Last month I blogged about the Thinkpad X301 I got from a rubbish pile . One thing I didn’t realise when writing that post is that the X301 doesn’t have the keyboard light that the T420 has. With the T420 I could press the bottom left (FN) and top right (PgUp from memory) keys on the keyboard to turn a light on the keyboard. This is really good for typing at night. While I can touch type the small keyboard on a laptop makes it a little difficult so the light is a feature I found useful. I wrote my review of the X301 before having to use it at night.
Another problem I noticed is that it crashes after running Memtest86+ for between 30 minutes and 4 hours. Memtest86+ doesn’t report any memory errors, the system just entirely locks up. I have 2 DIMMs for it (2G and 4G), I tried installing them in both orders, and I tried with each of them in the first slot (the system won’t boot if only the second slot is filled). Nothing changed. Now it is possible that this is something that might not happen in real use. For example it might only happen due to heat when the system is under sustained load which isn’t something I planned for that laptop. I would discard a desktop system that had such a problem because I get lots of free desktop PCs, but I’m prepared to live with a laptop that has such a problem to avoid paying for another laptop.
Last night the laptop battery suddenly stopped working entirely. I had it unplugged for about 5 minutes when it abruptly went off (no flashing light to warn that the battery was low or anything). Now when I plug it in the battery light flashes orange. A quick Google search indicates that this might mean that a fuse inside the battery pack has blown or that there might be a problem with the system board. Replacing the system board is much more than the laptop is worth and even replacing the battery will probably cost more than it’s worth. Previously bought a Thinkpad T420 at auction because it didn’t cost much more than getting a new battery and PSU for a T61  and I expect I can find a similar deal if I poll the auction sites for a while.
Using an X series Thinkpad has been a good experience and I’ll definitely consider an X series for my next laptop. My previous history of laptops involved going from ones with a small screen that were heavy and clunky (what was available with 90’s technology and cost less than a car) to ones that had a large screen and were less clunky but still heavy. I hadn’t tried small and light with technology from the last decade, it’s something I could really get used to!
By today’s standards the X301 is deficient in a number of ways. It has 64G of storage (the same as my most recent phones) which isn’t much for software development, 6G of RAM which isn’t too bad but is small by today’s standards (16G is a common factory option nowadays), a 1440*900 screen which looks bad in any comparison (less than the last 3 phones I’ve owned), and a slow CPU. No two of these limits would be enough to make me consider replacing that laptop. Even with the possibility of crashing under load it was still a useful system. But the lack of a usable battery in combination with all the other issues makes the entire system unsuitable for my needs. I would be very happy to use a fast laptop with a high resolution screen even without a battery, but not with this list of issues.
Next week I’m going to a conference and there’s no possibility of buying a new laptop before then. So for a week when I need to use a laptop a lot I will have a sub-standard laptop.
It really sucks to have a laptop develop a problem that makes me want to replace it so soon after I got it.
