Burn circuits I plugged the wrong power adapter to this device, and now it doesn't work with the correct adapter. There was an electrical order present shortly after this slip-up.

1.Try to plug in other outlet with different circuit breaker.
Try to turn off or unplug appliances with motor (e.g. electric fan ,vacuum cleaner etc.).
2. if buzzing sound still exist isolate the ground prong of your power cord if three pin plug are used by using an adapter.
3. if buzzing sound still exist use isolation transformer.
4. if buzzing sound still exist bring your unit to service center.something wrong with your device.

Having the same plugin doesn't guarantee that it is the correct polarity (if dc) nor the correct voltage, nor that it is AC when you require DC etc. If you put the wrong adapter on and you are not very electrically inclined... you can blow the power circuit inside the unit.

follow this steps and replace batteries too. God bless you


Check power problems if the console on the elliptical machine does not light up. Make sure that the plug for the machine is secure in the outlet. If it is plugged in, ensure that the outlet is receiving power. Check the breaker to make sure it has not tripped off.
Be sure that you are using the correct adapter that came with the elliptical machine. Because different adapters are able to handle differing amounts of energy, the wrong adapter will not transfer electricity like it should. If the adapter is pinched or damaged, this could also alter its effectiveness.

2 Make sure the correct adapter is being used if the resistance settings seem to be too hard or too easy. If the correct adapter is being used, reset the machine. To reset the machine, either switch the "On/Off" button or unplug the machine from the wall. Doing this will allow the device to reset itself to the default resistance. Turn on or plug the device back into the wall and retry all of the levels of resistanc

follow this steps and replace batteries and clean the contacts batteries. God bless you

You have most likely cooked the Wii itself, To check connect the correct power adapter to the correct system and in the correct power source ( 120v or 220v ) if it works all good if not you know you cooked it. If you are unable to test in this manner have it checked by a qualified technician.

try another ac adopter. you mentioned that you change your ac adopter, does your new adopter support dell laptops?

adapter has gone bad or battery charger slot is not working fine

1200 ma provides more power than the 700 ma, and would not be affected by using it on a device that draws 700 ma. The voltage of the charger makes a difference as well as the polarity of the plug. (if it is dc)

If the 700 ma charger is not working, most likely the 700 ma charger is not working

Well Most Likely The Circuit Board Burnet Out Since Its 12V And When Plugged Into A 19V Supply It Will Burn Out Instantly Because It Over Charges The Circuits. So Its Not Possible To Repair Such Damage But You Can Take Out The Hard Drive And Plug IT Into A Desktop Computer And Use It At Home Or As An Online Hard Drive To Store Files
