T25 Frankenpad?

#1 Post by Wolfman_Jack » Sun Oct 29, 2017 9:25 pm

Has anyone yet figured out whether the upper from a T470 or T470s is swappable onto the T25 base?

I'm thinking about getting a non-touch FHD or WQHD options available on the T470/T470s.

T470s uses a different cable and is a different laptop design altogether.

I wound up answering my own question, so I thought I'd post an update in case anyone finds it useful.

I successfully "upgraded" my T25 to use the famed B140HAN01.3 LCD panel. I just had to get the non-touch LCD cable for the T470.

According to the T470 FRU BOM document, the FRUs for that cable are: 00UR481, 00UR482, 00UR483.

Brightness settings and everything else work as expected.


I also successfully installed Windows 7 x64 and can elaborate on that a bit if any other Luddites out there are interested.

Thank you for sharing this information. I am sure it will be useful to many. I imagine the B140HAN01.3 is brighter than the stock IVO LCD?

Personally, I prefer to run Win10 on a machine of this generation, but since may 'Luddites' as you point it out prefer Win7, I believe additional details would be greatly appreciated. :thumbs-UP:

Does replacing the screen void the warranty?

So if the laptop breaks just sneak the old screen back in.

How is the screen still holding up? I get my T25 soon and would love to know if it is worth it to break the warranty?

Is the B140HAN01.3 panel that good for a 14" display? I feel that I am not appreciating my modded T430s that much if this is true.

I would of though there were better color accurate panels by now.

@Saucey:
try calibrating it (this file is from V01_2, but should also work on V1_3): http://www.notebookcheck.net/uploads/tx ... AN01_2.icm

I was of course writing tongue-in-cheek.

There's no real secret trick or anything, but I will put together a set of "tips-and-tricks" and post it in the T25-Retro Support sub-forum when I have the time.

If you know of a better one, I would hazard a guess that any 14" display will work. Some non-Lenovo ones might have screw hole alignment issues. FWIW, even though my B140HAN01.3 had the Lenovo FRU sticker on the back, its EDID is showing as AUO133D rather than LEN40A3 and yet the brightness controls work anyways.
