The remainder of the flight was cancelled.
The incident aircraft was able to position back to Stockholm as flight SK-9111 after about 4 hours on the ground in Amsterdam.
On Oct 16th 2012 Netherland's Onderzoeksraad reported they have opened an investigation into the occurrence.
In their quarterly bulletin released on Apr 25th 2014 the Onderzoekraad reported that the investigation has been terminated without a final report. The investigation so far established that the smoke originated from a Multi Function Control and Display unit (MCDU) connected to the flight management system. The smoke dissipated after the MCDU had been disconnected from electrical power. Examination by the manufacturer of the MCDU identified a faulty transistor in the power supply of the MCDU, the impact of the fault remained within the design requirements. Boeing as aircraft manufacturer concluded no further safety measures were needed arguing that the limited release of smoke does not seriously impair the crew and operation of the aircraft. Based on the available checklists, the crew testimonies the DSB concluded the crew responded adequately and quickly and effectively stopped the emission of smoke.
