Full Reset
The XO embedded controller (EC) occasionally becomes confused. To reset it, remove all power sources from the laptop:
- Take the battery out and remove the power adapter
- Wait two minutes to allow the embedded controller to lose all power and reset
- Replace at least one source of power (battery or power adapter)
The battery LED should flash orange momentarily (about a quarter of a second) when power is first reapplied. If you do not see this flash, you either have a motherboard hardware problem or faulty EC firmware installed.
The general solution to both of these problems is to replace the motherboard.
