ThinkPad Keyboards: Classic, Modern and why you can love them both

Posted on June 17, 2023June 8, 2024 by Laptop Retrospective

A quick way to start a debate

One thing that will get long-term ThinkPad users talking is the differences between all of the ThinkPad keyboards and which version is best. This can be a hotly debated topic with a lot of feelings, nostalgia, personal preference and use cases but there are some things I’d like to start with and that is, you are allowed to like them both for different reasons and both have their strengths. When I say “both” what I mean is what most people will talk about and that is the difference between the six-row and seven-row keyboards. There are many that will state that the “classic” or seven-row keyboard remains superior to the six-row or “island” style modernized version. Specific groups will target different models of the seven-row keyboard all the way back to the buckling sleeve M6 and M6-1 variants and if you are getting lost already, you may want to visit Sharktastica’s excellent website on keyboards. This article isn’t designed to make you change your opinion one way or the other, but to provide some information that I have found is often left out of the conversation. Hopefully, you will learn at least one new thing reading this information to either bolster or steel your existing argument or perhaps make you ask some questions.

The “classic” seven-row keyboard is a much-loved keyboard for several reasons, some of which are:

The number of rows of keys,
The dedicated keys that are removed or repurposed,
The switch type,
The key shape,
The key travel.

The “classic” seven-row ThinkPad keyboard as seen on the ThinkPad T420s. Note the square-shaped keys, additional row and blue-coloured enter button.

Some of the above are objective preferences and others will be more subjective in nature but before we dive far into the weeds, I’ll mention this isn’t even the first time I’ve written about ThinkPad keyboards. I strongly suggest you read my first article which looks at a scientific study on key travel that is related to this conversation as it helps shed some light on why we favour certain keyboards over others using ThinkPad keyboards as a test case.

IBM did it before Lenovo

While working on this article, Admiral Shark of Sharkastica, the excellent keyboard website I mentioned at the start of the article, pointed out that IBM was releasing several ThinkPads with six-row keyboard designs before the modern version was even released on the X1. ThinkPads like the IBM ThinkPad 500 and 300C keyboards for example featured six rows. In that regard, the six-row configuration has been around since the beginning. It was certainly not as common as the seven-row design that was found on the flagship models, but there is an undeniable history of six rows present essentially from the beginning.

The Reception and Development of the Modern Six-Row

The more modern six-row ThinkPad keyboard as shipped on the T430s. Note the removal of the ‘IBM’ blue and ThinkVantage text. The island-style keys have spaces between them, but the key shape on the top remains largely unchanged. More modern versions see the removal of the physical buttons above the keyboard with the exception of the power button.

When the new island-style keyboard launched on the ThinkPad X1 in May 2011, it caused quite a stir, so much so that it was addressed in a blog post in July of 2012 trying to explain all of the hard work that went into the design and function of the keyboard. One particular Question and Answer stands out for the level of testing that went into developing the new keyboard:

“We often conduct different evaluations and user tests to maintain or improve the ThinkPad keyboard. However, to determine if and how we would make the changes to our keyboard in 2012, we embarked on one of the most in-depth keyboard studies ever conducted for ThinkPad. We did 350 hours of user testing with people in four countries. With each participant, we conducted 90- to 120-minute one-on-one interviews with hands-on use of different keyboard conditions to understand the latest about keyboard use and design preferences.”

As an aside, the X1 is the spiritual successor to the X301/X300 line of ultrabooks and would evolve into the extremely popular X1 Carbon lineup. In 2019, I got to take a look at an X1 in the video below.

Thanks to Marasu Kamikura, we have some insights as to why the change was made to the six-row keyboard. It turns out that the dedicated keys were being used less and less so they wanted to consolidate the spaces to reduce the overall footprint of the keyboard to make room for other components. Other details about how the laptop closed, TrackPoint height, screen bezels and other design decisions are detailed in the images below. You can click on each image to see a Google Translate version of the text from this briefing on the X1 and the new keyboard. If any readers can provide a better translation, please reach out. I’ve also included a quote from the article above that mentioned the movement of these keys to their new home and how long it takes on average to adjust. All this to say; as users evolved and software changed, so too must the devices we use.

6 row keyboard We reconsidered the functions required on the key top. Even in the business scene, the frequency of using legacy functions (PrtSc, ScrLk, Pause, SysReq. NumLk, Break, etc.) is decreasing year by year. We believe that 7 columns will not be essential for business mobile PCs in the future. We thought it was time to reconsider the weighting of each element in a space-limited product like a mobile PC. A 6-row keyboard reduces the footprint and weight, and expands the possibility of creating more mobile-specific value, such as contributing to thinness and lightness. We are aiming to increase the appeal of this product as a comprehensive product.

Recently, the use of pads has spread. It has come to be able to recognize multiple fingers. We adopted a click pad that achieves both a wide pad area and a comfortable click, as well as a simple appearance.

