Power button doesn't work in Linux. Some key events aren't delivered by acpi.
This is too new hardware for Linux for now. Most probably better support will be there in the future.
Discussion
I am running Mandriva 2009 and it works great except for a few things.
Pretty much all the hardware was recognized automatically, except for the camera and can't get any DVD to play . I haven't tested either the express card slot or the fingerprint reader.
modem is not working. There is strange linux version but you have to pay for fullspeed.
the fingerprint is currently not supported. But may be in the future.
The 2.6.28 and 2.6.29 kernels solves some issues with hibernation/sleep ++
Thinkwiki is really useful for any Thinkpad really. Find our exact spec and move down to the relevant component.

Had a very good experience with T61 / Ubuntu (and Kubuntu) 9.04 Beta
I've no sound, drivers are loaded recognized a conexant cx20651 Hermosa chip.
OpenSUSE 11.1
If i turn on the radio switch only the bluetooth light goes on. Don't know how
to activate the wireless light.
hdaps works!
HDAPS and TP_SMAPI do work on my T400… I had to make a modification to the source code, though.
Modem support
Yes, I have.
I got two version of the hsfmodem driver, one is from the lenovo site for the t61 and another one is latest from linuxant.
Then I install linuxant deb version into the system and after reboot I have workable driver for 14.4. Then I did unpack t61 version and replaced all .O files in the /usr/lib/hsfmodem/modules/imported/ folder from lenovo driver. Then ran hsfconfig for rebuild driver.
T400 & Ubuntu 8.10
All works fine out out box, but i'm not tested firewire, Express Card Slot, and Fingerprint Reader.
Suspend & Hibernation works @ Intel VGA, but i installed suspend and hibernation packets from ubu repository
When you say you installed suspend and hibernation packages from the repos… what packages are you talking about? Do you have exact names for them?
Modem support?
Anyone have luck with the modem?
