This is a troubleshooting guide for the XO laptop. It is for troubleshooting production XO laptops running firmware version Q2D03 or greater. While this is intended for use in a repair center, most of the procedures can be followed by users to repair their laptops.

Problems powering on

If you are having problems getting the XO to power on, see Troubleshooting Power On. The Startup Diagnosis page also describes how end users (not repair centers) can debug power-on or boot problems.

Display problems

If you are having problems with the display on an XO laptop, see the Display diagnostics section.

Power and Battery problems

See the Power and Battery diagnostics section if you are having problems such as:

  • the battery is not charging
  • the battery is suddenly loosing charge
  • the laptop won't run from a power adapter

Network Problems

If your laptop is having trouble connecting to other laptops or the Internet, see the Network diagnostics section.

Audio and Camera problems

If you are having problems with the audio (microphone, speakers, headphones, or microphone input) or camera on an XO laptop, see the AV diagnostics section.

Keyboard and Touchpad problems

If you are having problems with the keyboard or touchpad on an XO laptop, see the Keyboard diagnostics section.

USB problems

If you are having problems with the USB interfaces on an XO laptop, see the USB diagnostics section.

Debugging Procedures

The following are common debugging and test procedures:

  • Rebooting the Embedded Controller - This completely resets a laptop
  • A Hardware Self-Test is included in the XO laptop.
  • Boot options - Different boot options are available through pressing buttons around the screen during the initial boot process (immediately after pressing the power button). A sampling (more at Cheat codes):
    • '✓' (check) game pad key: forces a more detailed display while booting. See Troubleshooting Power-On for more details. This is useful for debugging activation problems.
    • 'O' game pad key: alternate between the current boot image and a previous one. In laptops which have never been upgraded, there is no previous boot image to use.
    • Rocker left: invoke hardware self-test.

Repair Procedures

The following are common repair procedures:
