The manufacturers of the keyboard have worked with OLPC to make some changes to the internal construction of the keyboard. We think these changes have helped with the sticky keys issue, and they have been rolled into the current keyboard production.

If you are running a joyride release, you can find your XO's serial number by hovering over your XO person in the center of the Home screen and clicking on "About this XO." Or you can remove the XO battery and read the CSN or SHF number from the barcode attached to the XO.

Instructions

If you currently have an XO with a sticky key then please add your serial number to this wiki page and what key(s) appear to be sticking.

Please don't add a lot of extra info.
A simple one line post entry will be fine. I don't need e-mail addresses or long problem descriptions. If you really have to say something more than oneline you can always post to this page's DISCUSSION & add *pls see TalkPage to the end of your statement above.

If you are running a joyride release, you can find your XO's serial number by hovering over your XO person in the center of the Home screen and clicking on "About this XO." Or you can remove the XO battery and read the CSN or SHF number from the barcode attached to the XO.
