The Thinkpad is dead, long live the Thinkpad X230?
5th July 2013

Half a year ago, I reported that I had to find a replacement for my trusty old Thinkpad X41. Unfortunately I did not have much time to spend on it, and it took a while to find a model I believe will do the job, but two days ago the replacement finally arrived. I ended up picking a Thinkpad X230 with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as a roaming workstation, and it seemed to work flawlessly. But my second installation with encrypted disk was not as successful. More on that below.

I had a hard time trying to track down a good laptop, as my most important requirements (robust and with a good keyboard) are never listed in the feature list. But I did get good help from the search feature at Prisjakt, which allowed me to limit the list of interesting laptops based on my other requirements. A bit surprising that SSD disk are not disks according to that search interface, so I had to drop specifying the number of disks from my search parameters. I also asked around among friends to get their impression on keyboards and robustness.

So the new laptop arrived, and it is quite a lot wider than the X41. I am not quite convinced about the keyboard, as it is significantly wider than my old keyboard, and I have to stretch my hand a lot more to reach the edges. But the key response is fairly good and the individual key shape is fairly easy to handle, so I hope I will get used to it. My old X40 was starting to fail, and I really needed a new laptop now. :)

Turning off the touch pad was simple. All it took was a quick visit to the BIOS during boot it disable it.

But there is a fatal problem with the laptop. The 180 GB SSD disk lock up during load. And this happen when installing Debian Wheezy with encrypted disk, while the disk is being filled with random data. I also tested to install Ubuntu Raring, and it happen there too if I reenable the code to fill the disk with random data (it is disabled by default in Ubuntu). And the bug with is already known. It was reported to Debian as BTS report #691427 2012-10-25 (journal commit I/O error on brand-new Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux kernel developers as Kernel bugzilla report #51861 2012-12-20 (Intel SSD 520 stops working under load (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the Lenovo forums, both for T430 2012-11-10 and for X230 03-20-2013. The problem do not only affect installation. The reports state that the disk lock up during use if many writes are done on the disk, so it is much no use to work around the installation problem and end up with a computer that can lock up at any moment. There is even a small C program available that will lock up the hard drive after running a few minutes by writing to a file.

I've contacted my supplier and asked how to handle this, and after contacting PCHELP Norway (request 01D1FDP) which handle support requests for Lenovo, his first suggestion was to upgrade the disk firmware. Unfortunately there is no newer firmware available from Lenovo, as my disk already have the most recent one (version LF1i). I hope to hear more from him today and hope the problem can be fixed. :)
