sorta OT power question for you world travelers
My Dell laptop power supply says that it will work on 100-240V, 50 or 60
Hz. Wikipedia sez http://en.wikipedia.org/wiki/AC_power_plugs_and_sockets that Japanese receptacles, despite having 100V, 50Hz power are essentially identical to a NEMA 1-15. However, both "bricks" that I have use a 3-wire cord instead of a 2-wire like every other laptop I've had/used, and it's not clear to me if a grounding type Japanese JIS C 8303 recep is the same as a NEMA 5-15 or just "similar," or even if they are particularly common. Do I need to pack some kind of adapter plug thing? Or should I just get a cheater plug and carry that? Obviously, I have never been to Japan before... thanks nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

I've used mine on US power with and without a ground, and UK power (230V @ 50Hz) with no problems (but not Japan :-) cheers Jules |

I'll just toss a cheater plug in my laptop bag then and call it good. Primarily I am planning on taking it to watch DVDs on the plane (I have an AC/DC brick with an auto/air cord as well as an AC cord) but hey, if I'm going to cart it with me, might as well see if I can check my email while I'm there too. I don't really have any easy way to generate 100V/50Hz here at my house but I can't imagine it wouldn't work? FWIW my laptop (Precision M90) shipped with a 130W power supply but it seems to be fat and happy here in the living room running off the 65W supply I just got from eBay (that's the one with the auto/air cord. I also tested it off a benchtop 12V power supply and it seems to be good on that too.) I guess I just won't be doing any rendering or any processor intensive stuff while I'm in the air :) Now to remember to get on Project Gutenberg and download lots of books to read too. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

You may find that the circuit breaker trips if you try to run your laptop. If so, removing the battery (thus disabling the charger circuit) will lower the draw enough that the laptop will work. |

Laptop bricks certainly don't. I don't understand what happened that US laptop power bricks now use grounded plugs. The equipment ground dies at the brick. If you bought the Japanese power supply for your notebook it would have a two prong plug that is a tighter tolerance version of NEMA 1-15. My two older notebooks have NEMA 1-15 plugs. |

As everyone else has indicated, you should be fine. I have the same arrangement for my HP computer and I have been to Japan several times and always had a great time. |

For something silly like a grounding plug on a power supply brick, I take a few seconds with the hacksaw and it eliminates the hassles. If the prongs are polarized, a few swipes with a file solve that issue as well. There's no harm, since the brick exterior is non-conductive and the output is low voltage DC, anyway. Maybe if there was a major short inside the brick and 120/240 was delivered to the laptop, the ground might be appreciated, but I'll take my chances. -- Nonny Suppose you were an idiot.

Sure, I just added that there are substantial areas that use 60 Hz because it was noted that Japan uses 50 Hz. |