The plastic decorative frame is thermally welded to the aluminum base plate and integrated to increase the rigidity of the aluminum plate and suppress vibration. 3. Provide a hook on the side of the keyboard to hold down the float on the side. 4. 2 and 3 increase the rigidity of the KBD, and it sticks tightly to the housing, reducing floating.

“We have seen end-users comfortably adjust to these changes in less than an hour. Depending on personal use of these functions, other users may require a bit more time for the change to feel natural. However, this reset has occurred for every end-user in our extensive testing, typically with an ultimate preference for the new layout over the old. Legacy functions like Pause, Break and Scroll Lock are no longer overtly labelled on key tops, but remain accessible via key combinations using the Fn key (e.g., Fn+P = Pause).”

A further connection to ThinkPad heritage

But there exists a connection to the origins of the ThinkPad brand and this newer design that most fans are not aware of and for that, we need to talk about Skylight. Skylight deserves its own deeper dive so I won’t summarize it all here but for the purposes of this article, one should know that device was where this new keyboard was first tested and it makes perfect sense. Both the original ThinkPad and Skylight were designed by Richard Sapper.

Skylight at CES 2010 Photo by Masaru Kamikura. Note the “D” shaped keys on the keyboard.

The keyboard present on the Skylight prototypes and demo models was close to the original wooden prototype ThinkPad that was constructed by Richard Sapper in the early 90s. He referred to these as “D” shaped keys. David Hill discussed this in his blog back in October 2013 which can be found on the Wayback Machine, pictures included.

What I would like to call attention to in this blog is something embodied in Sapper’s work that never quite made it to market on the original ThinkPad 700c. Richard imagined a new key shape that would have a unique contour and profile. He described it as a “D” shape. The intent was to cradle the finger and create a human-oriented soft form that would contrast the strict rectilinear geometry of ThinkPad.

—

The latest ThinkPad keyboard we introduced on products such as the X1 Carbon actually has a key shape reminiscent of this 20+-year-old concept. I made a push to simplify and purify the visual expression of ThinkPad, and I thought the time was right to finally dust off the “D”-shaped key. It took months of hard work, experimentation and analysis to develop and tune the final key shape and relevant force curves. I feel confident that we finally harnessed Sapper’s original intent for our latest ThinkPad designs.

While Skylight would not make it to market, being cancelled six months later its announcement at CES, the keyboard lives on and was introduced on the ThinkPad X1. Taken all together, the six-row modern keyboard has just as much right to be called a ThinkPad keyboard as the seven-row, possibly even more given the connections to its past.

Playing favourites and Retro resurrection

So getting back to the heart of our discussion around ThinkPad keyboards, there is history in every keyboard that has graced the ThinkPad design and they all have good pedigree and merit to their design. As for which is ultimately superior will always be a question riddled with subjectivity right down to the manufacturer of each iteration. Yes, one model or version of a keyboard is often made by several different companies and sometimes small variances end up existing enough though they are supposed to be all built to the same specifications. Some users will even report a different feeling of key presses between backlit and non-backlit variants.

The classic seven-row keyboard did have one last triumph that should be mentioned and that of course is the ThinkPad T25.

The retro-style keyboard that was included on the ThinkPad T25 anniversary model. This keyboard can also be retrofitted to a T480 with modifications.

When David Hill was working on designing the T25, the 25th anniversary ThinkPad, a poll was conducted on the type of keyboard that people wanted to see in that model and unsurprisingly, a retro keyboard was preferred for a retro-styled machine. Considering this machine was being built to harken back to the past, it was appropriate that this specialized keyboard was commissioned for the T25. One should be careful though not to read the data below as an overall preference between the two designs as this device was targeted at a specific group of people and not a wide-scale product. That data would look very different. Needless to say, it is well-loved by many people. As time moves on, fewer and fewer will make this comparison as the older keyboard becomes rarer.

“Preference for a 7 row keyboard was a strong winner. This is clear in both the survey responses and the comments. I’ve included a bar chart on this topic for everyone’s reference.”

ThinkPad knows everything about making a keyboard

One thing is certain in my mind and that is ThinkPads have the best keyboards when compared to any other laptop brand on the market and that is not a surprise to me. When you have spent over 30 years making laptop keyboards, you are going to know a lot about how to do it correctly. That isn’t even counting the years of research IBM did on typewriters and how that research would have bled over to the typing experience in the early days of notebooks. So whether you prefer six or seven rows, backlight or not, picking a ThinkPad keyboard is always a winning move. As for me, I enjoy both keyboards and use them frequently. While this article will likely not change anyone’s mind on such a longstanding and polarizing issue, I hope that it might help inform the conversation better and potentially change some of the language used in those conversations.

