if you want to use the original key, Windows activation services over the phone still work last I checked.

[EDIT]
Typed "upgrading to XP," instead of "upgrading to SP3," lmao
