T470 replacing non-backlit keyboard with backlit one

I just got a T470. Excellent computer! I got the Core i7-7600U model with 4gb of memory and a 500gb non-SSD hard disk (T470 20HDCTO1WW, ordered directly from Lenovo). The 2TB SSD and 32GB RAM I got from Crucial work without problem (yes, I ran a memory tester) — although, yes, it’s a moderate pain to take off the back panel (even if you have a special plastic tool for doing so).

 

It’s a really great laptop; I like how clear and bright the display is as well as how fast it runs.

 

That said, on to my question:

 

I got the model with the non-backlit keyboard. Is is possible to upgrade this model to have a backlit keyboard?

 

Here is the information I have gotten from my research:

 

* The dealers selling T470 backlit keyboards warn that it may not be possible to get the backlight to work if the motherboard does not support it (for example, https://www.amazon.com/ThinkPad-01AX569-SN20L72890-Backlit-Keyboard/dp/B0727S1H14/ where they claim “Please check whether your laptop can support backlit keyboard or not before placing the order, if can not, the backlit function of our keyboard will not work!” or https://www.amazon.com/CHNASAWE-Replacement-Backlit-Keyboard-Thinkpad/dp/B071KWWW21/ with a similar “If your original/old keyboard does not have the backlit, this keyboard backlit will not work.” warning)

 

* There is nothing in Lenovo’s T470 service manual at https://download.lenovo.com/ibmdl/pub/pc/pccbbs/pubs/t470/html_en/index_en.html#Replacing_the_keyboa... about only some T470 motherboards supporting a backlit keyboard.

 

* The http://psref.lenovo.com/Product/ThinkPad_T470 page shows that every i7-7600U model has a backlit keyboard (but, then again, my model, the 20HDCTO1WW is not on the list), with only i5-7200U and i5-6200U not having backlight support.

 

* There is nothing in the built in system diagnostics nor BIOS for my T470 saying anything about the motherboard supporting or not supporting a backlit keyboard.

 

* I was able to upgrade my keyboard to a backlit keyboard in my T430 without problem

 

* Searching this forum, I see that that some — but not all — T450s do not have the backlight work when replacing the keyboard: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/Upgrade-non-backlit-Keyboard-T450s-to-a-...

 

* The relevant FRU is some combination of 01AX569 and SN20L72890, but it appears only third party sellers sell the backlit keyboard right now (the only T470 accessories Lenovo is currently selling on their webpage are a couple of batteries)

 

I would guess that all the motherboards support a backlight, or only a couple Core i5 motherboards lack keyboard backlight support, and the dealers are just adding standard boilerplate “it may not work” language, but if anyone knows more about this, please let us know.

Re: T470 replacing non-backlit keyboard with backlit one

Hi bendicion,

  
Welcome to Lenovo Community! And happy to have you again.

First of all congrats Smiley Happy on your newly purchased T470.

As I understand that you have query regarding adding a backlit keyboard to your system.

To get it started I found in Lenovo website that it does have an option to add Keyboard Backlit in your system which could be added with some additional cost.

So Motherboard of T470 has a circuitry for Keyboard backlit & does support backlit keyboard option which can be upgraded later.

And also in psref your model is not listed as its 20HDCTO1WW & CTO model refers Configured to Order

Here are few P/N for backlit keyboards:

  • 01AX487
  • 01AX528
  • 01AX569

I hope the above information helped you.

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,
Prabhansh

Re: T470 replacing non-backlit keyboard with backlit one

Thank you for the reply and for the part numbers. I’m a little annoyed that Lenovo isn’t, as far as I can tell, directly selling these parts yet — I can’t be 100% sure that I’m getting a genuine Lenovo part when ordering from eBay.

 

I still consider this unanswered — until we get the first field report of “I got a T470 without a backlit keyboard, I ordered the backlit keyboard, it worked” (or likewise, that it did not work). Since other lights work on the non-backlit T470 keyboard, I suspect that the backlight will work without problem.

Even I'm agreed with this part that Lenovo is not selling these parts directly yet may this being the new system.

And for this as I have told that in Lenovo website T470 model is available with optional Backlit Keyboard which means there is connector for Keyboard Backlit and it will work fine.

Here are similar discussions this & this in which users have upgraded from non backlit to backlit keyboards.

And also if Backlit keyboard is there in Lenovo website it does means that all system  will support using the same Motherboard used in all systems.

 

Cheers,

Prabhansh

Re: T470 replacing non-backlit keyboard with backlit one

Just a clarification:  There is no extra connector for the backlight.  It simply uses an unused pin on the existing connector.

Re: T470 replacing non-backlit keyboard with backlit one

I was able to find the official store for Lenovo parts. The non backlit US keyboards have part numbers 01AX364 and 01AX405 (depending on who is making the exact keyboard); the official part numbers for US backlit keyboards are 01AX487, 01AX528, or 01AX569 but all three are out of stock at the official store at https://lenovo.encompass.com/ until July 6th (which, I presume, is when T470 parts will start being sold directly to end users).

Re: T470 replacing non-backlit keyboard with backlit one

I ended up ordering two backlist keyboards: I ordered one from eBay with the 01AX569 FRU on the barcode sticker put on the keyboard, and another one from Lenovo’s Encompass official outlet.

 

The eBay one arrived today; the Encompass one is scheduled to arrive in about two months. I put in the eBay replacement keyboard, and everything works: All keys work, and the backlight works without problem, even though my T470 was ordered without a backlit keyboard.

 

The key tops feel a little more slick and less textured then the ones in my non-backlit keyboard; this results in the typing experience feeling a little more “plastic” and less clicky than the other keyboard, but the keyboard is still a great keyboard and it’s nice to have one I can use in a dark room without relying on my touch typing skills.
