This is the first of two articles where we will be comparing the ThinkPad T400s against the T400 and X301. Specifically we will be taking a look at the performance and usability of Lenovo’s new ThinkPad T400s compared to its two closests siblings: the “plain jane” T400 and the high end X301.
Lenovo’s ThinkPad T400s is an evolution of the ThinkPad lineup, and a successful at that. It adds just enough new features and changes to be progressive, without rattling the core fundamentals too much. Evolution is one word to describe it, but hybrid actually might be better. The T400s has more in common with the X301 than the regular T400, but we will discuss that in the T400s vs X301 article.
In case you’re unfamiliar with the regular ThinkPad T400, it is undoubtably the bread and butter of Lenovo’s ThinkPad lineup. It has the highest number of sales, the widest array of features, and for a long time the T Series were considered the flagship ThinkPads. I would argue the X300/X301 took that position over in early 2008, but this isn’t the place for that discussion.
So which truly is better? Of course there is no one answer for every user, but hopefully some of the insights here will help you make that decision.

Feature differences
So you’re out shopping for a ThinkPad and now your choices are compounded. You were set on the T400, but this new fangled T400s has popped up. Right off the bat there are a few things that will exclude the T400s from your shopping. If you need:
- discrete graphics
- lower resolution (1280×800) displays
- an ultra-bright display, or
- must have high capacity (>250GB) storage
…then the T400s just won’t work for you. Both systems offer comprehensive docking solutions, but the docks are different (see post on T400s docking here) and you can get an “Advanced” dock for the T400 that has its own graphics card. On the other hand, the T400s docks support dual digital video outputs (DVI or DisplayPort). Both systems have the same hot swappable Ultrabay and performance (on integrated graphics models) is plenty fast with either; the T400 does have faster CPU’s, but they are of little significance for the average user.
Battery Life
One of the biggest differences does come down to battery life. The T400s comes with only one main system battery, a 43 Whr 6-cell that sits under the front of the machine. The T400 offers 4, 6, and 9-cell batteries with capacities 37, 56, and 84 Whr respectively. As you see below in our battery testing, the T400 leads the T400s by a decent pace with its 6-cell battery. The T400 has the option of expanding its runtime by over 50% with the 9-cell, and it of course will take the same 3-cell 29 Whr Ultrabay battery as the T400s for even more runtime.
A quick note about the Ultrabay battery figures below: the + symbol indicates that these would be the added runtimes above whatever main battery is installed. So if you have a T400 6-cell with Ultrabay battery and were watching a DVD, you could expect 3:10 + 1:38 = 4:48 runtime.
| Batteries | 4-cell | 6-cell | 9-cell |
| T400 | 37 Whr | 56 Whr | 84 Whr |
| T400s | N/A | 43 Whr | N/A |
For information on how these systems were tested, please see this page.
Runtime | Scrolling Text + Streaming Audio | 3D Stress Test | DVD Playback |
| T400 6-cell | 4:54 | 3:38 | 3:10 |
| T400 4-cell * | 3:14 | 2:24 | 2:05 |
| T400 9-cell * | 7:21 | 5:27 | 4:45 |
| T400 Ultrabay * | +2:32 | +1:52 | +1:38 |
| T400s 6-cell | 3:58 | 2:46 | 3:04 |
| T400s Ultrabay * | +2:40 | +1:51 | +2:04 |
* = Calculated runtimes based on average power draw during each test, not actually tested
While the T400s returns respectable battery life, it is no match for the T400 that doesn’t have to watch its figure. The results speak for themselves, but I will point out that if you picked up a T400s and the Ultrabay battery (which is the same between both systems), you would have longer batter life than the T400 with its lone 6-cell and still have a much lighter, thinner system.
Regardless, in terms of pure run-time the T400 runs away with higher capacity batteries.
