Paul, there seems to be an issue with that particular machine of yours,
because I have two Lenovo laptops (an Ideapad i5 Z360 and Thinkpad
Core2-Duo X200) that works faultlessly with several different Linux
distribution. I use Dell at work, but will choose Lenovo over and above
Dell for personal use any day. The difference in quality between even
the Dell XPS range (which is a really excellent of lappies) and the
Lenovo X (and even the cheaper T's) series is immediately obvious when
you do a side-by-side comparison.
Having said that, the Lenovo W series is supposed to be their
"powerhouse" models, and doing a bit of research on specifically the
W530 model it is widely reported to be satisfactorily compatible with a
wide range of Linux distros. Your problem sounds somewhat like an issue
with either BIOS and/or SSD firmware incompatibilities, and issue I have
had with my work Dell Latitude E6530 as well. For a while I could not
run Ubuntu (12.04 at that time), but Fedora 18 had kernel patches that
helped. In the end I upgraded my BIOS (which did not help for the SSD,
but fixed other issues), and then swapped out the Samsung SSD for a
newer model (which did the trick). I would also be inclined to run
memcheck to see whether the system RAM checks out.

Legacy does not always mean "bad"! :-) Still, I would seriously suggest
that you start budgeting for a more modern USB2/3 audio interface, and
research what works with Linux. Latency over USB (even USB1) is not what
it used to be, you can get near zero latency with Ubuntu Studio on an
old 64-bit Linux machine. I mostly use an external USB2 (backwards
compatible to USB1) ART Tube interface on both my Ideapad Z360 (1st-Gen
i5, probably the same age as your Apple) and much older Thinkpad X200
(Core2-Duo), and I rarely get any XRUNS recording at 24-bit 48k. I do
get XRUNS on the old X200 (but not on my Z360) when I use my Edirol
interface and record at 24-bit 96k, but that is mostly due to the age
and slowness of the USB chipset in the old Thinkpad.

The X220 is an exceptional machine with reportedly excellent battery
life . I can remember reading a review of it written by Cory Doctorow
(SciFi writer/digital activist) where he sung its praises. He uses
Ubuntu exclusively, so there is no issues with Linux compatibility .

There will be a big difference in performance between the two from a
normal computing perspective, although the T410 is also a fine machine.
However, I don't believe that the performance differences between the i5
and i7 CPUs will make a massive difference for music production, because
the real bottle-neck would be I/O related (USB or FireWire bus, as well
as speed of HDD), and of course RAM. Therefore an i5 spec T410 with a
decently specified SDD won't neccessarily have to stand back to an i7
spec X220 with a "spinning rust" drive. If you do only one thing,
upgrade whatever laptop you use to the max with RAM, so that you get as
much in memory as possible. That way you minimise hitting the HDD, which
is always the slowest part of the data chain.
One last point - as good as your old Firewire audio interface might be,
it is going to start seriously impacting your future technology choices.
If getting rid of the Firewire interface is not an option, consider
getting yourself a cheap desktop machine for home production use that is
easily upgradable with a Firewire interface card, which would mean that
you can still use the audio interface for home studio purposes. By
contrast, USB interfaces are becoming scarily good these days, and they
are also getting a lot smaller and lighter. My ART Tube interface is a
relic by comparison, and almost three times the weight (as well as twice
the size) of it's (sadly non-tube) replacement model. Also, USB
interfaces are also relatively cheap, you can get excellent interfaces
between £80-£300 depending on your use-case. How many interface channels
do you need?
Last thoughts: Your choice between the T410 and X220 is largely academic
IMHO, they are both "boringly good". If you are price-sensitive, the
T410 might be the best immediate choice, although the technical
excellence of the X220 could be the winning factor in the end. I would
play a pricing game between the two, pricing up the individual upgrade
paths and doing a post-upgrade pricing comparison.
