As noted in ticket <trac>10597</trac> XOs running builds os650, os653 and os656 may encounter a touchpad and keyboard freeze as of January 2011.

You will need:

  • A USB drive (memory stick) of at least 16 MB capacity,
  • Internet access on a computer other than the XO laptop,
  • Power (a wall outlet),
  • 10 minutes

1. Prepare USB drive

1a. Microsoft Windows

1b. Mac OS X

  • insert the USB drive,
  • switch tasks to Finder, display the USB drive, notice the name of the USB drive,
  • create a folder boot on the USB drive,
  • control-click on this link, select Download Linked File As ..., and a Save As dialog will appear,
  • change Where to the name of the USB drive, usually Untitled, then click on the boot folder, then click on Save, the dialog will go away,
  • switch tasks to Finder, display the USB drive,
  • eject the USB drive,
  • go to the Upgrade Firmware section on this page.

1c. Linux - GNOME and Firefox

  • insert the USB drive,
  • create a boot folder on the USB drive,
  • click on the this link, and a dialog window will appear asking you what you want done with the download,
  • save the download to the USB drive in the boot folder,
  • close the Downloads window,
  • eject the USB drive,
  • go to the Upgrade Firmware section on this page.

1d. Linux - Terminal

mkdir boot
cd boot
wget http://dev.laptop.org/pub/firmware/q2d14/bootfw.zip
umount /media/DRIVE


2. Upgrade Firmware

Once you have prepared the USB drive in 1., you should:

  • insert the USB drive into the XO,
  • boot the laptop from the USB drive,
  • you should see a message that the firmware has been upgraded successfully,
  • turn off the laptop,
  • remove the power cord,
  • remove the battery,
  • wait a second,
  • remove the USB drive,
  • replace the battery, and plug the power cord back in,
  • start the laptop.

You should test that the laptop now works normally.


Troubleshooting

If you do not see a message that the firmware has been upgraded successfully, check that the USB drive meets these conditions:

  • it has a boot folder,
  • there is a file bootfw.zip in the boot folder,
  • the partition type of the USB drive is "DOS MBR" rather than "GPT".

If you are not sure about the partition type, and all else fails, try using a different USB drive.
