Quick fix to the January 2011 touchpad and keyboard problem <trac>10597</trac> that affects operating system builds os650, os653 and os656. Instead of this quick fix, we strongly recommend that you upgrade to the latest version of OLPC OS which has many other improvements. See 10.1.2.

To do this quick fix 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,
  • about ten minutes,

Prepare USB drive

Microsoft Windows

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.

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.

Linux - Terminal

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

Upgrade Firmware

  • 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,
  • insert the battery and power cord,
  • start the laptop and test it.

Problems

  • 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 USB drive has a DOS MBR partition type rather than GPT, (try another drive),
