Re: Repairing Thinkpad keys/Keyboards

Depends on the model of ThinkPad you are working with. Older models like NMB made T2x/3x/4x keyboards have the cup weakly glued onto the membrane and you can easily pry it off and it won't be an issue as long as you position it properly before putting the switch down. Did the left control key work ...

Re: Repairing Thinkpad keys/Keyboards

Take the cup out and press it with your finger and see if it registers that way. I'll try the passmark kbtest thing. Aren't the cups glued down? How do you take them off without destroying them? I'm trying to get my head around how these things work. My knowledge of keyboards is quite dated. I unde...

Re: Repairing Thinkpad keys/Keyboards

What part of the keyboard are you looking to fix? The keycaps/switches or the membrane? The former there isn't much substance to it as if its broken you just replace it. The latter can be quite tricky if u don't want an entire keyboard replacement. I have JUST attempted to repair a T520 keyboard fr...

Re: What keyboard P/N do I need?

The 15" model keyboards have only 3 posts (14" have 4). NMB ........ ALPS ...... Chicony 39T0643 - 39T0704 - 39T0765 FRU 93P4780 - 93P4840 - 13N9893 P/N NMB is the one to go for. How can you tell which keyboard the original is? I need to replace one for a T42. I see no indication on the labels of w...

Re: Wanted: T42 Replacement Keyboard

From my knowledge, that is a 15" one with Alps switches. Your keyboards that you've tried and does not work most likely are from 14.1" families. But if you happen to have an 14.1" ALPS one you can still swap around the keycaps and switches. Check the FRU number of the back of your keyboards that yo...

Re: Wanted: T42 Replacement Keyboard

Your problem with the fn key is most likely the keycap or key switch having broken tabs. This kind of stuff happens when plastics get old (though this is still a country mile better than some other home computer key switches) or you didn't put it on properly. I find it kinda ridiculous that they ha...

Re: Wanted: T42 Replacement Keyboard

Yes - three posts - the reason I say the post location is critical is that there are more than one kb with three posts for the 15" machines. And the FRU lists often erroneously list them as interchangeable.

Apparently, this T42 Model JN-US is not the common one...

Re: Wanted: T42 Replacement Keyboard (Photos!)

The Machine is a 2378-REU dated 05/09. And yes, it's T42, 15" Right Control key works fine. Left Control does not respond. Key feels completely normal, but I haven't pulled the cap yet.

Re: Wanted: T42 Replacement Keyboard

The original KB seems to be breaking down. Function Key has come off, and won't stay on. Function and Control seem "shaky". Control is typing an accented "a" and does not work... I tried order two keyboards. They didn't fit. The stud locations are important. There are only three studs on the back, a...
