I recently got an Lenovo T400 and this thing works great with the latest version of Ubuntu (Intrepid).
To install Ubuntu, you have to make sure you edit the BIOS settings and change the graphics to use one of the 2 build in graphics cards. If you want to save the Vista bootloader and access to Lenovo’s restore partition, you must not install grub on the MBR (Master Boot Record). Instead, install grub on the same partition as where the kernel resides. (This will be either /boot or / ) Then install EasyBCD¹ on Vista and add Ubuntu to Vista’s bootloader.
I was going to install Debian on the laptop, but I went w/ Ubuntu Intrepid instead as it has a 2.6.27 kernel which (supposedly) has better support for some the hardware on the T400 (and for my new Sony MP3 Walkman). I could have installed Debian and compiled my own 2.6.27 kernel, but these days I couldn’t be bothered spending ages compiling, testing, and debugging my own kernel.
¹For instructions on how to use EasyBCD see: http://neosmart.net/wiki/display/EBCD/Ubuntu
I’m thinking of getting a new laptop either the Lenova ThinkPad T400 (which is a replacement for the T61), or the IdeaPad U330 to replace my aging Dell 700m
The big thing for me is do they work with Linux (for me specifically Debian or Ubuntu).
And with the T400 you’ll have some work to get everything working smoothy. Such as the dual-graphics cards which is how Lenovo get’s up to 10 hours of battery life from the T400.
I’m torn between either, the small size of the U330, versus the better battery life of the T400 (and the fact that both are a weeeeee bit dear).
OK, I’m tired as I write this, and I find sometimes when I “blog while tired” that my grammar/spelling/ability to make sense suffers, so maybe I’ll rewrite this in the morning. 🙂
