This is a troubleshooting guide for the XO laptop. It is geared toward troubleshooting production units running firmware version Q2D03 or greater.
Still very much a work in progress!! Feel free to add
Start Here

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

Common Procedures
The following are common debugging and test procedures:
- Disassembly Guide
- 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 Startup Diagnosis 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.
- Fixing an RTC problem - Fix laptops which can't boot due to reset RTC time.
