- IBM T40/T41 difference? And: IBM's dead pixel policy?
- Posted by Florian Kirstein on December 7th, 2003
Hi,
I'm short before buying a Thinkpad, T40 or T41, my current choices are a
T40 TC122GE and a T41 TC12FGE, so XGA 1.3/1.4 GHz Centrino, 256 MB, 40GB
Harddrive. The T41 is about $200 more expensive but has Gigabit
Ethernet and Bluetooth onboard, is there /anything/ besides the
price that would be a point for the T40? Longer Battery runtime due to 0.1
GHz lower speed? I'll be running Linux on it, so the Hard-Disk-Protection
of the T41 might not work anyway as far as I understand it? Is the T41 the
newer series and will replace the T40 on the long run, or will they
run in paralell? All Chipsets (IDE/PCI/USB/...) should be exactly the
same as far as I understand it so there shouldn't new problems with
Linux for the T41 I hope?
Second question: I could get the T40 directly in many shops, the T41 has
to be ordered. How is IBM's policy on dead/hot pixels in the display,
or isn't that an issue anymore on modern Notebooks? I'd prefer not to have
any, are thet considered a defect for IBM warranty?
Thanx & (:ul8er, r@y

I just received a t41p; it has 1 blue pixel stuck on. It's about 10% of the
way down from the top (not a 'central' area) - only noticeable on a totally
black startup screen, and not at all noticeable during normal usage. I'm
not concerned about it.
I have not seen their stuck pixel policy, but you can return it within 30
days no questions asked if you buy it online (as I did). Make sure you use
the EPP program for a great discount if you do buy direct.
So far I am very satisfied with the machine. It is very quiet, long battery
life, has a crisp display and feels rock solid (it had better for the money!
:-D )
Sorry; don't know your other question!

Hi Florian,
I think I am right in thinking that the T40 and T41 are very similar
machines - but I can't say that I've actually been able to compare the two
(I have the T40). I would guess that the shell and most of the components
would be identical. Then there's the hard-drive protection which doesn't
come with the T40, Gigabit ethernet, as you mentioned. However, you would
have thought that they would have tweaked the computer in other ways - Like
it comes with rapid restore ultra, - and little changes like that might make
it a better machine. On the other hand, I doubt it's changed very much,
because the T40 is such a great machine anyway!
IBM's policy on the pixels are a certain limit depending on the number of
pixels on the screen - I think it is several for the 1400 screen, and just a
few for the 1024 screen, for which you can send it back. However, I would
have thought you could send it back straight away if you're not happy with
the laptop even if they're no pixels...
Can't anwser your questions on Linux - sorry.
But I can say that the T40 is a gorgeous machine and I think my one is
great!
Duncan.

Many T40 models have Gigabit ethernet and Bluetooth. You should browse
the IBM Thinkpad website to see the different models. I see no reason
why the HD parking system would not work under Linux since it's built in
to the BIOS and not part of the OS.
There are several different moby/chipset configurations depending on
Ethernet and video display. If you want to run Linux, I would consult
with the Linux on Laptop website to see which models have already been
confirmed as able to run Linux.
The IBM policy on pixel defects is here:
http://www-306.ibm.com/pc/support/si...id=MIGR-4U9P53
It takes a lot of pixel defects for IBM to consider the display
defective. In my own experience managing about 50 laptops (600e, T20,
T23, T30, T40p in various combinations) I have yet to receive a laptop
with even 1 pixel defect.
You can get good pricing on the IBM website so I would just get the
model you want.

Other than the others have said, T41 uses PC2700 DDR vs T40's PC2100 DDR.

Hi,
OK, thanks for all comments, I went for the T41 and already have it
in my hands
It has no dead/hot pixels as far as I can tell :>>
The only negative thing I can say so far is that I possibly should
have gone for a higher display res., not because I need the space,
but because my eyese obviously are too good, I see the subpixels
on the display when I'm close to it which is noticeable especially
on some Linux-X-fonts, I'm used to my blurred CRT, so I'll have to get
used to this TFT effects. The Keyboard is great, the trackpoint/touchpad
combination also seems to be OK, so now I'll have to go for the
linux tweaking to get all the APM and centrino cpu-freq stuff to
work I guess