Verdict: T400
Size
While these two machines may be closely related, one is the fat relative and the other skinny. Handling both side by side, there really is no comparison. The new ThinkPad T400s is exceptionally thin and light, really only truly bested by an X301. Having handled a T400 in a corporate environment for quite a while, it suprised me how bulky the once svelte T Series had gotten since the T4x models. Dragging it from meeting to meeting was a chore; how I made do with a 15.4-inch Z61p once upon a time I will never know. (Disclaimer: I am biased, as my primary machine is a 12-inch ThinkPad X61)
Note: I originally intended to call this category “Portability,” but then it struck me that portability is based not only size but also battery life. Since I previously touched on battery life and the size vs battery life aspects of portability are split between the systems, I thought it best to focus on size here.
Verdict: T400s
Usability
Now that we’re done talking speeds and feeds, how does the T400 compare in usage? Things like aesthetics, build quality, port/button layout, and size make a difference in real world usability. Overall usability is definitely improved on the T400s. The larger, more responsive touchpad works well, the screen is plenty bright with better image quality, and the keyboard is a pure joy to type on. This isn’t to say that the T400’s keyboard isn’t amazing, but most people should benefit from the revised layout and the decreased key spacing is a nice touch. Our T400 came with the high-nit WXGA display, so it really isn’t directly comparable, but overall I preferred the T400s’ display. The T400s was plenty bright for most usage and had better overall image quality, plus the higher resolution.
The added focus on VoIP with a dedicated headset jack, mic/webcam mute, and improved 2.0MP webcam is a definite bonus over the T400. If you saw my article on upgrading the T400s, it is a breeze to access the most commonly upgraded components. The T400’s RAM and wireless cards are under the palm rest and keyboard, which can be rather tricky to re-install.
One strong point the T400 does offer is port layout. With more real estate to arrange ports, you’ll find everything on the sides of the machine which are much easier to access, especially only by touch. You do lose out on eSATA, DisplayPort, and the selectively-powered USB port on the T400, but everything comes with a tradeoff.
My final point, and indeed a nitpick to most people, is the system status LEDs. I was deeply in love with the full complement of LEDs on previous ThinkPads, as you could ascertain nearly any aspect of the system’s status with a glance, and from the inside or outside of the machine to boot. The T400s eliminates a lot of that communication and I hate that. But that is probably just me.
Verdict: T400s
Aesthetics
Overall, the T400s comes across as a higher class machine, which it is. While it doesn’t have quite the soft, near plush touch of the ThinkPad X301, the T400s still has a more luxurious feel and look than the “plain jane” T400. For diehard ThinkPadders, the T400s also has the red and blue accents back on the TrackPoint.
The system buttons also look leaps and bounds nicer. Many had criticized the T6x/T400 models for their cheap looking buttons, but I just didn’t see what the problem was – looking at both systems side by side, I do now.
Verdict: T400s
Performance
I’m not one for much nitty gritty performance testing, in laptops anyway. These days, a Core Duo or Core 2 Duo has plenty of power and the system’s overall performance is going to be determined more by RAM capacity and storage performance. Both machines are plenty fast for daily usage and even offer SSDs to speed up the slowest part of the system.
But specs are specs and the T400 will blow the T400s out of the water, when you consider all-out performance. It has Core 2 Duo processors up to 3GHz and NVIDIA discreet graphics options, as well as the same SSDs that the T400s has. If performance is your major criteria, than the T400 will do it faster for cheaper, but let me just reinforce that the T400s is more than adequate for most people’s daily usage.
Verdict: T400
Value
Do I really need to say it? The T400 is of course the better value. You get more performance and longer battery life for less money. The T400s is thinner and lighter, overall a more tote-able machine in my book, but the average user won’t place a large value on that.
