More Info:
Recently some posts have been taken and twisted a bit in various blogs and slashdot in to indicate that the keyboard failures are "widespread". As of October 2008, fewer than 150 reports of intermittent keyboard failures have been filed (above).
Richard Smith says :
I would like to clarify what I see as incorrect info about the failure rates of the OLPC keyboard. Please re-post this info however you think best.
OLPC does not have evidence that the keyboard failures are widespread like the blog posts I've seen indicate. The overall RMA return rate of all XO problems combined is less than 1%. Verified keyboard problems are a small part of that.
Please add your reports above to help us gauge the scope of the problem! OLPC needs more accurate data on the failure rate. OLPC invites the community to help.
There has not been a rash of these reports from our deployments, which use the laptops and keyboards more heavily than casual users. The problem was primarily in the early production runs, which made up a portion of G1G1 machines last year.
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.
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.
