It feels like my several year old PC will crap out soon for one reason
or another, so I need a replacement, better sooner than later.
This time it should be a laptop and I heard that formerly IBM and now
Lenovo thinkpads are of good build quality, even if they only come
with intel CPUs and cost an arm and a leg.
So, do you have any experience with those for audio work?
I'd be most interested in the T and R series and more recent models.
Also helpful would be some data that's impossible to find on websites:
- What chipsets are built in?
- do the usb buses and the like share interrupts with something nasty
like graphics?
Helpful commands to gather that data:
cat /proc/interrupts
lspci
lsusb
Thanks in advance for any help.
Regards,
Philipp

The Thinkpads seem to have a pretty active net community doing sites like
www.thinkwiki.org, which are very helpful. There's nothing bad about Intel
CPUs, actually I consider them the best choice ATM for laptops, especially if
you get a device with an Intel gfx chip inside, they have excellent FLOSS

equivalent laptops cheaper from manufacturers like Acer or MSI, which are the
two companies I have first hand experience with: I have an MSI S260 which
currently gets replaced by an Acer Timeline 3810T. Both are well supported by
Linux. The new one requires bleeding edge software, i.e. Debian unstable in my
case. On the ACER, no interrupts are shared when AHCI is enabled, but I guess,
that's normal for AHCI:

I didn't yet do any hardcore audio tests on that laptop, it's running an
upstream large latency kernel. With laptops, I think, it's important to know
your ways of using it. For example, the Acer is not the fastest device around
(it's just a single Core CPU), but it's very light (1.65kg) and has an amazing
battery life (up to 8h with dimmed display), so it's great to take on the road
which is where I will be using it the most and where I can deal with a slower
CPU, but not with a huge and heavy monster. The other extreme would be a
netbook, but I prefer the 13" screen of the Acer - my eyes don't cope well with

The Z61m is quite large, definitely not thin and light, but it is
sturdy. The reason I got it initially was due to the fact that it had
firewire built in, while the T series did not. You may be able to get
a deal on a slightly older model of thinkpad as it comes off lease.
Unfortunately, I do not know of a good wholesaler to recommend.
I do not know if the T series have similar interrupts, but I will

the x61s, while otherwise a very nice notebook, shares an interrupt
between the 1394 and sata controller, which is kind of nasty when you
want to do hd recording over a ffado device. i ended up adding a cardbus
adaptor to obtain decent latencies.

If not, would it be worth using my usb hard disk as a recording medium?
What cardbus adapter were you using, and how hard was it to make it work
with linux?

I have been using thinkpads since 1999. Back then I bought a i1410
and it is still working! I could not get it to work with audio
reliably back then, it seems that the audio card (some Yamaha varian)
was not supporting full duplex in 44.1 kHz (but in 2205 it did, IIRC).
The computer seems unbreakable.
Anyways, for the past 4 or so years I have been running on a R60e (in
the meantime I broke some T series thinkpad but it was my fault). I
will list the R60e specs below. I use it mostly for live performance.

So, do you have any experience with those for audio
work?
I'd be most interested in the T and R series and more recent models.
Also helpful would be some data that's impossible to find on websites:
- What chipsets are built in?
- do the usb buses and the like share interrupts with something nasty
like graphics?

Hi,
Although I've never used it for serious audio work here's what I got on my
(actually my work-) T60p. The only thing that I found that doesn't work is the
fingerprint reader. That doesn't bother me, because I don't even use it when
running Windows XP. The other annoying bit was that I needed to install the
ATI fglrx driver to get a screen in its native resolution of 1600x1200. Other
than that openSuse 10.3 and up have worked without problems, and I am running
openSuse 11.1 with KDE 4.2.4 for a while now.
I like this laptop, but again, I've never used it for serious music apps. The
closest it comes to that is Amarok. Needless to say that works fine.
Thanks
Paul

I have a T43 and I'm really happy with it. I run Fedora and it runs fine.
I even have the fingerprint scanner running thanks to the info over at
ThinkWiki.org.
That said, the audio chip on this ThinkPad is pretty bad. Recordings
I've made with it have been pretty horrid. If I were going to use it
for serious audio I'd get an external interface, preferably one that
was PCMCIA based as there's no firewire port on it.
The ThinkPads I've had have been pretty rugged and have taken their
fair share of hard knocks and kept working. The other reason I love 'em
is that they have the TrackPoint mouse (the red nub in the middle of the
keyboard) which is brilliant. I *HATE* touchpads, and disable the evil
things on all the ThinkPads I use (3, including work machines, all T43s).
I'll never buy a laptop that has just a touchpad.

That's interesting. I thought there was no driver available for the
fingerprint reader. I'll have to take another look at that.

I recently setup a Lenovo based video editing laptop (Lenovo is one of
the few manufacturers still with some notebooks including firewire port
and non glossy screen) for a friend and wonder what to do with the
fingerprint reader, isnt that a sort of scanner? Maybe like the early
consumer ones, like a big mouse you have to draw over a picture on your
own, anyone remember that times?
Can you do something fancy, maybe controller stuff with the finderprint
reader, what data provides the driver?

I had the idea you could use the fingerprint reader as a vertical scroll
wheel. But it turns out the api is too shallow for that - all the raw
data processing is done in firmware. The api just lets you scan a
fingerprint and return a hash type value which can be compared later on
to other scans.