Your own priorities will effect just how much of a value the T400 is over the T400s, but in the end it will be significantly cheaper. To give a clear-cut example of the cost difference, I’ve configured two machines as similarly as possible:
| ThinkPad T400 | ThinkPad T400s |
Intel Core 2 Duo Processor P8600 (2.40GHz 1066MHz 3MBL2) 25W Genuine Windows XP Professional (Vista Business 32 downgrade w/Win7) 14.1 WXGA+ TFT, w/ CCFL Backlight Intel Graphics Media Accelerator 4500MHD with vPro 3 GB PC3-8500 DDR3 SDRAM 1067MHz SODIMM Memory (2 DIMM) UltraNav (TrackPoint and TouchPad) with Fingerprint Reader 64 GB Solid State Drive, Serial ATA DVD Recordable 8x Max Dual Layer, Ultrabay Slim (Serial ATA) Express Card Slot & PC Card Slot Intel WiFi Link 5100 (AGN) with My WiFi Technology Integrated Mobile Broadband upgradable 6 cell Li-Ion Battery | Intel Core 2 Duo processor SP9400 (2.40GHz, 6MB L2, 1066MHz FSB) Genuine Windows XP Professional (Vista Business 32 downgrade w/Win7) 14.1 WXGA+ TFT, w/ LED Backlight Intel Graphics Media Accelerator 4500MHD with vPro 3 GB PC3-8500 DDR3 SDRAM 1067MHz SODIMM Memory (2 DIMM) UltraNav (TrackPoint and TouchPad) with Fingerprint Reader 64 GB Solid State Drive, Serial ATA DVD Recordable 8x Max Dual Layer, Ultrabay Slim (Serial ATA) ExpressCard34 Intel WiFi Link 5100 Integrated Wireless Wide Area Network upgradable 6 cell Li-Ion Battery |
$1,408 | $1,679 |
So $271 buys you a thinner, lighter, more advanced machine with several design improvements. Performance should be identical between these two models, although the T400s will be down on battery life and lacks the expandability of the PC Card & ExpressCard 54 slots on the T400. There are also more frequent coupons that offer a greater discount on the T400, whereas the T400s will generally be less discounted due to the premium market it competes in.
The pure monetary value is unquestionably clear here, but the question for the buyer is the value you place on the more advanced T400s.
Verdict: T400

While Lenovo’s ThinkPad T400 and T400s may share a lot of similarity in their namesake, that is really where it ends. The T400s is more akin to the X301 and the features/benefits of each machine can differ drastically.
The value-conscious buyer will undoubtably go for the bulkier, but more practical T400 with its wider range of customization and universally lower price. Those cross-shopping the faux-bretheren will need to have an eye for style and advanced design to really be wooed by the T400s. It is indeed more portable for most people, posting sufficient battery life and a very svelte chassis. I love the dual-display support on the dock too.
Of course, the other scenario for consideration is someone who might look at the T400s as a better, and possibly cheaper, option to the truly class leading ThinkPad X301. That is the topic of our next comparison, so stay tuned!

The T400s comes across as sexy and I really want to like it. But I think several issues went unmentioned:
1) The T400s has a 1.8″ primary hard disk / SSD, and even in the hard disk configurations the nonstandard drive accounts for quite a bit of the extra cost. Yes 1.8″ drives are starting to be more numerous, but we’re still in the era where standard laptop drives are 2.5″. So I think the 1.8″ drive is a serious disadvantage.
2) The “dedicated headset jack” actually means the traditionally separate headphone and mic jacks have been combined into one jack. I hope there is some inexpensive adapter available to separate them out again. I’ve never used a mic/headset with any laptop but I do use normal mics and speakers, o I think this change is a disadvantage; but maybe it is an improvement for VOIP users. Anyway, the main goal of it was likely to save space, rather than improve VOIP usability.
3) The screen does not have as many dpi as other models including the X200S and W500. They should certainly offer this premium machine with 1680×1050 for users who want higher res.