The ThinkPads that weren’t Black

Posted on October 22, 2022March 18, 2023 by Laptop Retrospective

Update: This article was updated on March 18, 2023 thanks to the help of Dan Basterfield who worked for IBM UK PC Company. His knowledge has helped increase the overall accuracy of this article.

ThinkPad enthusiasts will likely know that at the very beginning of the history of ThinkPad, black was not the only colour used for these iconic machines. As hard as it might be to believe there do exist Beige/Pebble Gray ThinkPads, it is a strange sight to behold. You can tell by looking at it that the hard work and consideration that Richard Sapper and Kazuhiko Yamazaki put into the design is impacted when the machine isn’t the colour it was designed to be. The Pebble Gray colour choice was available on several models, not just the 700C.

According to the IBM Mobile Systems Hardware Maintenance Manual Volume 2: ThinkPad Computers April 1995, the following models had “gray” part options that were designated “For Germany.” They are listed below:

IBM ThinkPad 700 and 700C (Cream in colour)
IBM ThinkPad 720 and 720C (Cream in colour)
IBM ThinkPad 750, 750P, 750Cs, 750Ce (Grey)
IBM ThinkPad Dock I
IBM ThinkPad 300 Monochrome (See PSREF below)

There was also a Japan-exclusive ThinkPad 330C (5523-JVB) that was beige. This was released on May 16, 1994 and did not feature a TrackPoint and other more recognizable ThinkPad features. We will talk more about that shortly.

It is worth noting that the different colour parts are shared between some models. For example, the 700 and 720 share the same housing components.

So where and why do these machines exist? Let me try and offer as complete of an answer as I can using the information I have collected, some of it recently.

The “Why?” question was partially answered by Arimasa Naitoh during the 20th Anniversary of ThinkPad.

The ThinkPad models in the 1990’s had documentation stating that they are to be made in black cases, in accordance with Richard Sapper’s guidelines set in his collaboration with the Boca Raton Team. Why were there variations from this, where, for instance, the 700/ C, 720C and 300 are in grey?

Naitoh-San: In the 1990’s, we had the retail models of ThinkPad painted in grey to be distinguished from the original enterprise models.

Naitoh-San is likely referring to the Japanese-exclusive ThinkPad 330C (5523-JVB) I mentioned earlier. You can see a gallery of photos of this device that were taken by ThinkPads.com Forum member Bondi.

Official IBM documentation of the Beige/Pebble Gray ThinkPad is spotty at best. In the Personal Systems Reference IBM ThinkPad Notebooks 1992 to 2001 – withdrawn January 2001 – Version 214, the only model not listed as being offered in black was the ThinkPad 300 monochrome model and it was listed as “Charcoal grey” (page 4) as opposed to black. We know from the Hardware Maintenance Manuals from above that there was a more comprehensive offering of ThinkPad in Beige/Gray. This is likely to do with the markets they were sold—more on that in just a moment.

To answer the “Where?” part of the question, we can look at the keyboards and see that nearly all of the photographed examples have one item in common and that is a QWERTZ keyboard layout. I found one example sporting a French European keyboard layout. Both of these keyboard layouts are exclusive to Western/Central Europe and the QWERTZ layout is often simply referred to as the German keyboard layout. Now, this raises an interesting and somewhat plausible connection to the interview I did with Tom Hardy where he discusses the challenges he had with German DIN standards and IBM Germany at the time. See the video below for that whole story.

It is impossible to know how many of these machines were produced but it is highly likely the German DIN standards of the time had an impact on their creation. If we assume Naitoh-san is correct in the above statement at least as it pertains to the Japanese market, where the retail models were designated that colour, Dan Basterfield, a former IBM UK PC Company employee and ThinkPad collector who contacted me also shed some light on how all these histories can co-exist.

“Naitoh-san’s comments about the retail models being grey and business models being black were clearly true for the Japanese market, which saw a proliferation of ‘PS/Note’ branded models for both markets (many of which never made it to the US or EMEA), but not in the context of the non-black 700/720/750/755 models. Yes, the PS/Note 182 was grey, as was the ThinkPad 300, both of which were marketed outside Japan, both were entry-level machines. I acquired a 300 about eight years ago. It is nowhere near as sharp or as iconic as the 700/720, and side-by-side they are clearly different machines. I’d never seen one even in my time at IBM, and it feels disappointingly like a generic laptop dressed up with IBM badges and design cues; IIRC it was manufactured by a 3rd party. The odd texture and the fact that it wasn’t black only emphasised the ‘wrongness’ when I finally got hold of one.

