The first word in French Polynesia is - French. So how did I so badly ignore that very important fact. If I had been planning to travel to France i would have packed my travel adaptors and brushed up on my French but somehow, it escaped me that the electrical outlets in Tahiti would be based on European not North American standards. Naturally none of my plugs fitted so to recharge my laptop battery I had to get an adaptor. The friendly Francophone guest services man came up with one - but when I plugged it in my poor little laptop was buzzing - literally. I  hope I am not frying its poor little insides. Anyway next day I bought a better adaptor and the buzzing stopped.
