Your friend's system uses an HP TG01-2816nd prebuilt, which likely runs a Ryzen 5 5600G. The question is whether the BIOS and custom B550 motherboard can support a Ryzen 5 3600. Since HP doesn't offer standard parts for older CPUs, compatibility isn't guaranteed. You should check the motherboard's specifications carefully.
Likely. I installed a 2200G in an HP device that previously had a 3700X and it hasn't blown up yet.
