Abstract
This disclosure describes techniques for detecting and recovering from faults in computing devices. The faults being detected may consume amounts of power within normal consumption parameters of the device, such as under upper-current protection limits of a power adapter. The power adapter may include components which prevent power from being supplied to the device if the current drawn by the device is not periodically reduced to less than a threshold amount of current. The device may include logic which causes the device to periodically reduce the current drawn from the power adapter to less than the threshold amount of current to reset a timer of the components of the power adapter. Thus, the device may periodically reduce the current drawn when the device is operating normally, but fail to reduce the current drawn when experiencing a fault, which results in the power adapter shutting off power to the faulted device.
