Como descobrir qual o polo positivo do fio de alimentação de um notebook

Question

Tenho um notebook (desknote) sem a fonte. A fonte antiga que queimou era de 12 V com 3,9 A mas um "técnico" sumiu com o cabo original. Consegui o plug original de 4 pinos para a ligação ao notebook onde apenas dois serão necessários. Como posso descobrir com segurança a polaridade destes dois fios (pinos) para poder ligá-los corretamente à outra fonte que consegui ?
