Keyboard Freeze Fixed! Battery needed to be fully charged…


Success! I finally debricked an XO, and finally fixed the keyboard freeze. Thanks to Nate from the Michigan Lending Library, he realized that it may not have been working due to a lack of a fully-charged battery. He was correct.

After learning this fact with a successful attempt with a charged battery, I looked back on the wiki page, and this information was buried in the “How It Works” section. I went back and revised the OLPC wiki page, according to my experience.

Here’s a breakdown of my revision on the wiki (revisions in bold):

Upgrade Firmware

Once you have prepared the USB drive above, be sure that you have a fully-charged battery; otherwise the XO will not complete the upgrade process. After you have verified that the battery is charged, you must:

  • make sure the XO battery is in place and locked,
  • make sure the XO power cord and adapter are plugged in, the battery indicator must be on,
  • insert the USB drive into the XO, and
  • turn on the XO.

Do not interfere at this point, but watch. The upgrade process will begin with several messages displayed. On the screen, you should see a red battery symbol, while the messages are being displayed. Then, the XO will automatically restart. Wait for the XO to restart, then:

  • turn off the XO,
  • remove the power cord,
  • remove the battery,
  • wait a few seconds (with all power disconnected),
  • remove the USB drive,
  • insert the battery,
  • plug the power cord back in, and
  • start the XO.

You should test that the XO now works normally. If it did not work, try the Troubleshooting methods. We recommend pressing the “X” game button method first.