4) I’ve mentioned this before but I think internal optical drives in laptops aren’t that useful any more. I think the T400s made too many sacrifices to accomodate it. Compare the X200s which has standard audio ports, standard 2.5″ disk, and accepts multiple battery options including a 9 cell with 10+ hours of runtime, with the T400s which gives all that up despite being a bigger machine. I would rather they say “Thinkpads are business and technical machines; if you want to watch dvd’s on your laptop, buy an Ideapad”. Then ditch the optical drive and instead have two 2.5″ SATA disk bays. That would make space to allow restoring all the other stuff. But, they are just too pleased with themselves with the technical feat of cramming a DVD drive into the X300, so they couldn’t resist replicating it even though it is useless. Basically they made an overgrown X300 when an even-more-overgrown X200S would have been better.
Also, I don’t understand how it is that you watched a dvd with the 3-cell battery installed in the ultrabay anyway. Doesn’t the dvd drive go there?
Welcome back none
I do wish you’d use a unique name, as someone else can easily come along and steal ‘none’ 
You make a lot of good points here.
1) I see your point and I think everyone will always be divided over this. Yes the move to 1.8-inch limits expansion options. But to get the thin and light design of the T400s, you simply can’t have a 2.5-inch drive unless you were to invest mega-bucks into making such a chassis – then no one could afford the T400s. The mechanical drive options aren’t going to be very fast and for $40, most people will likely splurge for the 64GB SSD in my opinion. Every new SSD that will be coming to market will have a 1.8-inch version, so your longer-term expansion options are far from limited.
2) I agree with you here – I can’t say I’m enough of a VoIPer to know what the availability of these types of headsets or adapters is. And most such headsets have a USB adapter anyway. I need to play with that jack some more.
3) The screen has the highest resolution you’re going to get in a 14-inch size, period. Bottom line is most people don’t want resolution. Let me tell you how many secretaries I’ve seen order 24-inch LCD’s (back when they were a new thing) and set the res at 1024.
4) The T400s didn’t make compromises to include the optical drive – all T Series have and will always a drive bay that will take an optical. Rather I’d say the X300 made compromises to include an optical drive. Some people still do need optical drives – we haven’t gotten to the era of all software is download or shipped on a flash drive yet. One day, but not yet. You also say to ditch the optical for an additional SATA bay – this is already possible, as you know. Putting in a fixed SATA bay would be reducing customer choice – something I’m not a fan of. In the end, the optical may be useless for you, and as you stated, that is why the X200 models are here. They are designed for portability first, extended features/functionality second. I too like the X Series better than the T Series; aside from a weak LCD I rather liked my X200. But the T400s was never intended to replace the X Series, rather it offers the portability of the X with the functionality of the T – and yes, it compromises.
And good catch on the DVD + 3-cell. As noted in the article, I didn’t run those tests but approximated the run-times based on the average power draw of the laptop for each test. If power draw is held consistent, you know how many Watts the machine will draw over a period of time and can find out the additional runtime if you add X Watt-hours of battery capacity. I’ll correct that shortly
Am I missing something?
I have a laptop with what I consider too high resolution I really regret getting it. Even though I can set windows fonts to larger size, can increase the size of word docs’, pdf’s, and even increase the size of web pages in explorer there are still lots of things to small to see and I ended up changing the resolution to less than optimal.
As of windows vista, windows handles DPI scaling more sensibly. With windows XP it used to be that icons and other “images” didn’t scale, so setting your screen to anything other than 96dpi made lots of applications display in weird ways (big fonts, and teeny icons).
Now that legacy applications are properly scaled by windows, and new generation applications are starting to use fully scaleable vector icons and user interfaces, high-resolution screens don’t necessarily need to equate to tiny unreadable text. With a high resolution screen, and your display resolution set to 192 DPI you could enjoy super crisp text and icons.
So the short version is that as software support for high resolution screens matures, having a 15″ screen with 1900-odd pixels across will be a good thing as you’ll get super sharp, detailed text and graphics (on par with print quality) at the same size you would expect to see on a 1024 pixel wide screen.
