I have an American Wii and a USB hard drive.

I plugged them both in using the wrong transformer and now my Wii doesn't turn on anymore, but the USB hard drive still works fine.

Is the Wii completely broken, or is it only the AC adapter? if it was the adapter, I could get a new one from eBay.

This question came from our site for computer enthusiasts and power users.

BOOOOOOOOOOOOOOM!... that's my answer. – r0ca Feb 7 '11 at 19:22
It's more than likely toast, sorry. – Not Kyle stop stalking me Feb 7 '11 at 19:29
You're not supposed to let the smoke out... – Shinrai Feb 7 '11 at 19:31
@shinrai you mean the blue smoke? – Ronan Feb 7 '11 at 21:04

If you know a friend with a Wii, try their AC adapter. If your Wii now works, yay! you just need a new adapter. Otherwise, you'll need a new Wii.

I expect only the AC adapter to be broken; they're usually designed to break themselves (as the cheaper part) instead of passing the breakage down the line and ruining everything.

GameStop sells replacement power adaptors (had to replace my mom's after a lightning strike) – Joe Feb 9 '11 at 14:36

it's possible that the wii itself is fried, but the power converter is almost definitely fried. The way to test if the power converter is fried is:

  1. get a multimeter(they sell them at Home Depot, Lowe's, Radio Shack
  2. plug the power converter into an appropriate socket (110V American)
  3. make sure the multimeter is set to test voltage, in the correct range (i.e.- up to ~100-220V)
  4. connect each tip of the multimeter, one to each tip of the power converter that plugs into the wii

if the needle (or digital readout) says it's anywhere from 100-120V, it sounds like your power converter is fine and it would be the Wii that is fried

if the power converter is fried, it is still possible that the Wii is fried as well. So buy a power converter from a place that has a good return policy (since if you buy a new Wii, the power converter comes with it)

Note: You may be able to find an electronics repair shop that will check the power converter for you for free, so that you don't have to buy a multimeter.

Although I don't own a Wii, I believe the output of the AC adapter would be a low-voltage DC current. Thus, setting the multimeter to 100-220V probably won't be the "correct" way to test it. – Denilson Sá Feb 8 '11 at 20:26
