The deal is that she is already the user of the T60p, with her Windows installation and data on it. It runs great. However, the T60 that I use as a home server and HTPC has developed an issue where it shuts down with no warning (no Windows logs) once every couple of days, which is obviously no good as a server
especially as it doesn't reboot.
I suspect the temperature sender is bad in some way and sending false intermittent temp readings so the machine shuts down. It is not running too hot, the shutdown is not related to temperature, and I've tried swapping the battery and running with no battery to no avail.
It won't matter to her too much if the machine occasionally shuts down (is unlikely to happen when she's using it considering it happens only once every couple of days on a machine that is on 24/7) so I considered swapping the machines with each other but keeping our own drives (i.e., swapping the drives then swapping the machines with each other) but it means she gets a smaller display (not happy about it) and the nice big IPS panel of the T60p is completely wasted on a server.
So now it makes more sense to me to swap the boards. That way neither of us will notice any external difference. Plus the server will gain the 64 bit CPU of the T60p which could be handy.
How difficult can it be? People on here seem to be doing it all the time.
