Ancient laptop (Caldecott OX14)

If you just want a spare laptop to answer emails and use websites, this would do for you, or as a schoolchild's first laptop. It's been wiped and reset. It runs on Windows XP (!) so not supported any more; battery and broadband work fine, and it has an old (not Microsoft) spreadsheet and word processor, though you'd probably want to use e.g. Google suite if doing anything demanding. Given the ancient operating system you should probably install anti-virus/security software.
