Dell Latitude D630 vs Lenovo Thinkpad T61

The Dell Latitude D630 and the Lenovo Thinkpad T61 are of comparable class, and so many have asked the question of which one is better. I did a lot of research on the two of them and finally came to the conclusion to get the D630, mainly for 1 reason: battery life.

Here I will summarize the information I gathered on the subject in relation to factors that I thought were most important: size, weight, performance, cost, and battery life.


The size is pretty close on these two. I have below used the 14.1″ widescreen T61, since that’s the one that matches the D630. It turns out the T61 is about a millimeter thinner in all directions.

T61: 335.5 x 237 x 27.6 – 31.9 (mm)

D630: 337.1 x 238 x32 (mm)


I call this difference negligible:

D630: starts at only 4.47 lbs
T61: starts at 5 lbs


Both had WXGA+ screen availability, which was important to me. The default processor, an Intel T7250 2.0Gz Duo, is exactly the same in the base model for both. RAM is irrelevant, because you can pick up 4GB of Corsair memory from Newegg for under $65, so there’s no point in upgrading the RAM they include (it costs $400+ for 4GB), or giving extra credit to a machine that comes with 1GB instead of 512MB (because you should upgrade it either way, in my opinion). Hard drives start the same too. The only real difference in starting specs is that the Dell comes with a 6-cell battery while the T61 comes with a 4-cell battery…For me graphics is irrelevant because I don’t play new video games.


At the time of purchase, the cost for similar systems were almost identical. The latitude was slightly (maybe $20) cheaper with basically the same specs, but I just considered them even.

Battery Life

Up until this point, I considered them about even. I probably was leaning toward the T61 because of the reputation Lenovo has for great customer service and long-lasting laptops with no problems. Not that Dell has a negative reputation in either of those categories, but I think consumer opinion is that Lenovo takes the cake. But the battery life is what turned me around.

First of all, the T61 (14.1″ edition) doesn’t have a 9-cell battery option. It only goes up to 7-cell, which, according to the spec sheet, gives up to 6.5 hours (which really means 3 hours of actual use). Furthermore, the optional ultrabay battery is only a 3-cell, and from what I read on the forums, this only gives about an extra 45 minutes to 1 hour of actual use time. On the other hand, the Dell can have a 9-cell primary battery, and a 6-cell media bay battery. Besides this, from what I read on the forums, even with just a 6-cell battery the Dell did significantly better with battery than the T61.


I ended up with the D630. I am very happy with it. I seems to be built very well, I haven’t had any problems with it, and I really do get 4+ hours of battery life (using the computer for browsing, programming, etc) on the 9-cell extended battery. I haven’t seen a need to get the media bay battery yet. I haven’t actually owned a T61 so I can’t give a perfect opinion, but for what it’s worth, I am happy D630 user.

Installing Ubuntu Linux on a Dell Latitude D630

I recently bought a new laptop from Dell. After some difficult option considering, I decided on the Latitude D630 over Lenovo’s T61 Thinkpad. Mostly it came down to the Dell having considerably better battery power.

The D630 came with Windows Vista Basic on it, but I prefer Ubuntu. However, I didn’t want to completely abandon Windows, because sometimes there are programs that I want to run that cannot easily be run on Linux (like computer games). I decided to dual-boot.

I installed the 64-bit edition of Ubuntu 7 Gutsy Gibbon and without much difficulty. The Ubuntu installer guided me through an easy repartitioning of the hard drive by claiming a portion of the Windows partition for the Linux. The Ubuntu boot loader recognized the Windows Vista installation and correctly prompts me on boot which OS to load.

I had no problems with drivers. I had read earlier that some of the integrated Dell wireless cards have some driver issues with Ubuntu, so I elected for an upgraded Intel wireless card. If I recall correctly, everything worked perfectly out of the box, except the sound card. I got instructions for the fix from Martti Kuparinen, whose guide is no longer available:

sudo aptitude install linux-backports-modules
sudo gedit /etc/modprobe.d/alsa-base
options snd-hda-intel model=dell-m42

After a reboot, the sound worked fine. So the installation went really well, and I now use Ubuntu almost exclusively on the laptop. I get 4+ hours of battery life on the extended 9 cell battery.

A few things that I noticed that you may want to consider if you’re thinking about this. First, dual monitor support is difficult. I haven’t been able to get my laptop to connect successfully to a second monitor. Usually I can get it to work in some semblance of the word, but I can only mirror the desktops, and the resolution gives me problems. I was unable to get it to extend the desktop like I wanted it to. This may be due to incompetency on my part, however, as I have only been using Ubuntu (on my desktop) since August 2007, so I’m sure it’s possible. Second, as far as I can tell, there is no way in Ubuntu to instruct the computer to NOT charge the battery, if you have the battery plugged in. I always just have to unplug my battery if I don’t want it charged. But wait, you ask, why wouldn’t I want it charged? Because battery life is prolonged when you don’t leave your battery at max charge all the time. Check out these tips on prolonging lithium ion batteries if you’re interested in more information.

64-bit edition?

Of course I was a bit concerned that installing the 64-bit OS would cause me problems, but it hasn’t been too bad. At this point, they always warn you that some programs may not be able to run on a 64-bit OS, so you’re always safer to just install a 32-bit OS, even if you have a 64-bit processor. In fact, the Windows Vista that came with the laptop was 32-bit…which surprised me, because the processor is 64 bit. I have noticed a few difficulties, though, and I’ll highlight them here. Once again, these may be due to my incompetence, but I’ll present them anyway. First, I seem to have trouble with java applets loading in firefox. For example, the Facebook image upload applet won’t load for me. A quick google search shows one possible solution, but you also will notice that this only works for 32-bit Ubuntu. I also had trouble getting MEGA (bioinformatics software) to work, though they do claim support for Linux through WINE, it only works on a 32-bit OS. But that’s about the limit–I don’t think the 64-bit OS has caused me any other problems.

In conclusion, I think most who are willing to attempt could be successful at installing Ubuntu on a D630.
