I will soon be traveling to Ireland and the UK with my nifty new laptop. I have been trying to find out exactly what kind of transformer or converter I will need to use it. I already have the plug adapter, but am finding lots of contradictory info on whether I need a power converter, step-down transformer, or nothing at all. The folks at Compaq were stumped. Can any of you experienced trans-Atlantic FTers help a new kid out? Many thanks!
