Keyboard backlight T61

#1 Post by steweee » Tue Jun 11, 2019 3:16 am

Hi!
Is there a keyboard on the T61 with built-in backlight? (not a flashlight in the top cover)
Maybe someone bought and installed it?
Or had the experience of installing your own backlight in the keyboard?
I would appreciate the help

Nope, not this type of keyboard.
I remember seeing a failed effort to install one somewhere on the Chineese forum.

I guess this is a "dreamt feature"? :)

Replace the Thinklight with a UV led and the keys legends will fluoresce.
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

The only keyboard that has :
[*] same connector as the T61, and
[*] backlight

is the one from the T430/530, X230 and W530. Problem is:
[*] its keyswitch matrix is not 100% compatible with the T61
[*] the mounting points are completely different

And trying to make the backlight work without burning some component in the system board is going to be an interesting challenge.

I see two challenges:
[*] finding a UV LED of the same size as the Thinklight LED.
[*] soldering said LED without melting/burning the flex cable. :cry:

I have not but given just about anything in the light-grey to white will glow brightly under a blacklight, I'd figure its work a shot.

Challenge accepted.
