Is this keyboard NMB or ALPS or CHICONY?

Part number 42X0133. I searched IBM parts site but it resulted nothing. But this part number is the keyboard of many x61s. Is there a way to know if it's NMB or others?

 

42X0133 is only a part number. You need something called "FRU number" to uniquely identify the part, which will tell you the manufacturer.

 

You can tell by visual inspection. The keyswitches of each of the manufacturers looks different. Try looking under the keys for white switches or blue pads (you may need to remove the keyboard to do this).

Blue pads = NMB
White switches slanting down left (\) = Chicony
White switches slanting up left (/) = ALPS

Hope this helps. As usual if you like your keyboard, it doesn't really matter who made it (mine is Chicony and I like it a lot).

 

Just so you know, if you remove your keys and something bad happens, it voids your warranty.

It's best you check your FRU to be safe.

And, frankly, it doesn't matter what 'brand' it is if you're happy with it. It's true that certain brands have certain trends and properties, but they're all usually solid products. They're Thinkpad keyboards, after all.

 

My x61s keyboard has the FRU number 42T3467 (I just opened up the laptop to check the wifi card, and took a look at the keyboard FRU). According to IBM support site http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67009
this is an NMB.

Edit:
LOL, I thought I was replying to someone's post, but just found out I was the OP! I don't even remember I had asked this question!

 

with all due respect, this is absolutely untrue.   customer-induced damages (caused by stupidity or otherwise) may not be covered under warranty but in no way will removing and breaking keys void an entire system's warranty.

 

Maybe he meant just regarding the keyboard.