Hi there John,
was waiting for this comparison as you mentioned it in the review of the t400s. I have a few points/question:
1. You forgot to mention the weight difference between the t400 and t400s, which is in my opinion major. I do not have concrete values though. If it is possible for you, could you also post measured values?
2. I am also fan of those leds informing about the state of the book from the outside and inside as well. Even on the outside the old ones could have more, as many people using docks have their laptops closed. Maybe one could ask the guys from Design Matters, why they chose to include fewer leds.
3. Maybe one offtopic, but, do you know something more about the docking solutions? The advanced plus dock mentions a video controller with it, but I don’t think it is a discrete graphics card. I really miss it with the t400s, any ideas whether Lenovo will release one with a discrete graphics as is for the t400?
4. Back to the hdd/ssds. With Intel releasing his new G2 ssds which are also 1.8″, I think it was a good choice to include just 1.8″ in the t400s. The disc drive is then always good even for those not needing it, because they can replace it for an extra hdd wih the sata adapter or with the battery. Or just leave it blank for extra weight reduction
5. And finally to the mentioned dpi. I have now a z61m which is 15.4″ and has 1680×1050 resolution. Many times I find it too high and wish I could manage 1440×900, but then the text is not sharp enough cos the lcds work perfectly just with their native resolution. How it is with the t400s? Is the text smaller/larger/same as on a 15.4″ machine with 1680×1050? And the setting 1280×800 does still make the text less sharp?
6. PS
you could still watch a dvd from your hdd/ssd, what also extends battery life, cos the optical drive consumes more energy.
Thanx once more for this comparison and I am looking to read the second part, cos I know less about the x301 than about the t400.
Some good questions Sugyi!
Here are the dimensions and weight according to Lenovo’s specs:
T400: 14.1W” (WxDxH): 13.2″ x 10.6″ x 1.1–1.3″; 335.5 x 270mm x 28–32mm
6-cell: starting at 5.0 lb (2.3kg); 9-cell: starting at 5.4 lb (2.4kg)
T400s: 14.1W” (WxDxH): 13.3″ x 9.5″ x 0.83–1.02″; 337 x 241mm x 21.1–25.9mm ; 6-cell: starting at 3.9 lb (1.77kg)
None of the T400s docks have a discrete graphics card to my knowledge. I don’t know about any future docks, but since we reported that future ThinkPads will share the T400s docking connector, I’m going to venture that a future T Series may bring a dock with a discrete card. Although with the separation of T & W Series, hopefully the two will continue to share the same chassis & thus docking connector, making this a possibility. If the W Series changes from the T even more, then there might not be a need for a dock with discrete graphics card for T Series.
John, I agree with you that 1.8″ SSD’s are starting to get traction, they’re just not out in quantity yet. The Intel X25-M is the most attractive of them and its 1.8″ counterpart (X18-M) hasn’t been available in months. There is no 1.8 inch version of the faster X25-E. For the X25-M, most likely the 2.5″ version will be available with double the capacity. Of course I hope this will change. But I feel somewhat burned by the 1.8″ drive in the X40 so I’m leery of repeating history.
Sugyi, according to my calculation your Z61 has 128.65 dpi while the t400s has 121.29 dpi and the x200s has 140.34 dpi. The 15.4″ (?) w500 with WUXGA has 147.02 dpi. By comparison to these, the Blackberry Storm phone has 184 dpi, the Nokia e90 communicator has 218.5 dpi, and the Nokia N810 internet tablet has 227.55 dpi. Also my cheap HP laser printer has 1200 dpi since no one will buy 600 dpi printers any more
. Seriously, higher resolution always looks sharper and cleaner if you’re not doing some awful pixel scaling. People sometimes think higher resolution means smaller letters, but that just means they don’t have their fonts set up correctly. They should configure fonts with more pixels and the size will be the same but the letters will look sharper.