The retail/commercial divide had nothing to do with the cream 700/720 and grey 750/755. These were all due, as you correctly surmised, to the German DIN regulations regarding contrast of visual display units which effectively precluded black (or white) screen surrounds. Not a problem for any of the desktop ranges then, as all the PS/1, PS/2, and ValuePoint monitors were acceptably cream, but a problem for the black ThinkPads, hence the non-black German-only variants. The manufacturing and localisation guys at Greenock confirmed this to me – I asked back then because I’d once had a close look at a peculiar beige/black hybrid ThinkPad, left on a desk in PC Co HQ back in Basingstoke in 1994: black keyboard sitting in a white chassis. I never saw another one like it, even with keeping my eyes open and having good access to oddities and curiosities. I thought it had been a prototype or development chassis, but realised then that this must have been a beige German-market 700/720 that had been retrofitted with a black non German keyboard – presumably UK layout for a UK user. I recently picked up a NOS grey 750/755 German keyboard, like you do, and of course it really is grey (not beige).

What I never even thought to ask about was whether the N33/N55 precursors of the 700/720 were ever sold in Germany (if so, what colour?) since the DIN standard you link to dates from 1984. A lot of big German companies and banks were very loyal IBM customers at that time. I do recall that the cream L40sx was sold in Germany, and I’m pretty sure the one I scrounged for the Helpcentre had a German keyboard. Perhaps IBM didn’t market the black pre-ThinkPads into Germany for this reason… but then again the ThinkPad 350 (re-badged Yamato PS/Note 425, successor to the N33/N51 in that same chassis) is listed in the HMM as having a German keyboard option but no grey casing options, so were presumably sold as standard black, in contravention of the DIN regulations. Maybe they didn’t offer the 350 in Germany, and the German keyboard option was for Switzerland, Austria, etc where presumably the DIN regulations did not apply?”

Study behind the DIN Standards.

Luminance Reflectance Values (LRV) allowed for PC components.

Here is a possibility of how all this comes together by working under the assumption that all the information we have is accurate.

Firstly, as Tom Hardy stated in the interview, the section of the German DIN standards that did not allow computers to be black was revoked sometime after the release of the ThinkPad 700C, this would mean that black could be used for Enterprise machines as Naitoh states in the interview. If the DIN standard was no longer required however then why spend the money to create the gray models for a German market that would no longer require them?

Changing standards takes time and I suspect between Tom Hardy leaving IBM and German businesses slowly moving away from the DIN Standard took just over a year. David Hill also mentioned that recalled some pushback against changing the standards to allow for black machines. If the last ThinkPad that was offered in gray was made in November of 1993 (began manufacture), the standard likely would have been revoked around that time. Some German businesses would be able/willing to overlook the standards and buy the black machine regardless, however, others might have not had that flexibility and the pebble gray was brought in to meet their needs. Perhaps IBM Germany just passed on the cost in the price of the machine.

I also suspect that Japan may have been stuck in the middle of these standards or perhaps wanted to diffeniate a “professional” machine from a consumer one.

After the product lifecycle was complete, it wouldn’t need to offer the gray/beige machines afterwards, standardizing the line and reducing manufacturing costs. Perhaps any remaining inventory was sold off as retail units as Naitoh stated in the interview above. What we can say for certain is, after 1994, no ThinkPads were made in the pebble gray/beige colour.

David Hill also stated in the book “ThinkPad: A Different Shade of Blue” there were other challenges to making ThinkPad the classic black we know today:

“There were a lot of barriers to getting the original IBM ThinkPad design approved. Many were opposed to using black as the color of the notebook. At the time, black was very radical in personal computing, even though it was accepted in earlier computer products. If you went back and looked at the IBM System 360 mainframe from the 1960s, it was primarily black. It was in the computer room behind glass windows and was supposed to look outstanding. The black color allowed clients to show off their prize possession to visitors.

“But personal computers weren’t black at the time. That’s because we wanted to make PCs fit naturally into the office so they wouldn’t be noticed. So, we made all of them in pearl white, a sort of cream color that no one would notice. But, then along comes the ThinkPad, and we wanted to make a bold statement that was just the opposite. We wanted everyone to notice it, so we adopted black. A lot of people objected to our using black as the color of ThinkPad, thinking it wasn’t like ‘IBM.’ Eventually everyone saw it as something that would really differentiate IBM.

Hardened ThinkPad Concept

Posted on March 31, 2022July 19, 2022 by Laptop Retrospective

This post is a short accompanying piece to the recent video I released on the channel

In that video, David Hill shared with me the design concept that Richard Sapper put together to create a rugged or hardened ThinkPad. ThinkPads were already known for being more durable than the competition, but what if that was taken to the next level. Originally, when we were working on the video, there was only one photograph known to exist of the model that Sapper built that David posted on his Instagram years ago. No other images existed.

An AI upscaled version of the photo originally posted by David Hill.

Until now.

Thanks to David, we now have several images of the concept that Sapper built. Brian Leonard, the current VP of Design at Lenovo was kind enough to go into the archives and take some photographs of the model to help tell the story. They appeared in the video, but I have put them below for archival purposes.
