I managed to bag a Lenovo Thinkpad T440 for quite cheap as a replacement to my old laptop and I’ve been wondering about upgrading it. Problem is the T440 is quite hostile when it comes to upgrading, unlike the T440p. Replacing, for example, the CPU is basically impossible as it’s soldered directly to the board. And so I’ve been thinking about something stupid a.k.a. replacing the motherboard entirely with a T440s board, which has a better CPU soldered onto it. In theory the two boards should have the same dimensions and should be interchangeable, but does anyone know if that’s actually the case? I couldn’t find much about this kind of swap online, so I thought asking here would be a good idea.