I respect John’s experience with this issue since he deals with lots of Lenovo users while I’m just one unusually geeky one, but really, if I’m hankering to buy an x200s with 140+ dpi, why shouldn’t I want similar dpi on every model? I’ve never understood this. Every time I’ve upgraded a laptop, going all the way back to the 800×600 755cx that replaced a 640×480 Toshiba, it’s been for the sake of higher screen resolution rather than faster cpu or higher disk capacity. And every time I’ve gotten the higher screen resolution I wondered how I had previously lived without it. More pixels on the screen tremendously increases productivity by boosting the amount of stuff you can see and manage. My only downgrade was in going from the UXGA A22p to the WSXGA+ T61 and that was because I couldn’t get the T61p WUXGA screen with Intel graphics. More pixels is like more cpu speed or ram–there’s just never such a thing as too much.
none – you’re pretty much preaching to the choir here. Probably my favorite LCD ever was the 12.1″ SXGA+ on my X60 Tablet. In fact, I’ll be having my X61 modded with that same panel
1440×900 on a 12-inch screen is the best you can get right now. Although I probably wouldn’t mind 1680×1050 on 14-inches!
You make a good point about 1.8 vs 2.5 inch SSDs. I will concede, 2.5 inch would have been a better choice to make the T400s a bit more mainstream. In the end, as great as the T400s is, I too still prefer the X200 as a primary machine. Even on the 6-cell my X200 got awesome battery life, the keyboard was perfect, and the size/weight great – even if it is a bit thick. I really want to get my hands on a 9-cell X200s…
I love my x200s with a 9cell battery (i have a 6-cell too) ;P
It’s almost the perfect thinkpad in size and weight (also have t4x,t61 and some of the older models).
The downside is the intel graphic card and and the lack of dvi on the laptop because the vga is nearly useless these days.
Love the “sturdiness” and pulling it up by grabbing the top corner of the screen and see people try to that with normal laptops.
Seconded … why oh why oh why does Lenovo not put DVI or Displayport on all of its laptops!?
Considering that DVI is backward compatible with VGA (at least when the analogue pins are wired up) and we’re almost all using LCD screens thesedays, being stuck with a VGA port makes no sense!
So please, if anyone at lenovo is listening, let’s see DVI or Displayport on the next batch of thinkpads – I should have had a DVI port way back with my T42, delaying even further is crazyness!
Lifting by the corner of the screen didn’t do my T43p any favours, regardless of how much the lip makes it seem like it’s OK.
After 18 months I had to replace the hinge. Lenovo quoted £230 plus parts for the job BTW, even though machine was in warranty. Found hinge on eBay though.
When is this “soon” of the X301 vs T400s coming?
“The T400 is of course the better value. You get more performance and longer battery life for more money.”
I think you meant to say “for less money”
Thanks Jon

Just want to find if any of these contain a HDMI port to connect LCD TV…
I believe only certain ThinkPad SL models offer an HDMI port, which are essentially re-branded Lenovo 3000 notebooks. No higher end ThinkPads offer HDMI at all.
Is there any alternate to connect to HDMI TV without loosing the clarity??
You can purchase a DisplayPort to HDMI adapter and it will work fine – I’ve used it on the T400s with my HDMI TV. However it will not transfer audio, so you will need a separate cable for that. The W700/W700ds, T400s, and X301 have DisplayPort built-in. The X200 dock also has it. All ThinkPad SL models have HDMI.
The SL series are bit heavy so i dont want to go with that…I am looking for T400s i am impressed with that expect with HDMI… so what cable should i take for Audio??
You will want to convert the 3.5mm mini-stereo output on the T400s to something that your TV supports. This is probably a standard 2-channel RCA connection. Find out what audio inputs are on your TV, then shop online or go to a store and look for a cable that will connect 3.5mm mini-stereo to that connection.
